Summary: Fragility fractures are a major problem in our aging society leading to early death and loss of independence for activities of daily living. Physical activity in a long-term follow-up of Portuguese women over 50 years with a fragility fracture was associated with better physical function and quality of life. Purpose: To evaluate the long-term impact of physical activity on physical function and health-related quality of life (HRQoL) in women ≥ 50 years old who suffered a fragility fracture. Methods: We evaluated the association of physical activity with physical function and HRQoL in women ≥ 50 years old who self-reported at least one low-impact fracture ≥ 40 years old from the EpiDoC cohort, a population-based cohort. Self-reported data regarding sociodemographics, clinical, and lifestyle behaviors were collected through a semi-structured questionnaire at baseline during a face-to-face clinical interview. During a long-term follow-up, a phone interview was conducted to evaluate physical activity (using a non-validated scale developed for the EpiDoC study), physical function (Health Assessment Questionnaire), and HRQoL (European Quality of Life – 5 Dimension). Women were divided into three groups according to the frequency of physical activity (non-frequent = 0 times/week, frequent = 1–2 times/week, or very frequent = ≥ 3 times/week). The association of physical activity frequency (non-frequent, frequent, and very frequent) with physical function and HRQoL over time was assessed through linear mixed models considering varying intercepts for each woman. Results: This study followed 323 post-fracture women, during a mean follow-up of 3.9 ± 3.5 years. Frequent (β = − 0.1419 [− 0.2783, − 0.0064]) and very frequent (β = − 0.1908 [− 0.2944, − 0.0881]) physical exercise were associated with improvements in physical function relative to non-frequent physical exercise adjusted for BMI, multimorbidity, hospitalizations, alcohol and smoking habits, and the number of fragility fractures at baseline. As for HRQoL, a positive association was found for exercise frequency, specifically frequent (β = 0.1305 [0.0646, 0.1958]) and very frequent (β = 0.1354 [0.0856, 0.1859]) suggesting improvements for HRQoL, in this follow-up period. Conclusions: These findings based on longitudinal data with long-term follow-up suggest that regular physical activity is associated with better function and HRQol among middle-aged and older post-fracture osteoporotic Portuguese women.

Osteoporotic fracture has been understudied in men. In US male veterans aged 50 years and older between 2002 and 2019, hip fracture incidence increased between 2006 and 2019, fewer than 6% of men underwent DXA, and fewer than 0.5% of men were treated. Investigation of low screening and treatment rates is warranted. Purpose: In the United States, the annual incidence of osteoporotic hip fracture is estimated to be 250,000 to 300,000; the one-year mortality in some studies has been as high as 32%. Reports that hip fracture rates in US women 65 years and older may no longer be declining led to this investigation of hip fracture in men, a less studied population. We assessed the trends in the incidence of hip fracture in US male veterans 50 years and older of age as well as the rates of diagnosis and treatment in such men. Methods: We assessed the recent trends of hip fracture incidence in a nation-wide male veteran population 50 years and older of age. Using data from the US Veterans Affairs Informatics and Computing Infrastructure (VINCI) 2002–2019, we calculated the annual age-standardized hip fracture incidence. Secondary objectives included evaluating the annual proportion of hip fracture patients who underwent dual-energy X-ray absorptiometry (DXA) before or after the fracture and/or received osteoporosis medication after the hip fracture over the study period. Results: Hip fracture incidence increased in male veterans from 2006 to 2019. Fewer than 6% of men underwent a DXA scan and fewer than 0.5% received osteoporosis medications up to two years after a hip fracture. Conclusions: Despite available screening methods such as DXAs and medications for primary and secondary prevention of osteoporotic fractures, hip fracture incidence is not decreasing in older male veterans. Our study highlights a need for closer attention to fracture risk in men. [ABSTRACT FROM AUTHOR]

Pediatric bone injuries are traditionally diagnosed using radiography. However, ultrasonography is emerging as an alternative due to its speed and minimal invasiveness. This study assessed the diagnostic capabilities of ultrasound before radiography in a group of 186 children with suspected long bone fractures at Saint Etienne University Hospital (Saint-Priest-en-Jarez, France). Patients with open trauma and severe deformity were excluded. Ultrasonography demonstrated 88.2% sensitivity and 86.4% specificity, with better results for forearm injuries. Of the 186 cases, 162 were consistent with radiography and 24 varied. Factors influencing an accurate diagnosis included the presence of indirect signs, operator experience, and examination duration, while indirect signs often led to misinterpretation. Although ultrasound cannot completely replace radiography due to its limitations in identifying deeper fractures, this study revealed its substantial efficacy and ease, supporting its potential utility in pediatric trauma emergencies.

Background: The increasing life expectancy of individuals with Down syndrome has led to a growing awareness of mid‐ and late‐life conditions. Methods: Based on the Disease Analyser database (IQVIA), this retrospective cohort study compared adults ≥18 years of age with Down syndrome (ICD‐10: Q90) in general practices in Germany with a propensity score‐matched cohort without Down syndrome. The outcome was the first diagnosis of a fracture within 5 years of the index date. The cumulative incidence of fractures over a 5‐year period was presented using Kaplan–Meier curves. Univariable Cox regression analyses by age group and sex were performed to assess the association between Down syndrome and fractures. Results: A total of 2547 individuals with Down syndrome and 12 735 individuals without Down syndrome were included in the study. A significantly higher cumulative fracture incidence within 5 years was observed in the age group 51–60 years (9.3% Down syndrome vs. 4.8% without Down syndrome, P = 0.003) as well as in the age group >60 years (20.3% Down syndrome vs. 8.6% without Down syndrome, P < 0.001) compared with the cohort without Down syndrome. Regression analysis showed a significant association between Down syndrome and fracture risk in women with Down syndrome aged 51–60 years (hazard ratio [HR] = 1.60; 95% confidence interval [CI]: 1.13–2.26), and in those aged 51–60 years (HR = 2.08; 95% CI: 1.27–3.41) and >60 years (HR = 2.98; 95% CI: 1.87–4.73)), but not in men. When comparing fractures in individuals with and without Down syndrome, shoulder and arm fractures were most common in the Down syndrome cohort. Conclusion: The results of our study indicate a positive association between individuals with Down syndrome and subsequent fractures in women and those aged >50 years. Prevention of falls appears to be particularly important in these populations. However, future studies should clarify the extent to which socio‐economic factors, such as housing, play a role in this context. [ABSTRACT FROM AUTHOR]

Purpose: The optimal duration of antibiotic therapy for fracture-related infection (FRI) has not been well defined. Our aim was to assess the recurrence rate of infection in patients who underwent six, 12, or 24 weeks of antibiotic therapy following surgical treatment for FRI one year after antibiotic discontinuation. Additionally, complications were monitored. Methods: Patients with FRI underwent surgical treatment, and antibiotic therapy was initiated. The patients were divided into groups at the 6th and 12th weeks of antibiotic therapy. The primary endpoint was the recurrence of deep or superficial infection at 90 days and one year after the end of antimicrobial therapy. Results: There was no difference in the recurrence of infection 90 days or one year after stopping antibiotic therapy among patients treated for six, 12, or 24 weeks (p = 0.98 and p = 0.19, respectively). The overall recurrence rate of infection 90 days after stopping antibiotic therapy was 4.9% (8/163), and one year after discontinuation of antibiotic therapy was 9.8% (16/163). There was a statistically significant difference in the incidence of adverse effects among the three groups (chi-square; p = 0.01). Adverse effects were more common in the group treated for 24 weeks than in the groups treated for 6 weeks (z score, p = 0.017) or 12 weeks (z score, p = 0.005). Conclusion: Antibiotic therapy longer than 6 weeks did not reduce the recurrence of FRI after one year of follow-up. Additionally, antibiotic treatment for 24 weeks increases adverse events such as skin reactions and acute renal failure. [ABSTRACT FROM AUTHOR]

Introduction: Management of orthopaedic fractures involves acute intervention and follow up through to recovery. Patient-centered care needs to encompass all aspects of this treatment. Limited research is available on outpatient satisfaction and patient-reported outcomes from fracture clinic (FRCL). The purpose of this evaluation is to report on pain levels perceived by patients from minor orthopaedic procedures that were necessary for the continued management of fracture care. Methods: Patients were recruited in the FRCL if they were planned to undergo minor orthopaedic procedures. They were asked to report the pain they experienced at baseline, during the procedure, 20 min post-procedure, and 24 h following the procedure on a verbal numeric rating scale of 0–10. Healthcare professionals (HCP) were then asked to rank their perception of the severity of pain from each procedure type. Finally, qualitative interviews were conducted on a convenience sample of patients. Results: 51 patients were included in this evaluation. Halo pin, external fixation device, Kirschner wire, and screw removal exhibited a mean increase in pain from baseline greater than 3 units during the procedure. The external fixation device removal group showed the greatest pain reported with a statistically significant increase from baseline to the end of the procedure (mean = 7.1; p = 0.002). There was good concordance of pain perception by the HCP to patient experience. Qualitative interviewing revealed two major themes. Discussion: This study provided valuable qualitative and quantitative insight into the pain perceptions by FRCL patients. This data may help improve the patient experience inside the FRCL.

Background: Chronic low-grade inflammation is related to bone metabolism in patients with type 2 diabetes mellitus (T2DM). However, credible data indicating the relationship between inflammation and fragility fracture risk in postmenopausal anemic females with T2DM are sparse. The current study sought to investigate the relationships between the systemic immune-inflammatory index (SII) and fragility fracture events, as well as the future 10-year fragility fracture probability evaluated using the fracture risk assessment tool (FRAX) in postmenopausal females with T2DM. Methods: According to the tertiles of SII, 423 postmenopausal females with T2DM were divided into three groups: low-level (≤ 381.32, n = 141), moderate-level (381.32–629.46, n = 141), and high-level (≥ 629.46, n = 141). All participants were followed up for 7 years with a median of 46.8 months (1651 person-years). The association between SII and fragility fracture risk was assessed. Results: Of 423 subjects, 75 experienced a fragility fracture event. Spearman partial correlation analysis revealed that SII was negatively related to bone mineral density (BMD) and was positively associated with the future 10-year probability of major osteoporotic fracture (MOF) and hip fracture (HF). Restricted cubic spline (RCS) analysis revealed a positive correlation between SII and fragility fracture risk in an approximately inverted J-shaped dose–response pattern (P for overall < 0.0001). Multivariate Cox regression analysis demonstrated that patients with a high SII presented a greater risk of fragility fractures (P = 0.011). Stratified analysis revealed that fragility fractures in the high-level SII were predominantly associated with anemia with an increase of 4.15 times (P = 0.01). Kaplan‒Meier analysis indicated a greater cumulative incidence of fragility fractures in patients with a high SII (log-rank, all P = 0.0012). Receiver operating characteristic (ROC) analysis indicated an optimal SII cut-off value of 537.34, with an area under the curve (AUC) of 0.646, a sensitivity of 60%, and a specificity of 64.1% (P < 0.001). Conclusion: The SII revealed a significant positive association with a real-world fragility fracture event and a future 10-year fragility fracture probability in postmenopausal females with T2DM, particularly evident in individuals with anemia. Therefore, monitoring the SII and hemoglobin in postmenopausal older women with T2DM is helpful in routine clinical practice to identify individuals at high risk for fragility fractures and to promptly execute appropriate fracture intervention procedures.

Background: Tourniquets are widely used in limb fracture surgeries. Controversies still exist about the pressure inflated, including unified tourniquet inflation pressure (UTIP) and personalized tourniquet inflation pressure (PTIP). This study evaluated the hemostatic effect between UTIP and PTIP based on systolic blood pressure (SBP) in extremity fracture patients. Materials and methods: Patients with fresh extremity fractures requiring tourniquets during surgeries were prospectively enrolled and randomly assigned to the UTIP and PTIP groups. The inflation pressure was set to 250 mmHg for the upper extremities and 300 mmHg for the lower extremities in the UTIP group and SBP plus 50 mmHg for the upper extremities and SBP plus 100 mmHg for the lower extremities in the PTIP group. The primary outcome was a hemostatic effect evaluated by the surgeon (satisfied or dissatisfied). Other secondary outcomes included postoperative changes in limb swelling and tourniquet-related complications. Results: A total of 144 patients were enrolled and randomly assigned to the UTIP group or the PTIP group, and each group has 72 patients (36 upper limb and 36 lower limb). Totally, the hemostasis effect of the PTIP group was worse than that of the UTIP group by non-inferiority test. The hemostatic effect of upper limb fractures with SBP plus 50 mmHg for tourniquet inflation pressure was also worse than that with 250mmHg; however, there was no statistically significant difference between 300mmHg and SBP plus 100 mmHg in the lower limb group hemostasis effect due to a lack of power. Also, no difference was observed in the incidence of complications (p = 1.000) and postoperative changes in limb swelling during 2 days after surgery (upper limb: P1 = 0.546, P2 = 0.545; lower limb: P1 = 0.408, P2 = 0.857) between the PTIP and UTIP group. Conclusion: In the surgery of limb fractures, setting SBP + 50mmHg as tourniquet pressure may not be sufficient for upper limbs. Also, we found no difference between the SBP + 100mmHg and the unified 300mmHg for lower limb surgeries. [ABSTRACT FROM AUTHOR]

Background: Fragility fractures have significant sequelae, including pain, loss of mobility, and increased risk of mortality. Fracture liaison services (FLS) represent a coordinated, interdisciplinary approach to secondary prevention and reduce mortality. Purpose: To investigate the effectiveness and patient outcomes regarding readmission and mortality of a newly developed, nurse practitioner (NP) coordinated FLS in Chile. Methodology: Retrospective longitudinal analysis of 214 patients who agreed to participate in a FLS was conducted. Variables studied include patient age, gender, anatomical fracture site, dual x-ray absorptiometry scans, medication, readmission information, and mortality. Demographics and clinical data were collected and analyzed with bivariate and multivariate statistics. Kaplan-Meier curves and log-rank tests were performed to compare survival curves between those who did and did not participate in the FLS. Results: The study sample was predominantly female (85%) with a mean age of 76 (SD: 12; range 41-101) years. The most frequently noted fracture sites were hip (n = 167), wrist (n = 132), and spine (n = 72). At one-year follow-up, the FLS group had a significantly lower mortality (5%, 10 patients) than those who did not participate in the program (12% [N = 50], p = .005). The Kaplan-Meier analysis indicated that patients who participated in the FLS had significantly better survival rates than those who did not participate. Conclusions: Significantly improved survival rates were observed in FLS patients. Chile's first FLS demonstrated improved patient outcomes, specifically a reduced mortality in patients who were enrolled in the FLS. Implications: The NP role was fundamental in the screening, diagnosis, and treatment of patients with osteoporosis. [ABSTRACT FROM AUTHOR]

Objective: We investigated if theta burst stimulation could enhance recovery by reducing key symptoms when implemented acutely post fracture in participants with an isolated upper limb fracture. Methods/Design: This was a pilot study with a randomized matched pair, sham-controlled, participant-blind design of a 10-day prolonged continuous theta burst stimulation protocol. Two main groups were included: I) participants with isolated upper limb fracture receiving active theta burst stimulation and II) patients with isolated upper limb fracture receiving SHAM/placebo. Another group (III) of healthy individuals was the reference group. Disability and pain intensity were collected through questionnaires (disabilities of the Arm, Shoulder, and Hand as well as numerical rating scale (NRA)) at three time points (baseline; 72 hrs after intervention, 3 mos after injury). Group III completed the baseline assessment. Results: Seventy-nine participants were enrolled. Individuals in the ACTIVE and SHAM groups had similar baseline measures. For disability, the interaction between intervention and time approached significance (F = 2.33; P = 0.11), whereas it was significant for pain (F = 3.42; P = 0.04). At 3 mos after injury, the ACTIVE group reported reduced disability (F = 4.71; P = 0.04) and pain (F = 5.84; P = 0.02) at 3 mos after injury compared to the SHAM group, with clinical measures from ACTIVE group being like controls. Conclusions: In isolated upper limb fracture patients, a 10-day theta burst stimulation intervention implemented acutely posttraumatic had beneficial effects on symptoms of functional recovery and pain at 3 mos after trauma.

Summary: People with prior lean mass loss had a ~ 10% higher risk of MOF and ~ 22–26% higher risk of hip fracture, and the results were similar in people on anti-osteoporosis medications. Loss of lean mass is associated with increased fracture risk. Patients should be encouraged to pursue strategies to prevent loss of lean mass. Background: Sarcopenia increases fracture risk. If the risk persists after starting osteoporosis medication, patients may need to be encouraged to pursue strategies to prevent loss of lean mass. Objective: To estimate the effects of loss in appendicular lean mass (ALM) or total body lean mass (TBLM) on subsequent fracture risk and effect modification with anti-osteoporosis medication use. Methods: We conducted a registry-based cohort study linked to population-based data. We identified individuals ≥ 40 years of age with two DXA assessments ≥ 1 year apart and minimum 0.5 years of observation. ALM and TBLM were estimated from weight, sex, and percent fat from DXA (R2 = 0.91 and 0.84 vs total body DXA, respectively). We report hazard ratios (HR) from Cox regression models estimating time to first incident major osteoporotic fracture (MOF) and hip fracture, adjusted for fracture risk; osteoporosis medication was included as an interaction term and used to stratify analyses. Results: We included 21,249 individuals (mean 67 [SD 10] years, 95% female, 37% on osteoporosis medication). The mean follow-up was 7 years (SD 4). A total of 1868 and 548 people had incident MOF and hip fracture, respectively. People with prior ALM loss (HR per SD 1.09, 95% CI 1.04–1.15) or TBLM loss (HR per SD 1.09, 95% CI 1.42–1.14) had a higher risk of MOF. Hip fracture risk was greater in people with prior ALM loss (HR per SD 1.22, 95% CI 1.12–1.33) and TBLM loss (HR per SD 1.26, 95% CI 1.16–1.38). There were no interactions with anti-osteoporosis medication use (all p > 0.3). When restricted to people on anti-osteoporosis medication, each SD in ALM or TBLM loss was associated with 8–9% increased MOF risk and 18–23% increased hip fracture risk. Conclusions: Loss of lean mass is associated with increased fracture risk among individuals on anti-osteoporosis medication. Patients should be encouraged to pursue strategies to prevent sarcopenia.

Purpose: This study evaluates sex differences and predictors of anti-osteoporosis medication (AOM) use following a hip fracture, with a focus on older men who exhibit higher mortality rates post-fracture compared to women over the age of 65. Methods: Participants included 151 men and 161 women aged 65 and older with hip fractures. The outcome, AOM use, was assessed at baseline (≤ 22 days of hospitalization) and at 2, 6, and 12 months post-hip fracture. Generalized estimating equations (GEE) modeled sex differences and predictors of AOM use during the year post-fracture in 255 participants with complete baseline data and ≥ 1 follow-up observation. Results: Of the 312 participants, only 53 used AOM at baseline, and 35 initiated use during follow-up. In the unadjusted GEE model, AOM use was significantly less likely in men (OR = 0.42; 95% CI, 0.22–0.78) compared to women. For both men and women, baseline use of AOM was a significant predictor (OR = 28.3; 95% CI, 5.4–148.0 vs. 41.6; 95% CI, 14.0–123.0). The other significant predictors by sex were osteoporosis diagnosis (OR = 3.19; 95% CI, 1.16–8.77) and minimal alcohol use (OR = 3.26; 95% CI, 1.34–7.94) for women versus age (OR = 1.09; 95% CI, 1.01–1.18) for men. Conclusion: In older adults with hip fractures, AOM use is low over the year post-fracture and men are less likely to report AOM use compared to women which has implications for important sex differences in predictors of use. Further research is needed to address overall disparities and sex differences in AOM use. [ABSTRACT FROM AUTHOR]

Summary: Androgen Deprivation Therapy (ADT) increases long-term fracture risk in prostate cancer. Our study showed a higher fracture risk within six months of ADT use, and current use was associated with a higher risk of fragility fractures. Attention is needed for the prevention of fragility fractures at the start of ADT. Purpose: Androgen Deprivation Therapy (ADT) is known to increase long-term fracture risk in men with prostate cancer (PCa), although the risk of fragility fractures remains unclear. This study aims to evaluate the risk of fragility and malignancy-related fractures in men with PCa treated with ADT. Methods: We conducted a retrospective cohort study of men with PCa. Follow-up time was divided into 30-day intervals and exposure (current, past, or no-ADT use). Current ADT use was stratified by duration of ADT use (≤ 182 days, 183–730 days, and > 730 days). Cause-specific Cox proportional hazard models were used to estimate the risk of fractures. Results: We included 471 patients (mean age 70.5 (± 8.3) years). The mean follow-up time was 5.0 (± 1.7) years in patients who never started ADT, 3.4 (± 2.3) years and 4.1 (± 2.0) years in patients who started ADT at baseline and during follow-up, respectively. In total, 60 patients had a fracture, 48 (80%) fragility, and 12 (20%) malignancy-related fractures. Current ADT use was associated with a higher risk of all fractures (HR 5.10, 95% CI 2.34–11.13) and fragility fractures (HR 3.61, 95% CI 1.57–8.30). The association with malignancy-related fractures could not be studied due to no events during no-ADT use. There was an increased risk of all fractures with longer duration of ADT use. Conclusions: Current ADT use was associated with a higher risk of fragility fractures than no-ADT use. A higher fracture risk was observed within the first six months of ADT use and persisted for longer durations. [ABSTRACT FROM AUTHOR]

Summary: Examining fracture dynamics by socioeconomic status may inform healthcare and prevention. We found a higher risk of hip fracture in men and women with lower educational level in Norway. However, by age 90 + years, the cumulative incidence was higher in those with higher education, due to their higher life expectancy. Purpose: Socioeconomic gradients are seen for several health outcomes in high-income countries. We aimed to examine possible educational gradients in risk of hip fracture in Norway and to describe the cumulative incidence of hip fracture by educational level. Methods: In a population-wide cohort of Norwegians aged ≥ 50 years, information on attained education from Statistics Norway was linked to hospital-treated hip fractures and deaths during 2002–2019. We estimated relative fracture risk by educational level (primary, secondary or tertiary) in Cox proportional hazards regression. We also examined the cumulative incidence over attained age by gender and educational level in competing risk regression. Results: The population included N = 1,389,858 individuals with 135,938 incident hip fractures. Compared with men who had attained tertiary education, hazard ratios (95% confidence intervals) for hip fracture were 1.44 (1.40, 1.49) in men with primary education only and 1.26 (1.22, 1.29) in men with secondary education. In women, the corresponding estimates were 1.28 (1.25, 1.31) and 1.16 (1.13, 1.19). In the age range 50 to 90 years, the highest cumulative incidence of hip fracture was seen in those with primary education. The gradient gradually diminished with advancing age and was reversed in the oldest (> 90 years) in both genders. Conclusions: There was a clear educational gradient in hip fracture incidence in both men and women in Norway, with a higher risk in people with lower education. Despite this, the cumulative incidence of hip fracture in old age was highest among people with higher education, due to their higher life expectancy. [ABSTRACT FROM AUTHOR]

Background: Displaced femoral neck fractures frequently result in considerable patient morbidity, with complications such as postoperative femoral neck shortening occurring in up to 39.1% of cases. This shortening is associated with reduced hip function and mobility. The Femoral Neck System (FNS), which allows for controlled sliding to facilitate fracture reduction and healing, may mitigate these issues. However, the ideal sliding distance to balance fracture healing and minimize complications is not well defined. Methods: We performed a retrospective cohort study of 179 patients who underwent FNS fixation for displaced femoral neck fractures at our institution from September 2019 to September 2023. Patients were categorized into three groups based on the intraoperative sliding distance allowed by the FNS: the Minimal Slide group (≤ 5 mm), the Moderate Slide group (> 5 to ≤ 10 mm), and the Extensive Slide group (> 10 to 20 mm). Primary outcomes included postoperative femoral neck shortening, the incidence of moderate to severe shortening, time to fracture union, and hip joint function as assessed by the Harris Hip Score (HHS) and the Parker Mobility Score. Secondary outcomes included complication rates such as implant cut-out, nonunion, avascular necrosis of the femoral head, and the need for secondary surgery. Results: The Extensive Slide group of moderate to severe shortening at 32.31%, which was 1.59-fold and 8.88-fold that of the Moderate Slide (20.34%) and Minimal Slide group's (3.64%), respectively (P < 0.01). The sliding predominantly occurred within the first three months postoperatively and had substantially ceased by six months. At one year postoperatively, the median shortening was 2.7 mm (IQR, 0.7 to 3.5 mm) for the Minimal Slide group, a value that was notably lower compared to the 3.2 mm (IQR, 2.4 to 4.6 mm) for the Moderate Slide group and the 3.5 mm (IQR, 1.3 to 8.1 mm) for the Extensive Slide group. The average time to achieve union was similar across all groups, with no significant differences. Functional outcomes, as assessed by the Harris Hip Score (HHS) and the Parker Mobility Score, the Harris Hip Score (HHS) demonstrated statistical significance, the Parker Mobility Score did not reach statistical significance. Conclusions: Restricting FNS slide to ≤ 5 mm in surgery may reduce shortening, improve hip function, and not hinder fracture healing or implant stability. Considering the key 3-month sliding timeline postoperatively is advisable in clinical practice. Further research with a broader patient cohort is vital to confirm these findings and to anchor them in evidence-based practice. [ABSTRACT FROM AUTHOR]

Background: Medical education related to bone fracture must address numerous challenges including complex anatomical characteristics, diverse injury mechanisms, fracture typing, and treatment modalities. Our newly developed 3D printed model comprises components that may be combined or split to simulate various anatomical features, fracture types, and treatment modalities. This study aims to analyze the teaching utility of the new 3D-printed model compared with the traditional solid model. Methods: This prospective study included 112 students randomly assigned to fracture-related education with a conventional model or the newly developed 3D-printed model. All students received 40 min of lecture, 20 min for femoral neck and 20 min for tibiofibular fractures, and a post-class quiz (10 min each) immediately followed. Scores on tests of fracture-related knowledge and user satisfaction were measured pre and post education for comparison. Results: The 3D printing group had an advantage in retention of anatomic knowledge, fracture typing and choice of treatment for the femoral neck fracture (P < 0.05). For the tibiofibular fracture the 3D printing group had an advantage in retention of anatomic knowledge and fracture complications (P < 0.05).Scores on the questionnaire survey also showed increased satisfaction in the 3D-printed model group(P < 0.05). Conclusions: The proposed 3D-printed model can enhance the teaching effect significantly and has potential for widespread use in medical student education. [ABSTRACT FROM AUTHOR]

Aims: This study aimed to compare outcomes of internal fixation and non-operative management in younger adults. Methods: A retrospective cohort study was undertaken in patients aged 18–55 with 2-part or 3-part proximal humerus fractures at a Level 1 trauma centre from January 2010 to December 2018. Outcome measures were the Oxford shoulder score (OSS), EQ-5D-5L, and radiological outcomes. Complications recorded included further surgery, loss of position/fixation, and non-union/malunion. Statistical analysis included univariable analysis and multivariable analysis performed using binary logistic regression and linear regression. Results: A total of 184 eligible patients were included; 99 underwent operative fixation and 85 were managed with sling immobilisation. The mean (SD) age in the operative group was 39.3 ± 10.6 and in the non-operative group was 43.2 ± 10.8 (p = 0.02). Seventy-seven percent completed a minimum 12-month follow-up (median 3.2 years, IQR 2–6.5 years). Most 3-part fractures were treated surgically (78%), as opposed to 44% of 2-part fractures. All open fractures, all segmental fractures, eight head split fractures (89%), and 12 fracture-dislocations (80%) were treated surgically. There was no difference in mean OSS (43.7 operative vs 42.1 non-operative, p = 0.27), mean EQ-5D-5L utility score (0.81 vs 0.78, p = 0.32) or proportion returned to work (83% vs 75%, p = 0.34). Adjusted for case-mix, there was no difference in OSS (adjusted mean difference 0.24, 95%CI −2.73 to 3.22, p = 0.87) or EQ-5D-5L utility score (adjusted mean difference 0.00, 95%CI −0.06 to 0.07, p = 0.96). The complication rate was high (36% non-operative, 27% operative, p = 0.24). A higher rate of varus malunion was observed in the non-operative group (24.0% vs 41.4%, p < 0.001). Following operative management, 23% underwent subsequent surgery compared with 7% of the non-operative group (p = 0.002). Conclusion: In younger adults with proximal humerus fractures no differences in patient reported outcome measures were observed between groups. Operative management was associated with improved radiological outcomes, but a higher rate of subsequent surgery. [ABSTRACT FROM AUTHOR]

Summary: In this retrospective cohort study of adult stem cell transplanted patients (n = 8463), a significant increased risk of both MOF and hip fractures was seen compared with the Swedish population and occurred in mean more than 2 years after stem cell transplantation. Purpose: To explore the risk for osteoporotic fracture in patients who have undergone hematopoietic stem cell transplantation (HSCT) compared with the Swedish population. Methods: The risk of osteoporotic fractures was determined in a retrospective population cohort study of adult (≥ 18 years) Swedish patients (n = 8463), who were transplanted with HSCT 1997–2016 and compared with all adults living in Sweden during the same period. Results: In the total study group (n = 8463), 90 hip fractures (1.1% both in males and females) and 361 major osteoporotic fractures (MOF) (3.2% in men and 6.0% in women) were identified. In the total study population, the ratio of observed and expected number of hip fracture for women was 1.99 (95% CI 1.39–2.75) and for men 2.54 (95% CI 1.91–3.31). The corresponding ratio for MOF in women was 1.36 (CI 1.18–1.56) and for men 1.61 (CI 1.37–1.88). From 2005 onwards, when differentiation in the registry between allo- and auto-HSCT was possible, the observed number of hip fracture and MOF in allo-HSCT (n = 1865) were significantly increased (observed/expected hip fracture 5.24 (95% CI 3.28–7.93) and observed/expected MOF 2.08 (95% CI 1.63–2.62)). Fractures occurred in mean 2.7 (hip) and 2.5 (MOF) years after allo-HSCT. Graft-versus-host disease (GVHD) was not associated with an increased risk of fracture. Conclusion: Patients who underwent HSCT had an increased risk of both hip and major osteoporotic fracture compared with the Swedish population and occurred in 4.3% of patients. GVHD was not statistically significantly associated with fracture risk. [ABSTRACT FROM AUTHOR]

Summary: Our study examined associations of the CXC motif chemokine ligand 9 (CXCL9), a pro-inflammatory protein implicated in age-related inflammation, with musculoskeletal function in elderly men. We found in certain outcomes both cross-sectional and longitudinal significant associations of CXCL9 with poorer musculoskeletal function and increased mortality in older men. This requires further investigation. Purpose: We aim to determine the relationship of (CXCL9), a pro-inflammatory protein implicated in age-related inflammation, with both cross-sectional and longitudinal musculoskeletal outcomes and mortality in older men. Methods: A random sample from the Osteoporotic Fractures in Men (MrOS) Study cohort (N = 300) was chosen for study subjects that had attended the third and fourth clinic visits, and data was available for major musculoskeletal outcomes (6 m walking speed, chair stands), hip bone mineral density (BMD), major osteoporotic fracture, mortality, and serum inflammatory markers. Serum levels of CXCL9 were measured by ELISA, and the associations with musculoskeletal outcomes were assessed by linear regression and fractures and mortality with Cox proportional hazards models. Results: The mean CXCL9 level of study participants (79.1 ± 5.3 years) was 196.9 ± 135.2 pg/ml. There were significant differences for 6 m walking speed, chair stands, physical activity scores, and history of falls in the past year across the quartiles of CXCL9. However, higher CXCL9 was only significantly associated with changes in chair stands (β = − 1.098, p < 0.001) even after adjustment for multiple covariates. No significant associations were observed between CXCL9 and major osteoporotic fracture or hip BMD changes. The risk of mortality increased with increasing CXCL9 (hazard ratio quartile (Q)4 vs Q1 1.98, 95% confidence interval 1.25–3.14; p for trend < 0.001). Conclusions: Greater serum levels of CXCL9 were significantly associated with a decline in chair stands and increased mortality. Additional studies with a larger sample size are needed to confirm our findings. [ABSTRACT FROM AUTHOR]

Summary: Patients who sustain fragility fractures prior to total shoulder arthroplasty have significantly higher risk for bone health-related complications within 8 years of procedure. Identification of these high-risk patients with an emphasis on preoperative, intraoperative, and postoperative bone health optimization may help minimize these preventable complications. Purpose: As the population ages, more patients with osteoporosis are undergoing total shoulder arthroplasty (TSA), including those who have sustained a prior fragility fracture. Sustaining a fragility fracture before TSA has been associated with increased risk of short-term revision rates, periprosthetic fracture (PPF), and secondary fragility fractures but long-term implant survivorship in this patient population is unknown. Therefore, the purpose of this study was to characterize the association of prior fragility fractures with 8-year risks of revision TSA, periprosthetic fracture, and secondary fragility fracture. Methods: Patients aged 50 years and older who underwent TSA were identified in a large national database. Patients were stratified based on whether they sustained a fragility fracture within 3 years prior to TSA. Patients who had a prior fragility fracture (7631) were matched 1:1 to patients who did not based on age, gender, Charlson Comorbidity Index (CCI), smoking, obesity, diabetes mellitus, and alcohol use. Kaplan–Meier and Cox Proportional Hazards analyses were used to observe the cumulative incidences of all-cause revision, periprosthetic fracture, and secondary fragility fracture within 8 years of index surgery. Results: The 8-year cumulative incidence of revision TSA (5.7% vs. 4.1%), periprosthetic fracture (3.8% vs. 1.4%), and secondary fragility fracture (46.5% vs. 10.1%) were significantly higher for those who had a prior fragility fracture when compared to those who did not. On multivariable analysis, a prior fragility fracture was associated with higher risks of revision (hazard ratio [HR], 1.48; 95% confidence interval [CI], 1.24–1.74; p < 0.001), periprosthetic fracture (HR, 2.98; 95% CI, 2.18–4.07; p < 0.001) and secondary fragility fracture (HR, 8.39; 95% CI, 7.62–9.24; p < 0.001). Conclusions: Prior fragility fracture was a significant risk factor for revision, periprosthetic fracture, and secondary fragility fracture within 8 years of primary TSA. Identification of these high-risk patients with an emphasis on preoperative and postoperative bone health optimization may help minimize these complications. Level of Evidence: III.

Summary: We conducted a retrospective cohort analysis to examine the association between hemoglobin (Hb) levels and refracture risk in elderly patients with osteoporotic fractures (OPFs). Our findings suggest a nonlinear relationship exists in females, and females with Hb levels below 10.7 g/dL may be at a higher risk of refracture. Introduction: Hematopoiesis and bone health have a reciprocal influence on each other. Nevertheless, there is a scarcity of in-depth research on the association between Hb levels and the occurrence of fractures. The present research aimed to investigate the correlation between Hb levels and the rate of refracture within 5 years among individuals with OPFs. Methods: A retrospective cohort analysis was undertaken between 2017 and 2022. The study included 1906 individuals who were inhabitants of Kunshan and were over 60 years old. These individuals had experienced an OPF between January 1, 2017, and July 27, 2022, resulting in their hospitalization. Cox proportional hazard regression models were used to evaluate the risk of refracture within 5 years based on the Hb levels acquired during the admission examination, with consideration for sex differences. A nonlinear relationship was identified using smoothed curve fitting and threshold analysis. Kaplan–Meier curves were used to compare refracture rates between patients with low and high Hb levels. Results: Elderly female patients with OPFs and lower Hb levels exhibited a significantly higher risk of a 5-year refracture. Conversely, no significant associations were observed between the two variables in male patients. A nonlinear correlation was found between Hb levels and the probability of refracture in females, with a turning point identified at 10.7 g/dL of Hb levels. A strong negative association was observed with the five-year refracture rate when Hb levels fell below 10.7 g/dL (hazard ratio (HR) = 0.63; 95% confidence interval (CI) 0.48 to 0.83; P-value = 0.0008). This finding suggests that for every 1 g/dL increase in Hb below 10.7 g/dL, the risk of refracture reduced by 37%. However, no statistically significant association was observed when Hb levels were above 10.7 g/dL. Conclusions: The findings demonstrated a significant negative correlation between Hb levels and the likelihood of refracture in elderly female patients with OPFs and suggested that elderly females with recent OPFs and Hb levels below 10.7 g/dL may be at a higher risk of refracture. Additionally, the Hb levels can serve as an indicator of bone fragility in elderly female patients with OPFs. These findings highlight the importance of monitoring Hb levels as a part of comprehensive management strategies to both assess skeletal health and prevent refractures in this population.

Aim: This retrospective study aimed to evaluate surgical outcomes and identify influential factors in pediatric femoral neck fractures. Materials and methods: A total of 25 hips from 23 pediatric patients who underwent surgical intervention for femoral neck fractures were included. Data encompassing patient demographics, fracture types, surgical techniques, complications, and follow-up outcomes were analyzed retrospectively. Factors such as fracture displacement, timing of surgery, fixation methods, and reduction quality were assessed concerning postoperative complications. Results: Falling from a height accounted for 48% of the trauma mechanisms, and avascular necrosis (AVN) was the most prevalent complication (4 hips). Although fracture displacement, bad reduction quality, and delayed surgery were more common among complicated cases, statistical significance was not attained. The study noted an association between presence of avascular necrosis and worse clinical results(rho: 0.428, p: 0.05, CI: 95%). Conclusion: Surgical treatment yielded favorable clinical outcomes; however, limitations due to the study's retrospective design, limited sample size, and single-center approach underscore the necessity for larger multicenter studies. Our findings emphasize the need for comprehensive investigations to better understand and manage pediatric femoral neck fractures, especially regarding factors influencing AVN and long-term outcomes.

Purpose: This study evaluates whether the fracture level alters the outcomes of minimally invasive hybrid stabilization (MIHS) with double-threaded, uncemented polyaxial screws for unstable osteoporotic vertebral fractures. Methods: This prospective cohort study included 73 patients (71.23% females, mean age: 79.9 ± 8.8 years) with unstable OF 3–4 fractures treated by MIHS between Nov 2015-Jan 2018. Patient characteristics, operative data, clinical outcomes, complications, radiological outcomes, and midterm (24-month) follow-up regarding functionality, pain, and quality of life were analyzed. Results: Patients had thoracolumbar (71.23%), thoracic (10.97%), and lumbar (17.8%) fractures. Operative time was < 120 min in 73.97% of patients, with blood loss < 500 ml in 97.25% of cases. No in-hospital mortality was recorded. Spine-associated complications occurred in 15.07% of patients, while 36.98% of patients had urinary tract infections (n = 12), pneumonia (n = 5), and electrolyte disturbances (n = 9). The mean length of hospital stay was 13.38 ± 7.20 days. Clinically-relevant screw loosening occurred in 1.7% of screws, and secondary adjacent fractures were diagnosed in 5.48% of patients. The alpha-angle improved significantly postoperatively (mean change: 5.4°) and remained stable for 24 months. The beta-angle improved significantly from 16.3° ± 7.5 to 10.8° ± 5.6 postoperatively but increased slightly to 14.1° ± 6.2 at midterm follow-up. Although no differences were seen regarding baseline data, clinical outcomes, and complications, fracture level significantly altered the COMI score at 24 months with no effect on pain score or quality-of-life. Conclusion: MIHS using polyaxial screws is a safe treatment for single-level osteoporotic spinal fractures. Fracture level did not alter radiological reduction loss; however, it significantly altered patients' function at 24 months. [ABSTRACT FROM AUTHOR]

The purpose of this study was to evaluate pre- and post-fracture medical management of osteoporosis among patients who underwent surgical fixation of femoral neck fractures (FNF) and vertebral compression fractures (VCF), and to investigate if there is a difference in treatment, management, and subsequent fractures between FNF and VCF patients. Patients who underwent surgical fixation of FNF or VCF were retrospectively reviewed at a minimum 1 year follow up. Patients were excluded if their fracture was caused by high energy trauma or malignancy, <50 years-old, deceased, or lost to follow up. Patient demographics such as age, sex, BMI, American Society of Anesthesiology Physical Status Classification System and Charleston Comorbidity index were recorded. Management of osteoporosis, including medication regimen and dual-energy X-ray absorptiometry (DEXA) scans were assessed preoperatively and at minimum one year follow up. Subsequent fractures were also recorded. In the analysis of 370 patients (74.7% FNF, 25.2% VCF), demographics showed a predominantly female population (mean age 78.1). Preoperatively, 21.6% were diagnosed with osteoporosis, consistent between FNF and VCF. Postoperatively, there were no significant differences in new osteoporosis diagnoses, bisphosphonate use, or subsequent fractures. VCF patients, however, were more likely to receive denosumab and post-operative DEXA scans (p < 0.05). Within a year, 6.2% experienced subsequent fractures, with no significant FNF-VCF difference. Only 12.7% received appropriate post-operative osteoporosis treatment, 27.1% had DEXA scans, and 25% had a recorded osteoporosis diagnosis. Multivariable analysis highlighted pre-fracture osteoporosis diagnosis as the sole predictor for post-operative DEXA scans and anti-osteoporotic medication (p < 0.001). This study suggests that factors beyond the type of fragility fracture may influence subsequent fracture risk and anti-osteoporotic medication administration in elderly patients. These findings underscore the importance of a comprehensive approach to fracture risk assessment and treatment decisions in this population. III. [ABSTRACT FROM AUTHOR]

Background: Severe trauma is the leading cause of disability and mortality in the patients under 35 years of age. Surgical site infections (SSI) represent a significant complication in this patient population. However, they are often inadequately investigated, potentially impacting the quality of patient outcomes. The aim of this study was to investigate the epidemiology of SSI and risk factors in severe trauma patients. Methods: We conducted a multicenter retrospective cohort study screening the severe trauma patients (STP) admitted to two intensive care units of an academic institution in Marseille between years2018 and 2019. Those who underwent orthopedic or spinal surgery within 5 days after admission were included and classified into two groups according to the occurrence of SSI (defined by the Centers for Disease Control (CDC) international diagnostic criteria) or not. Our secondary goal was to evaluate STP survival at 48 months, risk factors for SSI and microbiological features of SSI. Results: Forty-seven (23%) out of 207 STP developed an SSI. Mortality at 48-months did not differ between SSI and non-SSI patients (12.7% vs. 10.0%; p = 0.59). The fractures of 22 (47%) severe trauma patients with SSI were classified as Cauchoix 3 grade and 18 (38%) SSI were associated with the need for external fixators. Thirty (64%) severe trauma patients with SSI had polymicrobial infection, including 34 (72%) due to Gram-positive cocci. Empirical antibiotic therapy was effective in 31 (66%) cases. Multivariate analysis revealed that risk factors such as low hemoglobin, arterial oxygenation levels, hyperlactatemia, high serum creatinine and glycemia, and Cauchoix 3 grade on the day of surgery were associated with SSI in severe trauma patients. The generated predictive model showed a good prognosis performance with an AUC of 0.80 [0.73–0.88] and a high NPV of 95.9 [88.6–98.5] %. Conclusions: Our study found a high rate of SSI in severe trauma patients, although SSI was not associated with 48-month mortality. Several modifiable risk factors for SSI may be effectively managed through enhanced perioperative monitoring and the implementation of a patient blood management strategy. [ABSTRACT FROM AUTHOR]

Myasthenia gravis (MG) patients often require long-term glucocorticoid therapy, which may affect bone health. This study aimed to assess long-term changes in bone mineral density (BMD), evaluate osteoporotic fracture incidence, and examine the relationship between MG-specific factors and bone health outcomes over a 10-year period. This single-center, prospective cohort study included 28 MG patients. BMD, T-scores, Z-scores, and bone turnover markers were measured at baseline. FRAX® scores were calculated and adjusted for glucocorticoid dose. Fracture occurrence was monitored for over 10 years. Five (17.9%) patients experienced major osteoporotic fractures during follow-up. The fracture group had significantly lower baseline BMD and T-scores than the no-fracture group. Baseline FRAX® scores for major osteoporotic fracture risk were significantly higher in the fracture group (median 19.0% vs. 5.7%, p = 0.001). The fracture group progressed from osteopenia at baseline to osteoporosis by the end of this study. This study highlights the importance of early and regular bone health assessments in MG patients, particularly those receiving long-term glucocorticoid therapy. The FRAX® tool may be valuable for fracture risk stratification in this population. These findings can inform clinical practice and improve long-term management strategies for MG patients who are at risk of osteoporotic fractures. [ABSTRACT FROM AUTHOR]

Bioactive glass synthetic bone grafts are used to treat osseous defects in orthopaedic surgery. Characterization of the clinical scenarios associated with bioactive glass use in the context of orthopaedic trauma, are not well established. This study aims to characterize population demographics, operative variables, as well as postoperative variables, for patients who required bone grafting for treatment of traumatic orthopaedic injuries and received a bioactive glass bone substitute intraoperatively. The electronic medical record at a large Level I trauma center was queried for fracture patients between January 1st, 2019, and April 30th, 2022. Our retrospective cohort included fracture patients who received Fibergraft Matrix or Fibergraft Putty intraoperatively, and their respective control groups. This study ascertained patient demographic variables, operative variables, and postoperative variables. Differences in categorical variables were tested with Fischer's Exact Tests, while differences in continuous variables were tested with ANOVA. Statistical significance was determined as P < 0.05. If the overall Group model was significant for a given variable, post-hoc Fischer's Exact or Tukey HSD tests were used to assess pairwise significance between individual Group pairs. A total of four categories across our analysis of demographic, operative, and postoperative variables displayed significant differences amongst subject Groups (P ≤ 0.03). Individual groups were compared such that significant differences between subject groups could be appreciated for a specific variable. FM subjects had greater length of surgery, billable costs, and vitamin D supplementation at the time of surgery compared to FM controls. Similarly, FP subjects had greater length of surgery, billable cost, and implants used intraoperatively compared to FP controls. This analysis revealed Fibergraft patients to have greater length of surgery and billable cost, with respect to their matched controls. These data suggest that Fibergraft patients had more severe orthopaedic fractures compared to matched controls. [ABSTRACT FROM AUTHOR]

Introduction: Increasing incidence of fragility fractures has spurred development of protocols, largely focused on peri-operative care, with numerous proven benefits. The purpose of this investigation was to evaluate outcomes of our hip fracture treatment program regarding successful protocol implementation, compliance, effect on subsequent fracture rates, and mortality during the first decade of adoption. Methods: A retrospective review identified patients >65 years old with fragility hip fractures between 2010 and 2022. The HiROC (+) cohort consisted of patients who received a "High-Risk Osteoporosis Clinic" (HiROC) referral for bone health evaluation and bisphosphonate initiation as indicated. Additional fracture rates and mortality at 3 years were calculated. Protocol implementation and compliance over the first 10 years was analyzed in the four identified cohorts. Results: A total of 1671 fragility hip fractures were identified, with 386 excluded due to insufficient follow-up, with an average age of 81.6 years and a median follow-up of 36.4 months. Of the 1280 included cases, 56% (n = 717) had a HiROC referral placed. HiROC(+) groups had lower subsequent fracture rates at two years, compared to those without referral (28% vs 13%, P < 0.0001) and those completing more steps of the protocol had lower subsequent fracture rates (28% vs 15% vs 13% vs 5%, P < 0.0001). No statistically significant difference was observed between the cohorts for anatomic site of subsequent fractures. Discussion: Greater than half of all eligible patients were successfully captured by the protocol. Patients completing more steps of the protocol had lower subsequent fracture rates. Captured patients demonstrated reduced mortality rates when compared to current literature. Conclusion: Successful implementation of this geriatric hip fracture protocol was associated with reduced additional fractures and mortality rates. Identifying steps of process failures in the protocol can provide opportunities for increased compliance and reduction in future fracture occurrences. [ABSTRACT FROM AUTHOR]

Methods: Due to demographic change, the number of polytraumatized geriatric patients (> 64 years) is expected to further increase in the coming years. In addition to the particularities of the accident and the associated injury patterns, prolonged inpatient stays are regularly observed in this group. The aim of the evaluation is to identify further factors that cause prolonged inpatient stays. A study of the data from the TraumaRegister DGU® from 2016–2020 was performed. Inclusion criteria were an age of over 64 years, intensive care treatment in the GAS-region, and an Injury Severity Score (ISS) of at least 16 points. All patients who were above the 80th percentile for the average length of stay or average intensive care stay of the study population were defined as so-called long-stay patients. This resulted in a prolonged inpatient stay of > 25 days and an intensive care stay of > 13 days. Among other, the influence of the cause of the accident, injury patterns according to body regions, the occurrence of complications, and the influence of numerous clinical parameters were examined. Results: A total of 23,026 patients with a mean age of 76.6 years and a mean ISS of 24 points were included. Mean ICU length of stay was 11 ± 12.9 days (regular length of stay: 3.9 ± 3.1d vs. prolonged length of stay: 12.8 ± 5.7d) and mean inpatient stay was 22.5 ± 18.9 days (regular length of stay: 20.7 ± 15d vs. 35.7 ± 22.3d). A total of n = 6,447 patients met the criteria for a prolonged length of stay. Among these, patients had one more diagnosis on average (4.6 vs. 5.8 diagnoses) and had a higher ISS (21.8 ± 6 pts. vs. 26.9 ± 9.5 pts.) Independent risk factors for prolonged length of stay were intubation duration greater than 6 days (30-fold increased risk), occurrence of sepsis (4x), attempted suicide (3x), presence of extremity injury (2.3x), occurrence of a thromboembolic event (2.7x), and administration of red blood cell concentrates in the resuscitation room (1.9x). Conclusions: The present analysis identified numerous independent risk factors for significantly prolonged hospitalization of the geriatric polytraumatized patient, which should be given increased attention during treatment. In particular, the need for a smooth transition to psychiatric follow-up treatment or patient-adapted rehabilitative care for geriatric patients with prolonged immobility after extremity injuries is emphasized by these results.

Purpose: The primary objective of this study was to investigate the association between preoperative chronic steroid use and postoperative complications following open reduction internal fixation (ORIF) for proximal humerus fractures (PHF). Methods: The American College of Surgeons National Surgical Quality Improvement (ACS-NSQIP) database was queried for all patients who underwent PHF ORIF between 2015 and 2021. A total of 6,273 patients were included in this study, of which 3.4% (n = 212) were in the chronic steroid use cohort. Patient characteristics including demographics, comorbidities, and 30-day postoperative complications after PHF ORIF were collected. Bivariate logistic regression and multivariate logistic regression analysis, adjusted for all significantly associated variables, was conducted to investigate the relationship between preoperative chronic steroid use and postoperative complications. Results: Chronic steroid use was significantly associated with age ≥ 75 (p < 0.001), male gender (p =0.006), dependent functional status (p = 0.008), American Society of Anesthesiologist (ASA) ≥ 3 (p < 0.001), CHF (p = 0.007), hypertension (p < 0.001), COPD (p < 0.001), bleeding disorder (p = 0.007), ascites (p = 0.040), disseminated cancer (p< 0.001), and systemic sepsis (p < 0.001). After adjusting for all significantly associated variables, chronic steroid use was independently associated with major complication (OR 1.60, 95% CI 1.06–2.43; p = 0.026), and non-home discharge (OR 1.05, 95% CI 1.01–1.08; p = 0.014). Conclusion: Preoperative chronic steroid use is associated with increasing rate of postoperative complications following PHF ORIF. Better understanding and characterizing chronic steroid use as a preoperative risk factor can aid physicians in risk stratification to reduce rates of postoperative complications following PHF ORIF.

Study Design: A post-hoc analysis of a prospective cohort study. Purpose: This study aimed to identify factors at the time of injury associated with declining activities of daily living (ADLs) in the chronic phase of osteoporotic vertebral fractures (OVFs) managed conservatively. Overview of Literature: Although a conservative approach is the treatment of choice for OVFs, ADLs do not improve or eventually decrease in some cases. However, the risk factors for ADL decline after the occurrence of OVFs, particularly the difference between those with or without initial bed rest, are unknown. Methods: A total of 224 consecutive patients with OVFs aged ≥65 years who received treatment within 2 weeks after the occurrence of injury were enrolled. The patients were followed up for 6 months thereafter. The criteria for evaluating the degree of independence were applied to evaluate ADLs. Multivariable analysis with a logistic regression model was performed to evaluate the risk factors for ADL decline. Results: In total, 49/224 patients (21.9%) showed a decline in ADLs. Of these, 23/116 patients (19.8%) in the rest group and 26/108 patients (24.1%) in the no-rest group experienced a decline in ADLs. In the logistic regression analyses, a diffuse low signal on T2-weighted magnetic resonance imaging (MRI) (odds ratio, 5.78; 95% confidence interval, 2.09–16.0; p=0.0007) and vertebral instability (odds ratio, 3.89; 95% confidence interval, 1.32–11.4; p=0.0135) were identified as independent factors in the rest and no-rest groups, respectively. Conclusions: In patients with acute OVFs, a diffuse low signal on T2-weighted MRI and severe vertebral instability were independently associated with ADL decline in patients treated with and without initial bed rest, respectively.

Summary: The refracture rate after major trauma is approximately half (57%) the refracture rate after a minimal trauma injury. Extending Fracture Liaison Service activity to include major trauma patients creates significant additional direct cost, but remains essentially cost neutral if notional savings through refracture risk reduction are taken into account. Purpose: To compare the 3-year refracture rate following minimal trauma (MT) and non-minimal trauma (non-MT) injuries and evaluate the cost of extending fracture liaison service (FLS) operations to non-MT presentations. Methods: Patients aged 50, or above presenting to the John Hunter Hospital with a fracture in calendar year 2018 were identified through the Integrated Patient Management System (IPMS) of the Hunter New England Health Service's (HNEHS), and re-presentation to any HNEHS facility over the following 3 years monitored. The refracture rate of MT and non-MT presentations was compared and analysed using Cox proportional hazards regression models. The cost of including non-MT patients was estimated through the use of a previously conducted micro-costing analysis. The operational fidelity of the FLS to the previous estimate was confirmed by comparing the 3-year refracture rate of MT presentations in the two studies. Results: The 3-year refracture rate following a MT injury was 8% and after non-MT injury 4.5%. Extension of FLS activities to include non-MT patients in 2022 would have cost an additional $198,326 AUD with a notional loss/saving of $ − 26,625/ + 26,913 AUD through refracture risk reduction. No clinically available characteristic at presentation predictive of increased refracture risk was identified. Conclusion: The 3-year refracture after a non-MT injury is about half (57%) that of the refracture rate after a MT injury. Extending FLS activity to non-MT patients incurs a significant additional direct cost but remains cost neutral if notional savings gained through reduction in refracture risk are taken into account.

Introduction: Long bone fractures (LBF) often cause severe pain, impacting patients' quality of life. This prospective, randomized, double-blind study aimed to compare the analgesic efficacy of dexketoprofen (Dex) and ibuprofen (Ibu) in LBF patients in the emergency department. Methods: Conducted between August 10, 2023, and January 17, 2024, the study included 100 eligible patients randomized into Dex and Ibu groups. Visual analog scale (VAS) scores were measured at baseline and at 30, 60, and 120 min. DeltaVAS (ΔVAS) values and ΔVAS percentages (ΔVAS%) were calculated. Primary endpoints were ΔVAS scores (ΔVAS 30-60-120) and ΔVAS% for comparative analysis. Results: Statistical analysis showed no significant difference in ΔVAS30 (p = 0.359). However, ΔVAS60 exhibited a significant difference (p = 0.027), as did ΔVAS120 (p = < 0.001). ΔVAS%30 showed no significance (p = 0.224), but ΔVAS%60 and ΔVAS%120 were clinically and statistically significant (p = 0.017 and p = < 0.001, respectively). Conclusion: Ibuprofen 800 mg demonstrated superior analgesic efficacy at 60 and 120 min compared to Dex in long bone fractures. These findings suggest ibuprofen's potential as an effective pain management option in emergency departments. [ABSTRACT FROM AUTHOR]

Purpose: Fracture-Related Infection (FRI) is associated with high medical costs and prolonged healthcare utilization. However, limited data is available on the financial impact. The purpose of this study was to investigate the impact of FRI on direct hospital costs and healthcare utilization. Methods: This was a retrospective cohort study in a level-1 trauma centre in the Netherlands. Patients ≥ 18 years, after open reduction and internal fixation of a long bone fracture between January 1st 2016 and November 1st 2021, were included. Exclusion criteria were Injury Severity Score (ISS) ≥ 16, indefinable data on costs or incomplete follow-up. Hospital costs related to fracture treatment were individually calculated based on procedure codes raised with a fixed percentage of overhead expenses, in line with hospital billing policies. Results: In total, 246 patients were included with a median follow-up of 1 year (IQR 0.6–1.8). A total of 45 patients developed FRI, of whom 15 patients had an FRI recurrence. Compared to non-FRI patients, median hospital costs from an FRI patient without and with recurrence, were respectively three (3.1) and seven (7.6) times higher. Compared to non-FRI patients, increased costs in patients with FRI or recurrent FRI are due to respectively a fivefold or even tenfold prolonged length-of-stay, two or seven additional infection-related surgeries, and 21 or 55 days of intravenous antibiotic treatment. Conclusion: Direct healthcare costs of patients with single occurrence of FRI after long bone fracture treatment are three times higher compared to non-FRI patients. In case of FRI-recurrence, the differences in costs might even increase to sevenfold. To put this in perspective, cost of severely injured trauma patients were recently established at approximately 25.000 euros. Compared to non-FRI patients, increased costs in patients with FRI or recurrent FRI are due to respectively a fivefold or even tenfold prolonged length-of-stay, two or seven additional infection-related surgeries and 21 or 55 days of intravenous antibiotic treatment. Not only from patient perspective but also from a financial aspect, it is important to focus on prevention of (recurrent) FRI. [ABSTRACT FROM AUTHOR]

Introduction: Low-energy fragility fractures of the pelvis (FFP) are an underestimated entity, yet increasing in incidence. The bleeding risk for pelvic fractures in high-energy trauma is well known, resulting in adequate treatment guidelines and clear protocols. This is not the case for FFPs but this risk is presumably low. This study aims to investigate the clinically relevant bleeding risk, in patients older than 50 years with a fragility fracture of the pelvis admitted to the emergency department (ED). Method: A retrospective cohort study was conducted of consecutive patients aged over 50 years with a FFP due to low-energy trauma (LET) presented to the ED of a single trauma center (North-West Clinics in Alkmaar, The Netherlands) between January 2018 and August 2022. The primary outcome was the percentage of patients requiring blood transfusion, or invasive procedures such as coiling by the interventional radiologists or damage control surgery, due to bleeding. Secondary outcomes were the mean decrease of hemoglobin and mortality. Results: In total, 322 consecutive patients with a mean age of 80 years of which 84% female were included. In total 66% was admitted to the hospital and seven patients underwent surgical intervention. Three cases (0.9%) of potentially clinically relevant bleeding were observed. These three cases needed a blood transfusion, without other interventions, and were all admitted with a low hemoglobin level without signs of hemodynamic instability. No invasive interventions were noted. Conclusion: The risk of bleeding in FFP's is very low with very few patients requiring blood transfusions (< 1%) and with no invasive interventions due to bleeding. Since the risk of clinically relevant bleeding is low, the significance of repeated Hb checks and CECT may be questionable. The effect of these diagnostics in case of absence of hemodynamic instability and above borderline normal Hb levels needs to be investigated in further studies. [ABSTRACT FROM AUTHOR]

Opioid dependence has become a public health problem in several countries. A cohort study was used to assess first-time dispensed opioids, in 2012–2015, by drug type, doses, oral morphine equivalents, and diagnoses, in Sweden. First-time opioid users aged 18–64 years, previously cancer-free and opioid-naïve for at least 6.5 years, were studied. Time trends in opioid use in Sweden 2006–2021 were also studied. During the study, 617,568 patients were dispensed opioids for the first time. The crude proportion of first-time opioid users in the population was 2.7% in 2012 and 2.6% in 2015. The combination product of codeine and paracetamol was the most frequent dispensed opioid with 322,818 patients (52.3%), followed by tramadol (120,271, 19.6%) and oxycodone (104,418, 16.9%). From 2012 to 2015, tramadol as first dispensed opioid dropped from 26.5% to 13.7% and oxycodone increased from 10.0% to 24.4%. For the four most commonly dispensed opioids, the median initial dispensal ranged from 250 to 400 oral morphine equivalents. The most common indication was fracture of the lower leg during inpatient care and back pain for specialized outpatient care. Trends in dispensed opioids in Sweden show a shift from tramadol to oxycodone, but do not show an increase in total opioid use. [ABSTRACT FROM AUTHOR]

Background: Perilunate dislocations and perilunate fracture dislocations (PLD/PLFDs) are rare injuries of the wrist, with surgical management leading to acceptable functional results. Purpose: The purpose of this study was to assess the functional outcomes of the patients of our department who were treated with surgical management of PLDs/PLFDs through dorsal approach, as well as to report any complications on their follow-up. Patients and methods: In this retrospective study, 52 patients with PLD/PLFD, fulfilling the inclusion and exclusion criteria of the study, underwent surgical management of their injury. All patients were followed up at 6 weeks, 12 weeks, 6 months, 1 year postoperatively with radiographic imaging as well as functional scores measured with the modified mayo wrist score and the QuickDASH questionnaire. Results: The mean postoperative modified Mayo score was 76.8 ± 8.8 and the mean QuickDASH score was 1.52 ± 2.18. Of the 52 cases, 20% had excellent results, 42% had good results, 29% had fair results and 9% had poor results as per the modified Mayo wrist score. No patient signed any symptoms of median nerve neuropathy. Conclusion: In conclusion, open reduction and internal fixation through dorsal approach is a reliable technique to manage perilunate injuries in spite of radiological evidence of wrist arthritis, as it also provides consistently good results in terms of functional outcomes. Level of evidence IV: Retrospective case series study. [ABSTRACT FROM AUTHOR]

Introduction: Ceramic-on-ceramic bearings have been widely used since their introduction in the 1970s. First-generation ceramics have very high fracture (breakage) rates. To overcome this, in the 1990s, modular cotyloid insert designs were developed, consisting of a ceramic and polyethylene composite (sandwich-type) liner; however, high implant fracture rates were observed in the medium term. We aimed to estimate the cumulative incidences of revision surgery (implant failure) and implant failure due to fractures, survival rates (time-to-revision surgery and time-to-fracture), and the long-term clinical and radiological outcomes in our series. Methods: This was an observational, longitudinal, ambispective, single-centre study based on patients who underwent primary total hip arthroplasty (THA) using a sandwich-type liner (Cerasul), only available in our tertiary hospital between January 1999 and December 2002. Cumulative incidences were estimated and the 95% confidence interval (95% CI) was calculated. The Kaplan-Meier method was used to assess the time-to-revision surgery and time-to-fracture. Results: 54 patients (49 men) were included, accounting for 59 sandwich-type linear implants. The mean (range) age was 47.4 (22–57) years. The primary THA indications were osteoarthritis (28 patients), osteonecrosis (14), childhood pathology sequelae (11), and inflammatory arthritis (6). The cumulative incidence of revision surgery by implants was 8.5% (5/59, 95% CI, 3.5–19.2%), 9.3% by patients (5/54, 95% CI, 4.0–19.9%), and 5.1% by implant fractures (3/59, 95%CI, 1.7–13.9%). The median (Interquartile Range, IQR) time-to-revision surgery was 158 (72.5–161) months, and the time to fracture was 182 (138–215) months. All primary THAs had good clinical and long-term survival outcomes. All implants had signs of solid fixation. Conclusions: After a 20-year follow-up period, the polyethylene-ceramic sandwich-type liner showed a long survival rate and low cumulative incidence of implant fracture; however, implant fractures remain the main complication. Orthopaedic surgeons should be aware that some patients still have this type of prosthesis and must be capable of responding quickly if a fracture occurs. [ABSTRACT FROM AUTHOR]

Summary: This 5-year longitudinal study investigated the relationship between depressive symptoms and fracture risk in a large Japanese cohort. Depressive symptoms were a significant risk factor for hip fractures in women. Purpose: A relationship between depressive symptoms and fractures has not been clearly demonstrated. We aimed to investigate the relationship between depressive symptoms and 5-year fracture risk in the Japan Public Health Center-based Prospective Study for the Next Generation. Methods: From 2011 to 2016, 114,092 participants were enrolled, and a follow-up survey was conducted 5 years later. We analyzed 30,552 men and 38,063 women aged 40–74 years who had no past fractures at baseline. Presence of depressive symptoms was defined as a modified 11-item Center for Epidemiological Studies Depression Scale score of 8 or higher, a history of depression, or use of antidepressants. Subjects were asked to report vertebral, upper limb, and/or hip fractures, except for traffic or work accidents, that occurred during the follow-up period. The adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for fracture were analyzed via logistic regression analysis to evaluate the relationship between depressive symptoms and fracture. Results: Women with depressive symptoms demonstrated a high AOR for hip fractures (AOR: 2.78, 95% CI: 1.30 – 5.92); this result was consistent in post menopause women. In men, this association was not found for any age group or any type of fracture. Conclusions: Depressive symptoms in women may increase the risk of hip fractures. Further studies are required to explore this relationship in more detail. [ABSTRACT FROM AUTHOR]

Purpose: To study the prevalence of osteoporosis, falls and fractures in adults with ischaemic stroke. Methods: Observational cohort study of adults aged ≥ 50 years admitted with ischaemic stroke over a 12-month period were invited to participate in a telephone interview one-year post-stroke to ascertain falls and fracture. A Fracture Risk After Ischaemic Stroke (FRAC-stroke) score was calculated. Results: Of the 1267 patients admitted to the stroke unit between 1 January 2020 and 31 December 2020, 624 had a modified Rankin Score documented. Of these, 316 adults ≥ 50 years had ischaemic stroke and 131 consented to a telephone interview. Mean age was 72.4 ± 10.7 years and 36.6% were female. 34 patients (25.9%) had a FRAC-stroke score of ≥ 15, equating to ≥ 5% risk of fracture in the year following stroke. Eleven (8.4%) patients (6 female) had a minimal trauma fracture in the 12 months post-stroke. There was a significant difference in patients experiencing falls pre- and post-stroke (19.8% vs 31.3%, p = 0.04). FRAC-stroke score was higher in those who had a fracture post stroke compared those who did not (20.4 vs 8.9, p < 0.001). Receiver operating characteristic analysis found an area under the curve of 0.867 for FRAC-stroke score (95% CI 0.785–0.949, p < 0.005). The optimal cutoff value for FRAC-stroke score predicting fracture was 12 with a sensitivity of 90.9% and specificity of 70%. Conclusion: The FRAC-stroke score is a simple clinical tool that can be used to identify patients at high risk of fracture post-stroke who would most benefit from osteoporosis therapy. Summary: Stroke is a risk factor for fracture due to immobilisation, vitamin D deficiency and increased falls risk. This study found that a simple bedside tool, the FRAC-stroke score, can predict fracture after ischaemic stroke. This will allow clinicians to plan treatment of osteoporosis prior to discharge from a stroke unit. [ABSTRACT FROM AUTHOR]

Summary: There is imminent refracture risk in elderly individuals for up to six years, with a decline thereafter except in women below 75 who face a constant elevated risk. Elderly men with fractures face the highest mortality risk, particularly those with hip and vertebral fractures. Targeted monitoring and treatment strategies are recommended. Purpose: Current management and interventions for osteoporotic fractures typically focus on bone mineral density loss, resulting in suboptimal evaluation of fracture risk. The aim of the study is to understand the progression of fractures to refractures and mortality in the elderly using multi-state models to better target those at risk. Methods: This prospective, observational study analysed data from the AGES-Reykjavik cohort of Icelandic elderly, using multi-state models to analyse the evolution of fractures into refractures and mortality, and to estimate the probability of future events in subjects based on prognostic factors. Results: At baseline, 4778 older individuals aged 65 years and older were included. Elderly men, and elderly women above 80 years of age, had a distinct imminent refracture risk that lasted between 2–6 years, followed by a sharp decline. However, elderly women below 75 continued to maintain a nearly constant refracture risk profile for ten years. Hip (30–63%) and vertebral (24–55%) fractures carried the highest 5-year mortality burden for elderly men and women, regardless of age, and for elderly men over 80, lower leg fractures also posed a significant mortality risk. Conclusion: The risk of refracture significantly increases in the first six years following the initial fracture. Elderly women, who experience fractures at a younger age, should be closely monitored to address their long-term elevated refracture risk. Elderly men, especially those with hip and vertebral fractures, face substantial mortality risk and require prioritized monitoring and treatment. [ABSTRACT FROM AUTHOR]

Summary: A knowledge gap exists in associating later life's osteoporotic fracture and middle adulthood's BMI trajectories. We observed an association showing those transitioning from overweight to normal weight face a higher fracture risk in late adulthood, emphasizing the potential benefits of maintaining a stable BMI to reduce late-life fractures. Purpose: Numerous studies on the relationship between obesity and fractures have relied on body mass index (BMI) at a single time point, yielding inconclusive results. This study investigated the association of BMI trajectories over middle adulthood with fracture risk in late adulthood. Methods: This prospective cohort study analyzed 1772 qualified participants from the Framingham Original Cohort Study, with 292 (16.5%) incident fractures during an average of 17.1-year follow-up. We constructed BMI trajectories of age 35–64 years based on latent class mixed modeling and explored their association with the risk of fracture after 65 years using the Cox regression. Results: The result showed that compared to the BMI trajectory Group 4 (normal to slightly overweight; see "Methods" for detailed description), Group 1 (overweight declined to normal weight) had a higher all-fracture risk after age 65 (hazard ratio [HR], 2.22, 95% CI, 1.13–4.39). The secondary analysis focusing on lower extremity fractures (pelvis, hip, leg, and foot) showed a similar association pattern. Conclusions: This study suggested that people whose BMI slightly increased from normal weight to low-level overweight during 30 years of middle adulthood confer a significantly lower risk of fracture in later life than those whose BMI declined from overweight to normal weight. This result implies the potentially beneficial effects of avoiding weight loss to normal weight during middle adulthood for overweight persons, with reduced fracture risk in late life.

BACKGROUND: Vertebral fragility fractures (VFFs) commonly result from low bone mass and microarchitecture deterioration of bone tissue. spinal orthoses are common non-pharmacological options for managing vertebral fracture pain. However, the effects of spinal orthoses on pain, physical functioning, and quality of life (QoL) are still debated. OBJECTIVE: This survey aimed to investigate the patients-reported outcomes of a dynamic spinal orthosis prescribed in the routine clinical practice of VFFs management. METHODS: This multi-center national-wide prospective cohort study assessed older patients (aged > 60 years) diagnosed with acute VFFs and prescribed with a dynamic spinal orthosis (Spinfast®). A survey questionnaire was realized and included sections on patient characterization, osteoporosis characterization, spinal orthosis, clinical outcomes, pain medications, and osteoporosis medications. The questionnaire was administered at baseline and after three months. A total of 68 patients completed the questionnaire at three months. Most patients had one or two VFFs and were treated with pain medications and osteoporosis medications. Compliance and tolerability of the spinal orthosis were assessed, and clinical outcomes such as pain intensity, physical functioning, and QoL were measured. RESULTS: The results showed no significant differences in outcomes between age subgroups. Italian physical medicine and rehabilitation physicians were commonly involved in the management of VFFs patients. Sixty-six patients completed the questionnaire. The results showed that pain intensity, physical functioning and QoL improved after three months of spinal orthosis wearing (p < 0.0001). CONCLUSION: The correct management of VFFs is mandatory to improve pain and reduce disability, and our findings suggested a positive role of dynamic spinal orthosis to improve the comprehensive management of VFFs patients. However, high-quality research trials are warranted to provide clear recommendations for the correct clinical management of VFF. [ABSTRACT FROM AUTHOR]

Rationale Comorbidities are common in fracture patients, but the interaction between fracture and comorbidities remains unclear. This study aimed to define specific multimorbidity clusters in older adults and quantify the association between the multimorbidity clusters and fracture risk. Methods This nationwide cohort study includes 1.7 million adults in Denmark aged ≥50 years who were followed from 2001 through 2014 for an incident low-trauma fracture. Chronic diseases and fractures were identified from the Danish National Hospital Discharge Register. Latent class analysis and Cox's regression were conducted to define the clusters and quantify fracture risk, respectively. Results The study included 793 815 men (age: 64 ± 10) and 873 524 women (65.5 ± 11), with a third having ≥1 chronic disease. The pre-existent chronic diseases grouped individuals into low-multimorbidity (80.3% in men, 83.6% in women), cardiovascular (12.5%, 10.6%), malignant (4.1%, 3.8%), diabetic (2.4%, 2.0%) and hepatic clusters (0.7%, men only). These clusters distinguished individuals with advanced, complex, or late-stage disease from those having earlier-stage disease. During a median follow-up of 14 years (IQR: 6.5, 14), 95 372 men and 212 498 women sustained an incident fracture. The presence of multimorbidity was associated with a significantly greater risk of fracture, independent of age and sex. Importantly, the multimorbidity clusters had the highest discriminative performance in assessing fracture risk, whereas the strength of their association with fracture risk equalled or exceeded that of both the individual chronic diseases most prevalent in each cluster and of counts-based comorbidity indices. Conclusions Future fracture prevention strategies should take comorbidities into account. Multimorbidity clusters may provide greater insight into fracture risk than individual diseases or counts-based comorbidity indices. [ABSTRACT FROM AUTHOR]

Objective: To determine the association between the extent of mobilisation within the first postoperative day and 30-day mortality after hip fracture. Design: Cohort study Setting: Acute orthopaedic hospital ward Participants: Consecutive sample of 701 patients, 65 years of age or older, 80% from own home, 49% with a trochanteric fracture, and 61% with an American Society of Anesthesiology grade > 2. Intervention: n/a Main measures: Cumulated ambulation score (CAS) (0-6 points) on the first postoperative day and 30-day postoperative mortality. A CAS = 0 reflects no functional mobility (bedridden), while a CAS = 6 reflects independent out-of-bed-transfer, chair-stand, and indoor walking status. Results: Overall, 86% of patients were mobilised to standing or seated in chair (CAS ≥ 1) on the first postoperative day. A CAS of 0, 1–3, and 4–6 was observed for 97 (14%), 519 (74%), and 85 (12%) patients, respectively. Overall, 61 (8.7%) patients died within 30 days with the highest mortality (23.7%, n = 23) seen for those not mobilised (CAS = 0). Only one patient (1.2%) with a CAS of 4–6 points died. Cox regression analysis adjusted for age, sex, residential status, pre-fracture CAS, fracture type, and American Society of Anesthesiology grade, showed that a one-unit increase in CAS was associated with a 38% lower risk of 30-day mortality (Hazard Ratio = 0.63, 95%Confidence Interval, 0.50–0.78). Conclusion: Mobility on the first postoperative day was associated with 30-day postoperative mortality, with a lower risk observed for those completing greater mobility. National registries may consider extending collection of mobility on the first postoperative day from a binary indicator to the CAS which captures the extent of mobility achieved.

The physiological changes and alterations in gait following amputation may increase the risk of fractures. However, there is insufficient research on fracture risk in amputees. Therefore, this study intended to analyze whether the risk of new fractures increases after traumatic amputations. This population-based, retrospective cohort study used data from the Korean National Health Insurance System database. The study included 19,586 participants who had undergone an amputation and 76,645 matched controls. The incidence of any fracture and site-specific fractures (vertebral, hip, and others) according to amputation site(s) and severity of disability due to amputation were evaluated using Cox proportional hazard regression analysis. During the mean follow-up of 4.2 years, amputees had a higher incidence rate (IR) of any fracture (adjusted HR [aHR] 1.47, 95% CI 1.36–1.60), vertebral fracture (aHR 1.63, 95% CI 1.44–1.85), hip fracture (aHR 1.85, 95% CI 1.39–2.46), and other fracture (aHR 1.34, 95% CI 1.20–1.49) compared to that of controls. In the presence of disability, the risks were further increased and were highest among amputees with severe disabilities. All fracture risks were higher in amputees than they were in controls, regardless of lower limb or upper limb amputation. This cohort study demonstrated that traumatic amputees experienced higher incidence of all fractures than did individuals without amputations, and this risk increases with severity of disability. This finding underscores the importance of early screening and lifestyle interventions to address fracture risk in traumatic amputees. [ABSTRACT FROM AUTHOR]

Findings on the association between abdominal obesity and hip fracture were summarized in a meta-analysis in 2017; however, no study has examined the dose-response association between abdominal fat indices and hip fracture. Also, we found no meta-analysis investigating other types of bone fractures including any vertebral fractures in relation to abdominal obesity. Therefore, the present systematic review and dose-response meta-analysis of prospective cohort studies were conducted to examine the association between abdominal obesity and different types of bone fractures. A comprehensive literature search was done by searching PubMed, Scopus, Web of Science, and Google Scholar until October 2021. In total, 23 articles from prospective cohort studies with a total sample size of 3,456,631 participants were included. During the follow-up periods ranging between 4 and 26 years, 137,989 cases of bone fracture were recorded. After comparing the highest and lowest categories of abdominal fat indices, the summary relative risks (RRs) of any, hip, and vertebral fractures were 0.99 (95% CI: 0.81–1.20), 1.09 (95% CI: 0.82–1.43), and 1.18 (95% CI: 1.05–1.33), respectively, indicating a significant positive association between abdominal obesity and risk of vertebral fracture. In the non-linear dose-response analysis, abdominal obesity based on the waist-to-hip ratio (WHR) was positively associated with an increased risk of hip fracture from 0.7 to 1.1 units of WHR. In the linear analysis, a 10 cm increase in waist circumference (WC) was associated with a 3% higher risk of vertebral fracture. We found no other dose-response association for other types of bone fractures. In conclusion, abdominal obesity may be associated with a higher risk of hip and vertebral fractures.

Background: The risk factors for subsequent fractures following an initial hip fracture are not entirely understood. This study examined the clinical characteristics of hip fracture patients to identify potential risk factors associated with a higher risk of experiencing subsequent fractures. Methods: We conducted a nested case-control study using data from the Chinese PLA General Hospital Hip Fracture Cohort between January 2008 and March 2022. The cases were individuals who experienced subsequent fractures following an initial hip fracture. Each case was matched with up to 2 controls who did not develop subsequent fractures. Important clinical factors were compared across groups, including traditional fracture risk factors and potential risk factors (e.g., comorbidities, falls risk, physical impairment, calcium or vitamin D use, and anti-osteoporosis medications). Conditional logistic regression analyses were used to evaluate the impact of these clinical features as potential risk factors for subsequent fractures. Results: A total of 96 individuals who suffered from subsequent fractures were matched with 176 controls. The median time between the initial hip fracture and the subsequent fracture was 2.1 years. The overall proportion of patients receiving anti-osteoporosis treatment after initial hip fracture was 25.7%. In the multivariable regression analysis, living in a care facility (OR = 3.78, 95%CI: 1.53–9.34), longer hospital stays (OR = 1.05, 95%CI: 1.00–1.11), and falls after discharge (OR = 7.58, 95%CI: 3.37–17.04) were associated with higher odds of subsequent fractures. Conclusions: This study showed that living in a care facility, longer hospital stays, and falls after discharge may be independent risk factors for repeat fractures following an initial hip fracture. These findings could be used to identify and manage patients at high risk of subsequent fractures. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to explore the impact of sarcopenia on clinical outcomes after percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF). Methods: We retrospectively analyzed the medical records of patients with single-segment OVCF who underwent percutaneous kyphoplasty (PKP) between September 2021 and August 2022. Patients were categorized into a sarcopenia group (43 patients) and a non-sarcopenia group (125 patients) based on their Advanced Skeletal Muscle Index (ASMI). Clinical and radiological data were collected and analyzed. Results: There were no significant differences between the sarcopenia and non-sarcopenia groups in age, sex, bone mineral density (BMD), body mass index (BMI), fractured segment, fracture type, surgical approach, bone cement volume, bone cement distribution, comorbidities, preoperative and immediate postoperative VAS and ODI scores (P >.05). However, the time to ambulation, hospital stays, VAS and ODI scores at follow-up, excellent/good rate, and the incidence of residual pain and re-fractures in the non-sarcopenia group were significantly better than those in the sarcopenia group (P <.05). Meanwhile, radiological outcomes, including regional kyphosis and vertebral height loss rate, were significantly better in the non-sarcopenia group than in the sarcopenia group at 6 and 12 month follow-ups (P <.05). Conclusion: Clinical outcomes after PKP in patients with OVCF could be negatively affected by sarcopenia. Therefore, prevention and treatment of sarcopenia should be actively considered in the management of patients with OVCF. [ABSTRACT FROM AUTHOR]

Objective: Calcium pyrophosphate deposition (CPPD) disease was associated with osteopenia in two cross‐sectional studies. We compared fracture risks in patients with acute calcium pyrophosphate (CPP) crystal arthritis versus matched comparators. Methods: We performed a longitudinal cohort study using electronic health record data from a single large academic health system, with data from 1991 to 2023. Patients with one or more episodes of acute CPP crystal arthritis were matched to comparators on the index date (first documentation of "pseudogout" or synovial fluid CPP crystals or matched encounter) and first encounter in the health system. The primary outcome was first fracture at the humerus, wrist, hip, or pelvis. We excluded patients with fracture before the index date. Covariates included demographics, body mass index, smoking, comorbidities, health care use, glucocorticoids, and osteoporosis treatments. We estimated incidence rates and adjusted hazard ratios for fracture. Sensitivity analyses excluded patients prescribed glucocorticoids, patients prescribed osteoporosis treatments, or patients with rheumatoid arthritis and additionally adjusted for chronic kidney disease. Results: We identified 1,148 patients with acute CPP crystal arthritis matched to 3,730 comparators, with a mean age of 73 years. Glucocorticoids and osteoporosis treatments were more frequent in the acute CPP crystal arthritis cohort. Fracture incidence rates were twice as high in the acute CPP crystal arthritis cohort (11.7 per 1,000 person‐years) versus comparators (5.5 per 1,000 person‐years). After multivariable adjustment, fracture relative risk was twice as high in the acute CPP crystal arthritis cohort (hazard ratio 1.8 [95% confidence interval 1.3–2.3]); results were similar in sensitivity analyses. Conclusion: In this first published study of fractures and CPPD, fracture risk was nearly doubled in patients with acute CPP crystal arthritis. [ABSTRACT FROM AUTHOR]
