PURPOSE: The current standard method for pectus excavatum (PE) repair is the Nuss procedure. One major postoperative complication is the displacement of the implanted metal bar, which is used to remodel the chest wall. Blocking the possible ways that the bar can be displaced with the use of stabilizers and peri/intracostal sutures has reduced the incidence of bar displacement. Despite the modifications, bar dislocation is often reported. We adopted the medial position stabilizer placement method and imposed no postoperative restrictions. In this study, we analyzed the bar dislocation rate with this modification and concurrent postoperative full activity. METHODS: Nuss procedure modification where stabilizers are placed bilaterally in the medial location was done on patients irrespective of age and Haller index greater than 3.25. A single bar was used for all patients. Cryoanalgesia was performed on every patient. No postoperative restrictions were imposed on the patients. Full immediate activities, including sports, were allowed. RESULTS: 114 patients (103 male, 11 female) were analyzed from 2016 to 2023. The median age was 15 years old. There was zero incidence of bar displacement. The combined incidence of other postoperative complications was 4%: 2 wound infections and 2 hematoma formations, both needing incision and drainage. CONCLUSION: Bilateral medial stabilizer placement resulted in no incidence of bar dislocation. Return to immediate full activities after the Nuss procedure did not appear to increase the incidence of bar displacement if stabilizers were placed medially.

BACKGROUND: Increasing use of hype language (eg, language overstating research impact) has been documented in the scientific community. Evaluating language in abstracts is important because readers may use abstracts to extrapolate findings to entire publications. Our purpose was to assess the frequency of hype language within orthopaedic surgery. METHODS: One hundred thirty-nine hype adjectives were previously identified using a linguistics approach. All publicly available abstracts from 18 orthopaedic surgery journals between 1985 and 2020 were obtained, and hype adjectives were tabulated. Change in frequency of these adjectives was calculated. RESULTS: A total of 112,916 abstracts were identified. 67.0% (948/1414) of abstracts in 1985 contained hype adjectives, compared with 92.5% (5287/5714) in 2020. The average number of hype adjectives per abstract increased by 136% (1.1 to 2.6). Of the 139 adjectives, 87 (62.5%) increased in frequency and 40 (28.7%) decreased in frequency while 12 (9%) were not used. The hype adjectives with the largest absolute increases in frequency were quality (+324wpm), significant (+320wpm), systematic (+246wpm), top (+239wpm), and international (+201wpm). The five hype adjectives with the largest relative increases in frequency were novel (+10500%), international (+2850%), urgent (+2600%), robust (+2300%), and emerging (+1400%). CONCLUSION: Promotional language is increasing in orthopaedic surgery abstracts. Authors, editors, and reviewers should seek to minimize the usage of nonobjective language.

Introduction: orthopedic deviceassociated infections (ODI) are considered surgical site infections (SSI). SSIs are generally attributed to contamination during surgery, but they require certain factors for their development. Therefore, the objective of this study was to analyze the risk factors for the development of SSIs in patients with closed fractures. Material and methods: a retrospective observational study was carried out, where records of patients with closed bone fractures undergoing surgery were reviewed during the period from January to December 2020. The variables studied were age, sex, BMI, comorbidities, as well as surgery time, ischemia time, intraoperative bleeding, type of fracture, serum glucose 24-48 hours prior to surgery and blood transfusion. The analysis was performed with Fisher, OR and binary logistic regression. Accepted statistical value: p < 0.05. Results: sample of 131 patients. Mean age was 47.6 ± 18.7 years. Diabetes mellitus (DM) 24.4%, systemic arterial hypertension (SAH) 23.7%, obesity 70.2%, smoking 47.3% and alcoholism 67.9%. Simple fractures 34.4% and complex 65.6%. 19.1% presented infection after surgery. Risk factors found: glucose > 120 mg/dl OR: 4.9 (95% CI, 1.6-15.7, p = 0.001), surgery time > 120 minutes OR: 6.7 (95% CI, 2.3-20.1, p = 0.001), male sex OR: 4.5 (95% CI, 1.5-13.9, p = 0.009) and age < 50 years OR: 0.3 (95% CI, 0.07-0.8, p = 0.031). Conclusions: having a glucose > 120 mg/dl before surgery and a surgical time > 120 minutes as risk factors for the development of ODI in closed long. g bone fractures. [ABSTRACT FROM AUTHOR]

Objectives: To determine whether adherence to hip fracture clinical care quality indicators influences mortality among people who undergo surgery after hip fracture in New South Wales, both overall and by individual indicator. Study design: Retrospective population‐based study; analysis of linked Australian and New Zealand Hip Fracture Registry (ANZHFR), hospital admissions, residential aged care, and deaths data. Setting, participants: People aged 50 years or older with hip fractures who underwent surgery in 21 New South Wales hospitals participating in the ANZHFR, 1 January 2015 – 31 December 2018. Main outcome measures: Thirty‐day (primary outcome), 120‐day, and 365‐day mortality (secondary outcomes) by clinical care indicator adherence level (low: none to three of six indicators achieved; moderate: four indicators achieved; high: five or six indicators achieved) and by individual indicator. Results: Registry data were available for 9236 hip fractures in 9058 people aged 50 years or older during 2015–2018; the mean age of patients was 82.8 years (standard deviation, 9.3 years), 5510 patients were women (69.4%). Complete data regarding adherence to clinical care indicators were available for 7951 fractures (86.1%); adherence to these indicators was high for 5135 (64.6%), moderate for 2249 (28.3%), and low for 567 fractures (7.1%). After adjustment for age, sex, comorbidity, admission year, pre‐admission walking ability, and residential status, 30‐day mortality risk was lower for high (adjusted relative risk [aRR], 0.40; 95% confidence interval [CI], 0.30–0.52) and moderate indicator adherence hip fractures (aRR, 0.61; 95% CI, 0.46–0.82) than for low indicator adherence hip fractures, as was 365‐day mortality (high adherence: aRR, 0.59 [95% CI, 0.51–0.68]; moderate adherence: aRR, 0.74 [95% CI, 0.63–0.86]). Orthogeriatric care (365 days: aRR, 0.78; 95% CI, 0.61–0.98) and offering mobilisation by the day after surgery (365 days: aRR, 0.74; 95% CI, 0.67–0.83) were associated with lower mortality risk at each time point. Conclusions: Clinical care for two‐thirds of hip fractures attained a high level of adherence to the six quality care indicators, and short and longer term mortality was lower among people who received such care than among those who received low adherence care.

Background/Objectives: Informed consent for anesthesia poses both legal challenges and problems of understandable communication. Fulfilling all the requirements through anesthesiologists directly interacting with patients is a time- and staff-consuming strategy. Given today's smart technologies, notably including virtual reality (VR), we explored in a prospective randomized study whether 'VR-assisted informed consent' could improve this situation. Methods: Fifty patients scheduled for orthopedic surgery were randomized. In the control group, informed consent was obtained via patient–specialist dialogs only. The patients in the study group, wearing a head-mounted display, watched an 8 min immersive 3D movie with the standard explanations of general anesthesia, followed by a patient–specialist dialog to address open questions. The time spent on the dialogs in both groups was evaluated as the primary outcome variable. As secondary variables, we analyzed both a three-item Likert scale on patient satisfaction with the VR experience and cost differences between both groups. Results: Patient–specialist dialogs were carried on for median (IQR) durations of 93 (20–182) seconds in the study group versus 665 (261–829) seconds in the control group (p < 0.001). All the patients exposed to VR rated this experience as favorable (87.5%) or neutral (12.5%). Based on anesthesiologists' incomes in the US and UK, our approach would reduce the staff expenditure for each patient–specialist dialog by median amounts of USD ≈40 or ≈11, respectively (2 × p < 0.001). Conclusions: 'VR-assisted informed consent' for anesthesia is well accepted by patients and reduces the time requirements for patient–specialist dialogs, thus pointing out a potential avenue towards increasing the work-time efficiency of anesthesiologists.

Purpose: Osteosynthesis of a clavicular fracture can obtain good clinical results even with conservative treatment. The development of surgical techniques and improvements in internal fixation have led to the use of metal plates and screws. Although there are intramedullary nails or minimally invasive plate osteosynthesis that can reduce soft tissue damage, these techniques are not used often because most require a skin incision about the length of the metal plate to be inserted. This study compared the postoperative pain to determine the appropriate injection depth. Materials and Methods: A prospective, single-institute, single-blind, randomized study was designed. The patients in the study had clavicular fractures and who underwent the removal of implant. The patients judged to have difficulty indicating pain were excluded. Ropivacaine was injected between plate fixation and muscle suturing. The visual analog scale (VAS) pain score, patient-controlled analgesia (PCA) use, and additional pain medication usage were measured after surgery and every 4 hours. Results: Thirty-four clavicle shaft fracture patients were classified into 16 patients in the subcutaneous injection group and 18 in the muscle injection group. Seventeen implant removal patients were divided into eight patients in the subcutaneous injection group and another nine in the muscle injection group. In the fracture group, the mean VAS for the subcutaneous injection group was 4.20±2.68 immediately after surgery, 4.47±1.85 at 4 hours, 1.93±1.44 at 24 hours, and 1.60±1.35 at 48 hours. The mean VAS for the muscle injection group was 4.23±1.59 immediately after surgery, 3.00±1.47 at 4 hours, 1.69±1.03 at 24 hours, and 1.31±1.11 at 48 hours; the mean VAS score was not statistically significant in the two groups (p=0.332). In the implant removal group, the mean VAS for the subcutaneous injection group was 4.75±1.58 immediately after surgery, 3.75±1.04 at 4 hours, 1.75±0.89 at 24 hours, and 1.75±0.89 at 48 hours. The mean VAS for the muscle injection group was 3.78±1.20 immediately after surgery, 3.22±0.83 at 4 hours, 1.89±1.17 at 24 hours, and 1.11±1.01 at 48 hours; the mean VAS score was not statistically significant in the two groups (p=0.181). Conclusion: The postoperative VAS pain score and PCA usage were not statistically significant regardless of the ropivacaine injection site in clavicular surgery, but each group had significantly different VAS pain scores and PCA usage according to time after surgery. In addition, the muscle injection group tended to have a lower average VAS than the subcutaneous injection group in the implant removal patient group. [ABSTRACT FROM AUTHOR]

Background: Despite significant advances in patient treatment, infection remains a complication after surgery. The present study compared the incidence and severity of wound infection with two methods of washing the primary prep area with 70% alcohol and normal saline in patients who are candidates for orthopedic surgery in Kowsar Hospital of Sanandaj, Iran. Methods: This single-blinded randomized clinical trial was conducted on 190 candidates for upper limb orthopedic surgery aged 18 to 65. Patients were randomly assigned to two alcohol and normal saline groups based on the table of random numbers. The primary outcome of this clinical trial was the incidence and severity of wound infection after surgery, which was measured by the standard scale of the Asepsis index. The results were analyzed using SPSS version 23, and statistical values less than 0.05 were considered significant. Results: Patients’ hospitalization duration in the intervention group was (3.02±1.04 days) and in the control group (2.86±1.03 days) showed no significant statistical difference (p=0.297). The frequency of wound infection in the alcohol group was lower than in the normal saline group. this difference was statistically significant (p=0.023). Also, the severity of wound infection in the 70% alcohol group (Mean=5.12, SD=3.19) was lower than in the normal saline group (Mean=7.69, SD=4.12). This difference was statistically significant (p<0.001). Conclusion: The present clinical trial showed that the incidence and severity of wound infection after surgery were lower in the group washing the skin of the surgical area with alcohol compared to the group washing with normal saline.

Objective: This meta-analysis aimed to explore the impact of prophylactic negative pressure wound therapy (NPWT) on the occurrence of deep surgical site infections (SSIs) following orthopedic surgery. Methods: A systematic search was conducted across Medline, Embase, Cochrane Library, and Web of Science databases for articles concerning NPWT in patients who underwent orthopedic surgery up to May 20, 2024. Using Stata 15.0, the combined odds ratios (ORs) were calculated with either a random-effects model or a fixed-effects model, depending on the heterogeneity values. Results: From a total of 440 publications, studies that utilized NPWT as the experimental group and conventional dressings as the control group were selected to analyze their impact on SSIs. Ultimately, 32 studies met the inclusion criteria. These included 12 randomized controlled trials and 20 cohort studies, involving 7454 patients, with 3533 of whom received NPWT and 3921 of whom were treated with conventional dressings. The results of the meta-analysis demonstrated that the NPWT group had a lower incidence of deep SSIs in orthopedic surgeries than did the control group [OR 0.64, 95% CI (0.52, 0.80), P = 0.0001]. Subgroup analysis indicated a notable difference for trauma surgeries [OR 0.65, 95% CI (0.50, 0.83), P = 0.001], whereas joint surgeries [OR 0.65, 95% CI (0.38, 1.12), P = 0.122] and spine surgeries [OR 0.61, 95% CI (0.27, 1.35), P = 0.221] did not show significant differences. Additionally, when examined separately according to heterogeneity, trauma surgeries exhibited a significant difference [OR 0.50, 95% CI (0.31, 0.80), P = 0.004]. Conclusion: The results of our study indicate that the prophylactic use of NPWT reduces the incidence of deep SSIs following orthopedic trauma surgery when compared to the use of conventional dressings. We postulate that the prophylactic application of NPWT in patients at high risk of developing complications from bone trauma may result in improved clinical outcomes and an enhanced patient prognosis.

Purpose: Lower extremity chronic exertional compartment syndrome (LE-CECS) can limit rigorous physical activity, particularly in the US military, and fasciotomy is a potential treatment. Associations between LE-CECS, fasciotomy, and occupational outcomes appear understudied. We studied active-duty US service members to identify whether LE-CECS diagnoses and fasciotomy for LE-CECS predict military service separation. Methods: We conducted a retrospective cohort study of 1,103,417 individuals who entered service during 2011 to 2017. Distributions of separation statuses and independent variables were tabulated, and sex-specific multivariable regression models were computed for separation outcomes. Results: LECECS was associated with a 474% medical service separation risk in men (95% confidence interval (CI) for adjusted risk ratio: 5.21 to 6.33) and a 282% increase in women (CI: 2.99 to 4.88). Among 1947 patients with LE-CECS, men saw a 57% nonmedical separation risk increase (CI: 1.27 to 1.93) and women had a 119% increase (CI: 1.10 to 4.35) when anterior and/or lateral compartment procedures occurred. Men with LE-CECS and any posterior procedures saw a 47%nonmedical separation risk increase (CI: 1.17 to 1.86). Men with anterior and/or lateral procedures and any posterior procedures experienced 36% (CI: 1.09 to 1.71) and 78% (CI: 1.40 to 2.26) medical separation risk increases, respectively. No statistically significant risk increases for the outcomes were otherwise seen for women. Conclusions: LE-CECS was associated with increased military service discharge risks. Among the affected patients, positive effects on career longevity were not seen in association with fasciotomy. However, fasciotomy could simply serve as a marker of the most refractory cases that are least likely to continue service. More study is needed to clarify causal pathways and identify patients who may derive career benefits from surgical treatment. [ABSTRACT FROM AUTHOR]

Taurolidine, known for its broad-spectrum antimicrobial properties and low toxicity, has shown promise in reducing infections in various surgical settings. However, it has not been extensively evaluated in orthopedic surgery. This study assessed the efficacy of taurolidine irrigation in reducing surgical site infections in patients undergoing ankle fracture surgery. A retrospective review was conducted for patients >20 years old who underwent ankle fracture surgery between March 2016 and March 2023, with follow-ups exceeding 6 months. Patients were classified into the following two groups: those who underwent normal saline (NS) irrigation and those who underwent taurolidine irrigation. Minor infections were defined as requiring additional oral antibiotics postoperatively, while major infections were characterized by hospitalization or reoperation due to infection within 3 months. Of 844 patients, 688 were included. The taurolidine group (n = 328) had a significant reduction in minor infections (7.3% vs. 22.5%, odds ratio = 0.410, p = 0.028) compared to the NS group (n = 360). Major infections were fewer in the NS group (1.2% vs. 0%, p = 0.051), but the number of cases was too small for reliable analysis. Taurolidine irrigation significantly reduces the occurrence of minor infections in ankle fracture surgeries when compared to normal saline irrigation. [ABSTRACT FROM AUTHOR]

Objectives: To examine patient, surgical and hospital factors associated with Day‐1 postoperative mobility after hip fracture surgery in older adults. Methods: A cohort study using Australia and New Zealand Hip Fracture Registry was conducted. Participants were aged older than 50 years and underwent hip fracture surgery between 1 January 2020 and 31 December 2020 inclusive. The outcome was standing and step transferring out of bed onto a chair and/or walking Day‐1 after hip fracture surgery. Results: Mean age was 82 years and 68% were women. Of 12,318 patients with hip fracture, 5981 (49%) actually mobilised Day‐1. Odds of actual first‐day mobilisation were lower for individuals usually walking with either stick or crutch (OR = 0.71, 95% CI 0.62–0.82) or two aids or frame (OR = 0.57, 95% CI 0.52–0.64) or wheelchair/bed bound (OR = 0.24, 95% CI 0.17–0.33); who had impaired cognition preadmission (OR = 0.57, 95% CI 0.51–0.64); from aged care facilities (OR = 0.59, 95% CI 0.52–0.67); had an American Society of Anaesthesiologists grade 2 (OR = 0.63, 95% CI 0.41–0.97), 3 (OR = 0.31, 95% CI 0.20–0.47) or 4 or 5 (OR = 0.21, 95% CI 0.14–0.32); surgery delay >48 h (OR = 0.81, 95% CI 0.71–0.91); and restricted/non‐weight‐bearing status immediately postoperatively (OR = 0.53, 95% CI 0.42–0.67). Conclusions: Both non‐modifiable and modifiable patient and surgical factors influence first‐day mobilisation after hip fracture surgery. Reducing time to surgery might assist future quality improvement efforts to increase Day‐1 postoperative mobility. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to explore the effect of five-element music therapy on sleep status during perioperative period and psychological regulation in patients undergoing orthopedic surgery. Methods: The medical records of patients who underwent orthopedic surgery from March 2021 to December 2023 in the Gansu Provincial Hospital of Traditional Chinese Medicine were retrospectively analyzed. Patients were divided into two groups in accordance with the nursing time period. The control group (88 patients) received routine nursing, and the observation group (78 patients) received five-element music management in the perioperative period based on routine nursing. The management time was from admission to one week after surgery, with 30 min/times, TID. The sleep, physical signs, pain condition, and anxiety status of the two groups were compared on admission, before surgery, and one week after surgery. Results: On admission, no significant difference in the scores of the Pittsburgh Sleep Quality Index (PSQI), the pain rating index (PRI), and the Self-Rating Anxiety Scale (SAS) was found between the two groups (P > 0.05). Before and one week after surgery, the PSQI, PRI, and SAS scores of the observation group were significantly lower than those of the control group (P < 0.001). No significant difference was found in systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) between the two groups on admission and one week after surgery (P > 0.05). Before surgery, the observation group had significantly lower indices of SBP, DBP, and HR than the control group (P < 0.05). Conclusion: Five-element music stimulation in the perioperative period can improve the pain and anxiety of patients undergoing orthopedic surgery and enhance their sleep status.

Subgroup analysis indicated a notable difference for trauma surgeries [OR 0.65, 95% CI (0.50, 0.83), P = 0.001], whereas joint surgeries [OR 0.65, 95% CI (0.38, 1.12), P = 0.122] and spine surgeries [OR 0.61, 95% CI (0.27, 1.35), P = 0.221] did not show significant differences. Additionally, when examined separately according to heterogeneity, trauma surgeries exhibited a significant difference [OR 0.50, 95% CI (0.31, 0.80), P = 0.004]. Conclusion The results of our study indicate that the prophylactic use of NPWT reduces the incidence of deep SSIs following orthopedic trauma surgery when compared to the use of conventional dressings. We postulate that the prophylactic application of NPWT in patients at high risk of developing complications from bone trauma may result in improved clinical outcomes and an enhanced patient prognosis.

Tranexamic acid (TXA) is a synthetic antifibrinolytic agent that has been used for several decades to reduce blood loss during surgery and after trauma. TXA was traditionally used to reduce bleeding in various clinical settings such as menorrhagia, hemophilia, or other bleeding disorder. Numerous studies have demonstrated the efficacy of TXA in reducing blood loss and the need for transfusions. Interest in the potential applications of TXA beyond its traditional use has been growing recently, with studies investigating the use of TXA in postpartum hemorrhage, cardiac surgery, trauma, neurosurgery, and orthopedic surgery. Despite its widespread use and expanding indications, data regarding the safe and appropriate use of TXA is lacking. Recent clinical trials have found various potential risks and limitations in the long-term benefits of TXA. This narrative review summarizes the clinical applications and limitations of TXA.

Abstract Background With the increased use of patient-reported outcomes measures (PROMs) to assess spine surgery outcomes, it is important to understand how patients interpret their health changes over time. The measurement of cognitive-appraisal processes enables the quantification of how individuals think about quality of life (QOL). This study examined how appraisal processes were associated with patients’ views of their role in managing their health—patient activation. Methods This longitudinal cohort study from August 2019 to January 2022 included 222 adults undergoing spine surgery for cervical (n = 107) and/or lumbar (n = 148) pathology at an academic medical center. PROMs assessed disability (Neck Disability Index for cervical or Oswestry Disability Index for lumbar) and mental health (PROMIS-29 v2.0), cognitive-appraisal processes (QOLAPv2-SF), and patient activation (Patient Activation Measure). ANOVA models were used to examine the relationships between QOL and cognitive appraisal processes before and after surgery, overall and stratified by patient-activation stage. Effect sizes facilitated interpretation. Results There were significant improvements in pain-related disability and mental health following surgery. Cognitive appraisal processes explained substantial amounts of variance, particularly with changes in mental health (45% before surgery, 75% at three months, and 63%, at 12-months after surgery). With respect to physical disability, less disability was associated with a lesser focus on negative aspects of QOL. Appraisal explained the most variance before surgery for high-activation patients. At 12-months post-surgery, however, appraisal explained the most variance for the low-activation patients. Appraisal explained similar amounts of variance in mental health at baseline and three-months post-surgery for all activation groups, but substantially more variance in the low-activation group at 12-months post-surgery. There were differences in the direction of appraisal-outcome associations by activation group in selected appraisal items/domains. Conclusions Cognitive-appraisal processes demonstrate a significant relationship with QOL among spine surgery patients. These processes explain substantial variance in pain-related disability and mental health, especially among those high in activation before surgery and those low in activation at 12-months post-surgery. Our findings suggest that patients’ ways of thinking about their health may be effective targets of motivational coaching, to help them become more engaged over the recovery trajectory.

Abstract Background The aim of this case report is to evaluate minimally invasive stabilization using screws and cement for acetabular metastatic tumor and summarize the indications and contraindications for minimally invasive stabilization of acetabular metastatic tumors with screw and cement techniques. Case presentation Under imaging guidance, a patient with acetabular metastatic tumor was treated with hollow screw combined with bone cement fixation. Ischial screw, ascending branch screw, and anterior and posterior screws were inserted to firmly fix the anterior and posterior column of the acetabulum. At the same time, the third screw connected the anterior and posterior columns together, combined with bone cement into the fracture site to further increase local stability and resist bone defects caused by local tumor osteolysis. The patient was a 52-year-old Uygur male. Herein, we summarize his clinical symptoms and operation. Differences in visual analog scale and walking function (Musculoskeletal Tumor Society) before operation and at 2 months, 6 months, and 12 months after operation were compared. Results Postoperative complications and tumor progression were recorded. The patient was followed up for 16 months, and the operative time was 60 minutes. In total, 20 ml of bone cement was injected into the acetabular posterior column and the top of the acetabulum. VIsual analog scale score was 8 before operation, 3 at 2 months, 3 at 6 months, and 2 at 12 months after operation. Musculoskeletal Tumor Society function was 13 before operation, 23 at 2 months, 25 at 6 months, and 26 at 12 months after operation. During follow-up, no cement leakage, fever, hip nerve injury, pulmonary embolism, or imaging findings of further destruction of the acetabulum and surrounding bone were noted. Conclusion This case report shows that the treatment of acetabular metastatic cancer with minimally invasive stabilization using screws and cement under the C arm can effectively relieve pain and enhance the strength of the pelvis, and is innovative and feasible.

Background The intraoperative use of tourniquets is associated with several complications, including hyperthermia. We present the first documented case of tourniquet-induced hyperthermia in a pediatric patient at our institution. Case A 5-year-old female with no past medical history underwent tendon release surgery for congenital talipes equinovarus under general anesthesia. Following inflation of a pneumatic tourniquet to a pressure of 250 mmHg on her left thigh, the patient experienced a gradual increase in body temperature. Despite the implementation of cooling measures, the temperature continued to increase until it plateaued. The hyperthermia gradually resolved upon deflation of the tourniquet. Conclusions Tourniquet-induced hyperthermia should be considered as a potential cause of intraoperative hyperthermia, particularly in the absence of typical signs of malignant hyperthermia. Early recognition and appropriate management, including deflation of the tourniquet and implementation of cooling measures, are crucial for preventing potential complications associated with hyperthermia.

Background: The incidence of anterior cruciate ligament (ACL) injuries in children is on the rise. Despite this trend, the optimal management of these injuries remains a matter of ongoing debate. In this light, our study seeks to assess the clinical, radiological, and functional outcomes of transphyseal ACL reconstruction in preadolescent patients in the medium-term. Methods: This prospective study included preadolescent patients aged up to 12 years who underwent ACL transphyseal reconstruction between 2010 and 2020 and had a minimum follow-up of 2 years. Clinical assessments encompassed joint stability and range of motion. Furthermore, leg length discrepancy (LLD) and femorotibial alignment were evaluated both clinically and radiologically using full-length lower limb standing radiographs. Pre- and postoperative functional outcomes were assessed using the International Knee Documentation Committee (IKDC) and Lysholm scales, and the return to normal sports activity was evaluated using the ACL-Return to Sport after Injury (ACL-RSI) scale. Complications and relevant follow-up data were also recorded. Statistical analyses were conducted to evaluate these outcomes. Results: A total of 35 preadolescent patients, consisting of 24 males and 11 females, with a mean age at surgery of 11.2 ± 0.7 years (8.7–12), were included in the study. The mean follow-up was 52.3 ± 20.7 months (24.1–95.9). No significant growth disturbances or clinically relevant LLD were evidenced. All patients demonstrated clinically stable knees with full range of motion at the 2-year follow-up. There were statistically significant improvements in pre- and postoperative IKDC (39.3 ± 13.5 vs. 99.7 ± 0.8, p < 0.005) and Lysholm scores (48.2 ± 15.1 vs. 99.6 ± 1.4, p < 0.005). All but two patients were able to return to their pre-injury level of sports activity, with a mean ACL-RSI score of 93.5 ± 1.3. The analysis revealed an 8.6% rerupture rate and an 11.4% rate of contralateral ACL injuries, with 5-year survival rates of 92.3% and 88.8%, respectively. Subgroup analyses based on age, gender, surgical delay, or associated meniscal lesions did not reveal any significant differences in functional outcomes. Additionally, there was no discernible relationship between age or timing of ACL reconstruction and the risk of meniscal injuries. Conclusions: Our study reinforces the value of ACL reconstruction in skeletally immature preadolescent patients, with transphyseal technique proven to be a safe, effective, and technically simpler option, even for children under the age of 12. The findings indicate excellent functional outcomes, a high rate of successful return to sporting activities, and minimal to no incidence of growth-related complications in the medium-term. Level of evidence: Level II, prospective comparative cohort study, before and after intervention. [ABSTRACT FROM AUTHOR]

Background/Aim. The number of pelvic traumas is increasing globally, mostly due to car accidents but also due to an increasing number of sports and recreational traumas. Tile C-type unstable pelvic trauma (TCUPT) is a kind of high-energy trauma that occurs during traffic accidents or accidents when falling from big heights. The aim of our study was to explore the application of the internal fixation (INFIX) system for the anterior pelvic ring (APR) with simultaneous application of sacroiliac screw (SS) INFIX of the posterior pelvic ring (PPR) in TCUPT. Methods. The subjects (89 of them in total) were recruited among patients with TCUPT from December 2020 to December 2023. A retrospective analysis of the subjects' data was performed, after which the subjects were divided into two groups based on different therapeutic regimens applied: group A (INFIX system for the APR + SS INFIX of the PPR, n = 46) and group B (external fixator for the APR + SS INFIX of the PPR, n = 43). Results. In comparison with group B, group A had a shorter period before the commencement of the first activity after surgery, shorter fracture healing time and joint function recovery time, as well as length of hospital stay (t = 6.623, 4.796, 7.992, and 5.227, respectively, p < 0.05). The surgery duration and bleeding volume showed no significant differences between the two groups (t = 1.433, 1.123, respectively, p > 0.05). The fracture reduction outcomes were better in group A than in group B (Z = 2.058, p < 0.05). The incidence rate of complications was lower in group A than in group B (2.17% vs. 18.60%) (2 = 4.917, p < 0.05). Conclusion. For patients with TCUPT, the INFIX system for the APR with simultaneous application of SS INFIX of the PPR achieves good fracture reduction outcomes. [ABSTRACT FROM AUTHOR]

Background: With the increased use of patient-reported outcomes measures (PROMs) to assess spine surgery outcomes, it is important to understand how patients interpret their health changes over time. The measurement of cognitive-appraisal processes enables the quantification of how individuals think about quality of life (QOL). This study examined how appraisal processes were associated with patients' views of their role in managing their health—patient activation. Methods: This longitudinal cohort study from August 2019 to January 2022 included 222 adults undergoing spine surgery for cervical (n = 107) and/or lumbar (n = 148) pathology at an academic medical center. PROMs assessed disability (Neck Disability Index for cervical or Oswestry Disability Index for lumbar) and mental health (PROMIS-29 v2.0), cognitive-appraisal processes (QOLAPv2-SF), and patient activation (Patient Activation Measure). ANOVA models were used to examine the relationships between QOL and cognitive appraisal processes before and after surgery, overall and stratified by patient-activation stage. Effect sizes facilitated interpretation. Results: There were significant improvements in pain-related disability and mental health following surgery. Cognitive appraisal processes explained substantial amounts of variance, particularly with changes in mental health (45% before surgery, 75% at three months, and 63%, at 12-months after surgery). With respect to physical disability, less disability was associated with a lesser focus on negative aspects of QOL. Appraisal explained the most variance before surgery for high-activation patients. At 12-months post-surgery, however, appraisal explained the most variance for the low-activation patients. Appraisal explained similar amounts of variance in mental health at baseline and three-months post-surgery for all activation groups, but substantially more variance in the low-activation group at 12-months post-surgery. There were differences in the direction of appraisal-outcome associations by activation group in selected appraisal items/domains. Conclusions: Cognitive-appraisal processes demonstrate a significant relationship with QOL among spine surgery patients. These processes explain substantial variance in pain-related disability and mental health, especially among those high in activation before surgery and those low in activation at 12-months post-surgery. Our findings suggest that patients' ways of thinking about their health may be effective targets of motivational coaching, to help them become more engaged over the recovery trajectory.

Objective: This study aimed to explore the effect of five-element music therapy on sleep status during perioperative period and psychological regulation in patients undergoing orthopedic surgery. Methods: The medical records of patients who underwent orthopedic surgery from March 2021 to December 2023 in the Gansu Provincial Hospital of Traditional Chinese Medicine were retrospectively analyzed. Patients were divided into two groups in accordance with the nursing time period. The control group (88 patients) received routine nursing, and the observation group (78 patients) received five-element music management in the perioperative period based on routine nursing. The management time was from admission to one week after surgery, with 30 min/times, TID. The sleep, physical signs, pain condition, and anxiety status of the two groups were compared on admission, before surgery, and one week after surgery. Results: On admission, no significant difference in the scores of the Pittsburgh Sleep Quality Index (PSQI), the pain rating index (PRI), and the Self-Rating Anxiety Scale (SAS) was found between the two groups (P > 0.05). Before and one week after surgery, the PSQI, PRI, and SAS scores of the observation group were significantly lower than those of the control group (P < 0.001). No significant difference was found in systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) between the two groups on admission and one week after surgery (P > 0.05). Before surgery, the observation group had significantly lower indices of SBP, DBP, and HR than the control group (P < 0.05). Conclusion: Five-element music stimulation in the perioperative period can improve the pain and anxiety of patients undergoing orthopedic surgery and enhance their sleep status.

Background: The aim of this case report is to evaluate minimally invasive stabilization using screws and cement for acetabular metastatic tumor and summarize the indications and contraindications for minimally invasive stabilization of acetabular metastatic tumors with screw and cement techniques. Case presentation: Under imaging guidance, a patient with acetabular metastatic tumor was treated with hollow screw combined with bone cement fixation. Ischial screw, ascending branch screw, and anterior and posterior screws were inserted to firmly fix the anterior and posterior column of the acetabulum. At the same time, the third screw connected the anterior and posterior columns together, combined with bone cement into the fracture site to further increase local stability and resist bone defects caused by local tumor osteolysis. The patient was a 52-year-old Uygur male. Herein, we summarize his clinical symptoms and operation. Differences in visual analog scale and walking function (Musculoskeletal Tumor Society) before operation and at 2 months, 6 months, and 12 months after operation were compared. Results: Postoperative complications and tumor progression were recorded. The patient was followed up for 16 months, and the operative time was 60 minutes. In total, 20 ml of bone cement was injected into the acetabular posterior column and the top of the acetabulum. VIsual analog scale score was 8 before operation, 3 at 2 months, 3 at 6 months, and 2 at 12 months after operation. Musculoskeletal Tumor Society function was 13 before operation, 23 at 2 months, 25 at 6 months, and 26 at 12 months after operation. During follow-up, no cement leakage, fever, hip nerve injury, pulmonary embolism, or imaging findings of further destruction of the acetabulum and surrounding bone were noted. Conclusion: This case report shows that the treatment of acetabular metastatic cancer with minimally invasive stabilization using screws and cement under the C arm can effectively relieve pain and enhance the strength of the pelvis, and is innovative and feasible.

Background: The intraoperative use of tourniquets is associated with several complications, including hyperthermia. We present the first documented case of tourniquet-induced hyperthermia in a pediatric patient at our institution. Case: A 5-year-old female with no past medical history underwent tendon release surgery for congenital talipes equinovarus under general anesthesia. Following inflation of a pneumatic tourniquet to a pressure of 250 mmHg on her left thigh, the patient experienced a gradual increase in body temperature. Despite the implementation of cooling measures, the temperature continued to increase until it plateaued. The hyperthermia gradually resolved upon deflation of the tourniquet. Conclusions: Tourniquet-induced hyperthermia should be considered as a potential cause of intraoperative hyperthermia, particularly in the absence of typical signs of malignant hyperthermia. Early recognition and appropriate management, including deflation of the tourniquet and implementation of cooling measures, are crucial for preventing potential complications associated with hyperthermia.

Background: Orthopedic procedures are one of the most common medical procedures in the emergency department (ED) and are also among the most painful procedures performed on the conscious patient. This study aimed to compare different doses of ketofol in procedural sedation and analgesia (PSA) in patients referred to the EDs. Methods: In this double-blinded clinical trial, 296 patients aged 18 years or over who presented with the need for orthopedic procedures in the three academic EDs in 2020 were studied. After completing the written consent, the patients were randomly assigned to four treatment groups. Demographic information, underlying diseases, patients' physical condition, type of orthopedic injuries requiring intervention, and patients' vital signs were recorded in a checklist for each patient. Results: In this study, the mean age, gender, level of education, addiction, patients' physical condition, type of procedures performed, apnea, hypoventilation, bradycardia, hypotension, and agitation in all four treatment groups were not statistically different, but hallucination and hypoxia in group C (propofol 1 mg/kg plus ketamine 0.33 mg/kg) were much less than other groups; thus, oxygen administration was more common in other groups. Conclusion: By testing different doses of ketamine, we concluded that doses of 1 mg and 0.5 mg were associated with more side effects. A dose of 0.33 mg of ketamine has fewer side effects while causing analgesia and sedation as in the above doses. A dose of 0.25 mg of ketamine increases the likelihood of requiring subsequent doses. Therefore, it seems that 0.33 mg of ketamine is the best dose of choice. [ABSTRACT FROM AUTHOR]

ABSTRACT The COVID-19 pandemic has triggered a global crisis in health systems worldwide. Emergency care services have been overloaded, and there have been different changes in the patient’s profile and the most frequent diagnoses. The aim of the study was to compare the number of emergency surgeries in the Hand and Microsurgery group of the quaternary hospital (IOT-FMUSP) from March 2020 to February 2022, the pandemic period, with the previous two years, March 2018 to February 2020. Two hundred and seventy-two patients were evaluated, with a mean age of 39.54 ± 17 years (range 1 to 90 years), 12.50% (n = 34) women and 87.50% (n = 238) men. Between March 2018 and February 2020, 142 (52.21%) emergency upper limb surgeries were performed; between March 2020 and February 2022, 130 surgeries were performed (47.79%). There was a reduction in upper limb surgeries in patients between 26–45 years and blunt injury surgeries. There was also an increase in surgeries in patients over 46, amputations, fractures, re-implantation procedures, and open fracture fixation. Level of evidence III, Retrospective Comparative Study.

ABSTRACT Objectives: Evaluate the prevalence of hospital mortality in older adult patients with femoral fracture undergoing surgical treatment during the COVID-19 pandemic period, and to evaluate whether COVID-19 infection, clinical, and orthopedic factors interfered with mortality. Material and Methods: A retrospective study was conducted by reviewing medical records. Patients over 60 years of age with proximal femoral fracture undergoing surgical treatment were included. Overall mortality was calculated, as well as mortality whose primary or secondary cause was COVID-19 infection, to determine if infection influenced patient mortality. Clinical and orthopedic factors that interfered with mortality were evaluated. Categorical variables were compared using the Chi-square test or Fisher’s exact test. Both unpaired t-test (parametric variables) and Mann-Whitney test (non-parametric variables) were used. The Kaplan-Meier mortality curve was constructed. Conclusion: The mortality of older adult patients with femoral fracture undergoing surgical treatment during the COVID-19 pandemic was 4.2%. Male sex, older age, and those who underwent blood transfusion had higher mortality rates. COVID-infected patients had ten times more chance of death and died twice as fast as the non-infected population. Level of Evidence II, Retrospective Study.

»The rapid increase in the use of electronic medical records (EMRs) has led to some unintended consequences that negatively affect physicians and their patients.»The use of medical scribes may serve as a possible solution to some of the EMR-related concerns.»Research has demonstrated an overall positive impact of having scribes on both physician and patient well-being, safety, and satisfaction.»Adaptation of advances in technology, including remote and asynchronous scribing, use of face-mounted devices, voice recognition software, and applications of artificial intelligence may address some of the barriers to more traditional in-person scribes.

Abstract Background Femoral fractures significantly contribute to disability, predominantly in the elderly. Despite this, data on postoperative pneumonia following femoral fracture surgeries remains sparse. Our study sought to explore the incidence and impact of postoperative pneumonia on outcomes following such surgeries. Methods A retrospective study analyzed femoral fracture patients hospitalized from 2016 to 2022. We scrutinized postoperative outcomes, including pneumonia, hospital stay duration, intensive care unit (ICU) admissions, and in-hospital mortality. We established stringent diagnostic criteria for postoperative pneumonia, incorporating both clinical signs and radiological evidence, excluding patients with prior infections or those discharged within 24 h post-surgery. Statistical analyses involved Chi-square and t-tests, linear regression, and logestic regression using SPSS. Results Out of 636 patients, 10.8% were diagnosed with postoperative pneumonia. The average age was 79.55 ± 8.57 years, with a male prevalence of 47.8%. Common comorbidities were hypertension (78.3%), diabetes (60.9%), and cardiovascular diseases (40.6%). Surgical interventions were categorized as intramedullary nailing (40.6%), partial hip replacement (37.7%), and dynamic hip screw (21.7%). Postoperative pneumonia was associated with older age (AOR = 1.053, 95% CI 1.020 to 1.087, p = 0.002), ICU admission (AOR = 2.283, 95% CI 1.256 to 4.148, p = 0.007), and longer length of hospital stay (AOR = 1.079, 95% CI 1.030 to 1.130, p = 0.001). The presence of pneumonia was associated with a 2.621-day increase in hospitalization after adjusting for other variables (p

BACKGROUND: Nongovernmental organizations (NGOs) from high-income countries provide surgical outreach for patients in low and middle-income countries (LMICs); however, these efforts lack a coordinated measurement of their ability to build capacity. While the World Health Organization and others recommend outreach trips that aim to build the capacity of the local health-care system, no guidance exists on how to accomplish this. The objective of this paper is to establish a framework and a blueprint to guide the operations of NGOs that provide outreach to build orthopaedic surgical capacity in LMICs. METHODS: We conducted a qualitative analysis of semistructured interviews with 16 orthopaedic surgeons and administrators located in 7 countries (6 LMICs) on the necessary domains for capacity-building; the analysis was guided by a literature review of capacity-building frameworks. We subsequently conducted a modified nominal group technique with a consortium of 10 U.S.-based surgeons with expertise in global surgical outreach, which was member-checked with 8 new stakeholders from 4 LMICs. RESULTS: A framework with 7 domains for capacity-building in global surgical outreach was identified. The domains included professional development, finance, partnerships, governance, community impact, culture, and coordination. These domains were tiered in a hierarchical system to stratify the level of capacity for each domain. A blueprint was developed to guide the operations of an organization seeking to build capacity. CONCLUSIONS: The developed framework identified 7 domains to address when building capacity during global orthopaedic surgical outreach. The framework and its tiered system can be used to assess capacity and guide capacity-building efforts in LMICs. The developed blueprint can inform the operations of NGOs toward activities that focus on building capacity in order to ensure a measured and sustained impact.

The presence of pneumonia was associated with a 2.621-day increase in hospitalization after adjusting for other variables (p < 0.001, 95% CI: 1.454 to 3.789). Conclusion: This study accentuates the clinical significance of postoperative pneumonia in femoral fracture patients, with a noted incidence of 10.8%. A notable association with older age, prolonged hospital stays, and ICU admissions was observed, underscoring the necessity of addressing this complication to improve patient outcomes and healthcare resource allocation.

Objective: Congenital defects/diseases Background: The rarity of ischiopagus tripus conjoined twins complicates the surgical separation, owing to the lack of cases and high complexity. We aim to report our experience in performing orthopedic correction for ischiopagus tripus twins. Case Report: A pair of 3-year-old conjoined boys presented with a fused body at the pelvis region and only 1 umbilicus. There were 2 legs separated by shared genitalia and an anus at the midline, and 1 fused leg, which could be felt and moved by both of the patients. The twins also shared internal organs of the bladder, intestine, and rectum, as visualized through angiography computerized tomography scan. After several team discussions with the institutional review board, the hospital ethics committee, and both parents, it was agreed to perform disarticulation of the fused third limb, followed by correction of the trunk alignment by pelvic closed wedge osteotomy and internal fixation. We successfully reconstructed the pelvis using locking plates and additional 3.5-mm cortical screws and 1.2-mm stainless steel wire. Conclusions: This report describes the presentation and surgical management of a case of ischiopagus tripus conjoined twins. It highlights the challenges involved in surgery and the importance of investigating these infants for other congenital abnormalities. Although surgical approaches for different sets of twins should be individually tailored, interventions aimed to provide optimal outcomes should consider ethical issues and parental/patient expectations. Even in situations in which the twins are inseparable, there is still room for surgical correction to be performed. [ABSTRACT FROM AUTHOR]

ABSTRACT Objective The purpose of this study was to evaluate the clinical and functional outcomes in patients who underwent surgical treatment for rotator cuff tears using open and arthroscopic techniques, and to evaluate the direct costs involved. Methods Retrospective cohort study with analysis of the data of patients who were referred to two private hospitals in Sao Paulo, Brazil for surgical repair of the rotator cuff from January 2018 to September 2019. Clinical outcomes were assessed using functional scores (SPADI and QuickDASH) and a quality of life questionnaire (EuroQoL). Procedure costs were calculated relative to each hospital’s costliest procedure. Results Data from 362 patients were analyzed. The mean patient age was 57 years (SD= 10.46), with a slight male predominance (53.9%). Arthroscopic procedures were more common than open procedures (95.6% versus 4.4%). Significant clinical improvement was reported in 84.8% of the patients. The factors associated with increased surgery costs were arthroscopic technique (increase of 29.2%), age (increase of 0.6% per year), and length of stay (increase of 18.9% per day of hospitalization). Conclusion Rotator cuff repair surgery is a highly effective procedure, associated with favorable clinical outcomes and improvement in life quality, and low rates of complications. Arthroscopic surgery tends to be costlier than open surgery.

Objective: This article reviews clinical implications and costs associated with orthopedic surgeries performed in inpatient versus outpatient settings. Methods: Studies spanning the publication period between 2000 and 2023 were included, exploring a variety of study designs. Results: Results indicate that outpatient surgeries are associated with lower rates of postoperative complications, shorter recovery times, and greater patient satisfaction, as well as with significantly lower direct and indirect costs. Analysis of postoperative complications suggests that factors such as the home recovery environment and early mobilization may contribute to improved clinical outcomes, corroborating existing literature on the safety and efficacy of outpatient surgeries. Faster recovery after outpatient surgeries was consistently observed, with patients returning to normal activities an average of two weeks earlier compared with those undergoing inpatient surgeries. The greater patient satisfaction with outpatient surgeries reflects the convenience of avoiding hospitalization, with less disruption to daily life and reduced anxiety associated with the hospital environment. In economic terms, outpatient surgeries have been shown to be a financially advantageous alternative, with reduced direct costs due to the lower hospital fees and nursing services required, as well as lower indirect costs due to reduced productivity loss and transportation expenses. Conclusion: Findings are particularly relevant in a context of increasing pressure to contain spending in the health system. Level of Evidence I; Systematic review of level I studies.

ObjectiveTo examine the efficacy of virtual reality (VR) to prepare surgical trainees for a pediatric orthopedic surgery procedure: pinning of a slipped capital femoral epiphysis (SCFE).DesignParticipants were randomly assigned to a standard, study guide (SG) group or to a VR training group. All participants were provided a technique video and SG; the VR group additionally trained via an Osso VR surgical trainer (ossovr.com) with real-time feedback and coaching from an attending pediatric orthopedic surgeon. Following training, participants performed a SCFE guidewire placement on a SawBones model embedded in a soft-tissue envelope (SawBones model 1161). Participants were asked to achieve "ideal placement" based on the training provided. Participants were evaluated on time, number of pin "in-and outs," penetration of the articular surface, angle between the pin and the physis, distance from pin tip to subchondral bone and distance from the center-center point of the epiphysis.SettingOrthopedic Institute for Children, Los Angeles, CA.ParticipantsTwenty fourth-year medical students, first- and second-year orthopedic residents without experience with the SCFE procedure.ResultsTwenty participants were randomized to SG (n = 10) or VR (n = 10). Average time to final pin placement was 19% shorter in VR group (706 vs 573 seconds, p = 0.26). When compared to SG, the VR group had, on average, 70% less pin in-and-outs (1.7 vs 0.5, p = 0.28), 50% less articular surface penetrations (0.4 vs 0.2, p = 0.36), and 18% smaller distance from pin tip to subchondral bone on lateral view (7.1 vs 5.8 mm, p = 0.42). Moreover, the VR group had a lower average angle deviation between pin and line perpendicular to the physis on coronal view (4.9° vs 2.5°, p < 0.05).ConclusionsVR training is potentially more effective than traditional preparatory methods. This pilot study suggests that VR training may be a viable surgical training tool, which may alleviate constraints of time, money, and safety concerns with resultant broad applicability for surgical education.

Cannabinoid compounds are being increasingly used as an analgesic adjuvant in the orthopedic population, but little data exist to either support or oppose this practice pattern. A review of all contemporary (2000-2020) studies on the use of cannabinoids in orthopedics is presented. Physicians and patients are optimistic that cannabinoids can decrease pain scores and perhaps opioid use; however, their application in orthopedics is not well characterized. In addition to the social stigma regarding the use of cannabis, there is limited high-quality evidence of the efficacy of cannabinoids in treating orthopedic-related pain. As cannabis becomes more accessible, well-designed trials are needed to better understand cannabinoids and guide orthopedic practice. [Orthopedics. 2022;45(6):e295-e302.].

BackgroundThe burden of traumatic musculoskeletal injuries falls greatest on low- and middle-income countries (LMICs). To help address this burden, organizations host over 6,000 outreach trips annually, 20% of which are orthopaedic. Monitoring post-surgical outcomes is critical to ensuring care quality; however, the implementation of such monitoring is unknown. The purpose of this review is to identify published follow-up practices of short-term orthopaedic surgery outreach trips to LMICs.MethodsWe completed a systematic review of Pubmed, Web of Science, EMBASE, and ProQuest following PRISMA guidelines. Follow-up method, rate, duration, and types of outcomes measured along with barriers to follow-up were collected and reported.ResultsThe initial search yielded 1,452 articles, 18 of which were eligible. The mean follow-up time was 5.4 months (range: 15 days-7 years). The mean follow-up rate was 65.8% (range: 22%-100%), the weighted rate was 57.5%. Fifteen studies reported follow-up at or after 3 months while eight studies reported follow-up at or after 9 months. Fifteen studies reported follow-up in person, three reported follow-up via phone call or SMS. Outcome reporting varied among mortality, complications, and patient-reported outcomes. The majority (75%) outlined barriers to follow-up, most commonly noting transportation and costs of follow-up to the patient.ConclusionsThere is minimal and heterogeneous public reporting of patient outcomes and follow-up after outreach trips to LMICs, limiting quality assessment and improvement. Future work should address the design and implementation of tools and guidelines to improve follow-up as well as outcome measurement to ensure provision of high-quality care.

Background/Aim. The number of pelvic traumas is increasing globally, mostly due to car accidents but also due to an increasing number of sports and recreational traumas. Tile C-type unstable pelvic trauma (TCUPT) is a kind of high-energy trauma that occurs during traffic accidents or accidents when falling from big heights. The aim of our study was to explore the application of the internal fixation (INFIX) system for the anterior pelvic ring (APR) with simultaneous application of sacroiliac screw (SS) INFIX of the posterior pelvic ring (PPR) in TCUPT. Methods. The subjects (89 of them in total) were recruited among patients with TCUPT from December 2020 to December 2023. A retrospective analysis of the subjects’ data was performed, after which the subjects were divided into two groups based on different therapeutic regimens applied: group A (INFIX system for the APR + SS IN-FIX of the PPR, n = 46) and group B (external fixator for the APR + SS INFIX of the PPR, n = 43). Results. In comparison with group B, group A had a shorter period before the commencement of the first activity after surgery, shorter fracture healing time and joint function recovery time, as well as length of hospital stay (t = 6.623, 4.796, 7.992, and 5.227, respectively, p < 0.05). The surgery duration and bleeding volume showed no significant differences between the two groups (t = 1.433, 1.123, respectively, p > 0.05). The fracture reduction outcomes were better in group A than in group B (Z = 2.058, p < 0.05). The incidence rate of complications was lower in group A than in group B (2.17% vs. 18.60%) (χ2 = 4.917, p < 0.05). Conclusion. For patients with TCUPT, the INFIX system for the APR with simultaneous application of SS INFIX of the PPR achieves good fracture reduction outcomes.

This paper presents a methodology and generalized motion framework for quantifying passive biomechanical stability and Range of Motion of human cadaveric specimens, using a position-controlled industrial robot and a wrist-mounted force/torque sensor. Many biomechanical studies on diarthrodial joints using human cadaveric specimens are published in the literature, using various test protocols and machines to apply the loading conditions. In these studies, laxity or mobility of the joints are quantified by measuring the magnitude of translations and rotations with respect to force and torque. The protocols and anatomical motions of the specimens are usually described high-level, textually, and from a medical perspective to a broad audience. The present paper aims to describe, from a technical perspective to a robotics audience, our method to perform biomechanical studies and how existing protocols can be replicated through parameterization using the existing textual descriptions. To accomplish this, we propose a generalized task space motion framework for performing biomechanical studies on diarthrodial joints. The generalization is made by defining the robot Tool Center Point at the cadaveric joint rotation center and aligning the specimen so the anatomical motions can be modeled in world frame or tool frame. The framework was successfully evaluated in a technical pilot study on the shoulder, using one cadaveric shoulder specimen and an established protocol from the literature. The specimen was tested in the intact state and in an injury state, with increased passive instability observed for the injury state compared to intact state.

Background/Purpose: Identifying patients at risk of prolonged opioid use after surgery prompts appropriate prescription and personalized treatment plans. The Skeletal Oncology Research Group machine learning algorithm (SORG-MLA) was developed to predict the risk of prolonged opioid use in opioid-naive patients after lumbar spine surgery. However, its utility in a distinct country remains unknown. Methods: A Taiwanese cohort containing 2795 patients who were 20 years or older undergoing primary surgery for lumbar decompression from 2010 to 2018 were used to validate the SORG-MLA. Discrimination (area under receiver operating characteristic curve [AUROC] and area under precision–recall curve [AUPRC]), calibration, overall performance (Brier score), and decision curve analysis were applied. Results: Among 2795 patients, the prolonged opioid prescription rate was 5.2%. The validation cohort were older, more inpatient disposition, and more common pharmaceutical history of NSAIDs. Despite the differences, the SORG-MLA provided a good discriminative ability (AUROC of 0.71 and AURPC of 0.36), a good overall performance (Brier score of 0.044 compared to that of 0.039 in the developmental cohort). However, the probability of prolonged opioid prescription tended to be overestimated (calibration intercept of −0.07 and calibration slope of 1.45). Decision curve analysis suggested greater clinical net benefit in a wide range of clinical scenarios. Conclusion: The SORG-MLA retained good discriminative abilities and overall performances in a geologically and medicolegally different region. It was suitable for predicting patients in risk of prolonged postoperative opioid use in Taiwan.

Taurolidine, known for its broad-spectrum antimicrobial properties and low toxicity, has shown promise in reducing infections in various surgical settings. However, it has not been extensively evaluated in orthopedic surgery. This study assessed the efficacy of taurolidine irrigation in reducing surgical site infections in patients undergoing ankle fracture surgery. A retrospective review was conducted for patients >20 years old who underwent ankle fracture surgery between March 2016 and March 2023, with follow-ups exceeding 6 months. Patients were classified into the following two groups: those who underwent normal saline (NS) irrigation and those who underwent taurolidine irrigation. Minor infections were defined as requiring additional oral antibiotics postoperatively, while major infections were characterized by hospitalization or reoperation due to infection within 3 months. Of 844 patients, 688 were included. The taurolidine group (n = 328) had a significant reduction in minor infections (7.3% vs. 22.5%, odds ratio = 0.410, p = 0.028) compared to the NS group (n = 360). Major infections were fewer in the NS group (1.2% vs. 0%, p = 0.051), but the number of cases was too small for reliable analysis. Taurolidine irrigation significantly reduces the occurrence of minor infections in ankle fracture surgeries when compared to normal saline irrigation.
