Introduction: Venous thromboembolism following orthopedic trauma surgery remains prevalent despite prophylaxis being a standard of care. Enoxaparin injection is a commonly utilized prophylaxis regimen among high-risk patients. Patient-reported rates of nonadherence and barriers to enoxaparin use are not described in the literature. A better understanding of these barriers and their impact on adherence to post-discharge prophylaxis regimens may shed light on persistent outcomes gaps., Materials and Methods: Semi-structured interviews were administered to adult patients prescribed prophylactic enoxaparin and presenting to orthopedic surgery outpatient clinic at an urban level 1 trauma center for a post-operative appointment following traumatic injury from April to July 2023. Patients self-reported their age, gender, race, and mobility. Inductive thematic analysis with three-reviewer consensus identified common barriers among responses. Adherence rates were calculated by dividing patients' estimated number of missed doses over total prescribed doses at the point of inquiry., Results: We identified 154 eligible patients through chart review, and 50 enrolled and interviewed. Participants had a mean age of 37 years. Of 50 participants, 20 identified as female; 25 identified as Black or African American, 16 as White, 5 as Hispanic, 2 as Asian, and 2 as multiracial. Twenty-one participants were non-ambulatory at time of interview. Mean and median patient-reported adherence were 64.5 % (SD 35.5) and 70.5 % (IQR 33-100) respectively. Five patients reported complete nonadherence, while 17 patients reported perfect adherence. Every participant reporting complete nonadherence identified as Black or African American, as compared to 8 out of 17 reporting perfect adherence. Despite acknowledging a twice-daily prescription, 17 patients reported once-daily rather than twice-daily use. Inductive thematic analysis revealed the following six barriers to prophylaxis adherence (number of participants reporting): Inconvenience (18 patients), Pain (16), Fear (12), Acquisition (7), Bruising (7), and Mechanism (7). Altogether, 40 patients endorsed at least one barrier to adherence., Discussion & Conclusions: Most patients face barriers to adherence with post-discharge prophylactic enoxaparin, and the resultant rates of adherence are low. This may contribute to persistent outcomes gaps in the orthopedic trauma population despite prophylaxis standards. Changes in prescribing patterns and patient engagement techniques may improve post-operative thromboembolic outcomes., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Ltd.

Background: There is a select number of massive-volume, high-acuity trauma centers (HACs) in the United States. Expertise in polytrauma care has been associated with improved mortality in general surgery trauma, though has not been investigated in orthopaedic trauma. With complex polytrauma proficiency comes the inherent risk of intensive care, complications, and prolonged inpatient stays, without a commensurate increase in allocated resources. The purpose of this study was to compare mortality, complications, and length of stay in polytraumatized orthopaedic patients treated at HACs vs. low-acuity trauma centers (LACs)., Methods: The National Trauma Data Bank was queried for orthopaedic injuries with injury severity score (ISS)>15 and mortality, complications, hospital length of stay, ICU length of stay, ventilation duration, and demographics. Hospitals where at least 13% (median percentage of patients with ISS > 15 admitted to all hospitals) of total admissions had an ISS>15 were classified as HAC; all others were LACs., Results: HACs admitted 86.8% of 28,314 patients with ISS>15. On univariate analysis, patients at HACs have 16% decreased odds of in-hospital mortality vs. LACs (p=0.005); the effect increased to 27% (p=0.002) on multivariate analysis. Patients at HACs have 63% greater odds of ICU admission (p<0.001), 48% higher odds of ventilatory support (p=<0.001), 38% increased odds of unplanned reoperation (p=0.007), and 37% increased odds of medical complications (p<0.001). On multivariate analysis, secondary outcome measures showed no significant difference between HACs and LACs. Patients at HACs had 2.8 days longer length-of-stay (p<0.001)., Conclusion: Severely injured orthopaedic trauma patients have decreased mortality at HACs, despite having a higher average ISS and a higher prevalence of obesity and active smoking. While there is a higher incidence of ICU admission, mechanical ventilation, complications, and unplanned reoperation on univariate analysis, correction for ISS and patient factors enhances the effect of HACs on mortality, but removes the effect on secondary measures. Thus, HACs are life-saving institutions for polytraumatized orthopaedic patients, and the known resource demand of these hospitals is supported by their favorable outcome profile., Level of Evidence: IV., (Copyright © 2020.

Purpose: Malnutrition is known to negatively affect outcomes after arthroplasty, hip fracture, and spine surgery. Although distal radius fracture surgery may be considered in a similar patient cohort, the effect of malnutrition in this scenario is unknown. We hypothesized that admission serum albumin level, as a marker for malnutrition, would correlate with the rate of postoperative complications following surgery for distal radius fracture., Methods: We performed a retrospective cohort study of the American College of Surgeons National Surgery Quality Improvement database. Patients undergoing open reduction and internal fixation of a distal radius fracture were identified using Current Procedural Terminology codes. We excluded patients who were septic at presentation, were multiply injured, or had open fractures. We collected patient demographics, length of stay, 30-day complications, reoperation, and readmission rates. We performed multivariable linear regression analysis controlling for age, sex, body mass index, operative time, discharge destination, and modified Frailty Index score., Results: We identified 1,989 patients (mean age, 56 years; range, 18-90 years) with available albumin levels, and 14.7% had hypoalbuminemia (albumin, < 3.5 g/dL). Multivariable regression revealed that malnourished patients had higher rates of postoperative complications (6.5% vs 1.3%; odds ratio [OR] 4.88; 95% confidence interval [95% CI], 2.47-9.66). Specifically, these patients had increased rates of Clavien-Dindo IV (life-threatening) complications (2.4% vs 0%), readmission (7.2% vs 2%; OR, 3.37; 95% CI, 1.88-6.03), and mortality (1.7% vs 0.1%; OR, 9.23; 95% CI, 1.55-54.87). Malnourished patients had significantly longer length of stay (3.55 vs 0.73 days). Albumin concentration was inversely associated with risk of death (OR, 0.12; 95% CI, 0.03-0.52)., Conclusions: Malnutrition, indicated by albumin less than 3.5 g/dL, is a powerful predictor of uncommon, but important, postoperative complications, including mortality, following surgery for distal radius fracture. Evaluation of preoperative albumin level may, therefore, help surgeons provide individualized counseling and more accurately stratify the risk of patients., Type of Study/level of Evidence: Prognostic II., (Copyright © 2019 American Society for Surgery of the Hand.

Background: As morbidity and mortality from traumatic orthopaedic injuries continues to rise, increased research is being conducted on how to best predict complications in at risk patients. Recently, frailty indices have been validated in a variety of surgical subspecialties as predictors of morbidity and mortality. However, the vast majority of research has been conducted on geriatric patient populations, with little evidence on patients who are chronologically young. The purpose of this study was to evaluate the role of a modified frailty index (mFI) in predicting mortality and complications after pelvis, acetabulum, and lower extremity trauma in patients of all ages., Methods: The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was queried from 2005 to 2014 for all patients who underwent surgery for pelvis, acetabulum, and lower extremity trauma. The sample size was divided into geriatric (age ≥ 60) and young (age < 60) cohorts. The mFI score was calculated for each patient. Bivariate analysis was performed using logistic regression and a chi-square test to determine the relationship between mFI and both primary and secondary outcomes while adjusting for age. Univariate analysis and multivariate analyses were performed. All analyses were done using SAS 9.4 (Cary, NC) and a p < 0.05 was considered significant., Results: 56,241 patients were identified to have undergone surgery for pelvis, acetabulum, or lower extremity trauma. 28% of patients were identified under the age of 60. In the young cohort, mFI was a strong predictor of thirty-day mortality (OR 11.02, 95% CI 6.26-19.39, p < 0.001). With regards to Clavien-Dindo grade IV complications, MFI is also a strong predictor in the young cohort (OR 28.82, 95% CI 16.05-51.77, p < 0.001)., Conclusion and Relevance: The mFI score was a significant predictor of morbidity and mortality in chronologically young orthopaedic trauma patients. The use of the mFI score can provide an individualized risk assessment to interdisciplinary teams for perioperative counseling and to improve outcomes., (Copyright © 2018 Elsevier Ltd.

Objectives: To describe differences in follow-up compliance and emergency department (ED) visits between ballistic and non-ballistic operative lower extremity fracture patients., Design: Retrospective study., Setting: Urban level 1 trauma center., Patients/participants: Patients age ≥18 years with ≥1 tibia or femur fractures treated with ORIF or intramedullary nailing (IMN) between September 1, 2013 and August 31, 2015., Main Outcome Measure: A compliance fraction calculated as ([number of attended follow-up visits] / [number of attended follow-up visits + number of missed follow-up visits]) and ED visits in the post-operative period., Results: 612 patients were studied. Patients with ballistic lower extremity fractures had a younger mean age (30.8 years v. 41.6 years; p < 0.0001); a shorter length of stay (5.00 days v. 8.00 days; p < 0.0001); and were more likely to be male (92.6% v. 68%; p < 0.0001) and African-American (90.1% v. 63.1%; p < 0.0001) when compared to non-ballistic long bone injuries. Increased follow-up compliance (defined as a compliance fraction ≥0.75) was associated with having a non-ballistic fracture (OR 1.73, 1.13-2.64; p = 0.01), not having an ED visit (OR 2.08, 1.30-3.33; p = 0.002), and being female (OR 1.82, 1.27-2.61; p = 0.001). Increased ED utilization (≥ 1 ED visit) was associated with ballistic mechanism (OR 1.95, 1.20-3.16; p = 0.006), a low follow-up compliance fraction (OR 2.08, 1.30-3.33; p = 0.0019), homelessness (OR 3.91, 1.53-9.98; p = 0.006), and African-American race (OR 2.26, 1.26-4.05; p = 0.05). Scheduling a specific follow-up visit on the discharge summary did not predict higher compliance (OR 1.51, 0.98-2.33; p = 0.06). Conversely, the lack of a specific follow-up visit scheduled on the discharge summary did not predict ED utilization (OR 0.63, 0.34-1.17; p = 0.14)., Conclusion: The results of this study demonstrate that increased utilization of the ED was associated with ballistic fractures, homelessness, decreased clinic compliance, and African American race. Furthermore, patients with non-ballistic injuries, women, and those without any ED visit were more likely to have higher outpatient clinic compliance., (Copyright © 2018 Elsevier Ltd.

Purpose: Compared with cast treatment, surgery may expose patients with distal radius fractures to undue risk. Surgical intervention in this cohort may offer less benefit than previously thought and appropriate patient selection is imperative. The modified Frailty Index (mFI) predicts complications after other orthopedic surgeries. We hypothesized that this index would predict, and might ultimately prevent, complications in patients older than 50 years with distal radius fractures., Methods: We retrospectively reviewed the American College of Surgeons-National Surgery Quality Improvement Program (ACS-NSQIP) database, including patients older than 50 years who underwent open reduction and internal fixation of a distal radius fracture. A 5-item mFI score was then calculated for each patient. Postoperative complications, readmission and reoperation rates, as well as length of stay (LOS) were recorded. Bivariate and multivariable statistical analysis was then performed., Results: We identified 6,494 patients (mean age, 65 years). Compared with patients with mFI of 0, patients with mFI of 2 or greater were nearly 2.5 times as likely to incur a postoperative complication (1.7% vs 7.4%). Specifically, the rates of Clavien-Dindo IV, wound, cardiac, and renal complications were increased significantly in patients with mFI of 2 or greater. In addition, as mFI increased from 0 to 2 or greater, 30-day reoperation rate increased from 0.8% to 2.4%, 30-day readmission from 0.8% to 4.6%, and LOS from 0.5 days to 1.44 days. Frailty was associated with increased complications as well as rates of readmission and reoperation even when controlling for demographic data, LOS, and operative time. Age alone was not significantly associated with postoperative complications, readmission, reoperation, or LOS., Conclusions: A state of frailty is highly predictive of postoperative complications, readmission, reoperation, and increased LOS following open reduction and internal fixation of distal radius fractures. Our data suggest that a simple frailty evaluation can help inform surgical decision making in patients older than 50 years with distal radius fractures., Type of Study/level of Evidence: Prognostic II., (Copyright © 2018 American Society for Surgery of the Hand.

Objective: The burgeoning elderly population calls for a robust tool to identify patients with increased risk of mortality and morbidity. This paper investigates the utility of the MFI as a predictor of morbidity and mortality in orthopaedic trauma patients., Design: Retrospective review of the NSQIP database to identify patients age 60 and above who underwent surgery for pelvis and lower extremity fractures between 2005 and 2014., Main Outcomes and Measures: For each patient, an MFI score was calculated using NSQIP variables. The relationship between the MFI score and 30-day mortality and morbidity was determined using chi-square analysis. MFI was compared to age, American Society of Anesthesiologists physical status classification, and wound classifications in multiple logistic regression., Results: Study sample consisted of 36,424 patients with 27.8% male with an average age of 79.5 years (SD 9.3). MFI ranged from 0 to 0.82 with mean MFI of 0.12 (SD 0.09). Mortality increased from 2.7% to 13.2% and readmission increased from 5.5% to 18.8% with increasing MFI score. The rate of any complication increased from 30.1% to 38.6%. Length of hospital stay increased from 5.3days (±5.5days) to 9.1days (±7.2days) between MFI score 0 and 0.45+. There was a stronger association between 30-day mortality and MFI (aOR for MFI 0.45+: 2.6, 95% CI: 1.7-3.9) compared to age (aOR for age: 1.1, 95% CI: 1.1-1.1) and ASA (aOR 2.5, 95% CI: 2.3-2.7)., Conclusions and Relevance: MFI was a significant predictor of morbidity and mortality in orthopaedic trauma patients. The use of MFI can provide an individualized risk assessment tool that can be used by an interdisciplinary team for perioperative counseling and to improve outcomes., (Copyright © 2017.

Background: Resident selection is integral to the graduate medical educational process and the future of our profession. There is no consensus among residency directors as to how to systematically and consistently screen and select applicants who would perform well as residents. The purpose of this study was to introduce and assess a high volume application screening tool and semistructured interview process., Methods: This study took place in an academic orthopedic surgery department over 2 years (2013-2014). Overall, 1382 applications were screened in 7 categories, with a maximum score of 100. A total of 14 faculty reviewed applications; 218 interviews were offered; 165 applicants accepted the interview. Overall, 4 interview domains (cognitive, affective, activities, and theme), and an impression score were ranked from 1 (Exceptional) to 6 (Concern). Each room had an assigned "theme" (ethics, affective, cognitive, research, and "fit") with standardized questions. A summary score was generated of all scores to determine the preliminary rank list; the final rank list was determined after group discussion. Correlation between preliminary rank, final rank, and screening scores were assessed., Results: The average screening score was 62.5 (range: 0-100, median = 64). The average interview score was 69.5 (range: 32.24-95.0). Final rank lists correlated most highly with initial rank (0.912, p < 0.001), impression (0.847, p < 0.001), and affective domain (0.834, p < 0.001). Cognitive domain (0.628, p < 0.001) and screening scores (0.264, p < 0.001) less highly correlated with final rank position., Conclusions: A systematic approach was used to screen and evaluate a large number of orthopedic surgery applicants. Our system demonstrated excellent feasibility, reliability, and predictability for the final rank list., (Copyright © 2016 Association of Program Directors in Surgery. Published by Elsevier Inc.

Femoroacetabular impingement (FAI) has been recently recognized as a cause of hip pain, labral and chondral pathology, early osteoarthritis, and decreased athletic performance. Historically, treatment for FAI consisted of an open approach with surgical dislocation. It has been suggested that the operative trauma sustained during the open procedure may make it difficult for high-level athletes to return to play. As a result, an arthroscopic approach to treat FAI has been developed. The purpose of this article is to describe the arthroscopic technique for the treatment of cam and pincer-type hip impingement.

Although hip arthroscopic techniques have been developed and evolved over the last 5 to 10 years to help active athletes, the mechanisms of athletic hip injuries across various sports are not well understood. The purpose of this article is to review the literature related to the osseous and ligamentous support as well as the neuromuscular control strategies associated with hip joint mechanics. The neuromuscular contributions to hip stability and mobility with respect to gait will be provided because this data represents the largest body of knowledge regarding hip function. Further, this article will present and describe probable mechanisms of injury in sporting activities most often associated with hip injury in the young athlete.

In the past, arthroscopic technique for the treatment of a torn acetabular labrum was limited to simple debridement of the torn tissue. However, due to recent advancements in the understanding of the function of the labrum, it has been suggested that labral repair can be beneficial. The purpose of this article is to report a new technique for arthroscopic rim trimming of pincer-type femoroacetabular impingement and labral repair through the lateral arthroscopic portal.
