INTRODUCTION/BACKGROUND:In city hospitals, subway-related traumatic amputations are a frequent pattern of injury, however there is a paucity of literature on this specific injury pattern. The purpose of this study was to describe the epidemiology of subway-related traumatic amputations, as well as compare them to non-subway traumatic amputations. PATIENTS AND METHODS/METHODS:Retrospective review was performed at a single Level-1 trauma center in a metropolitan area. All patients who sustained a traumatic lower-extremity amputation over a seven-year period were included. Demographics, injury, treatment-related information, and complications were collected. Subway and non-subway traumatic amputations were statistically compared. Cohorts were further subdivided into above-knee amputations (AKAs) and below-knee amputations (BKAs) for statistical comparison. RESULTS:Fifty-seven patients sustained 72 traumatic lower-extremity amputations, including 64 subway-related amputations. Fifteen patients with bilateral lower-extremity amputations all had subway-related injuries. Patients with subway-related injuries were more likely to have a history of alcohol use disorder (58.1 % vs. 0 %; P = 0.002), and experienced longer stays in the intensive care unit (ICU) (8.9 vs. 3.6 days; P = 0.006). Twenty-four amputations (33.3 %) were complicated by wound infection during the initial hospitalization, with wound cultures growing a variety of organisms, most frequently Enterococcus species and Enterobacter cloacae. When subway injuries were separated by AKAs and BKAs, patients with AKAs underwent more irrigation and debridement procedures on average (10.3 vs. 5.8; P = 0.006), had a higher rate of wound infections (58.8 % vs. 25.0 %; P = 0.018), and had longer hospital stays (50.4 vs. 32.2 days; P = 0.047). CONCLUSION/CONCLUSIONS:Subway-related amputations are associated with longer ICU stays and a history of alcohol use disorder compared to non-subway traumatic amputations. Approximately 1/3 of these patients are expected to develop a wound infection, with Enterococcus and Enterobacter species being the most commonly identified organisms. Further research into high-energy, traumatic amputations, including subway injuries, may help improve prognostication of patient outcomes, identify potential in-hospital complications, and proactively direct differences in care compared to the standard for non-subway-related amputations. LEVEL OF EVIDENCE/METHODS:Prognostic Level III.

INTRODUCTION/BACKGROUND:Racial and ethnic disparities in orthopaedic surgery are well documented. However, the extent to which these persist in fracture care is unknown. This study sought to assess racial disparities in the postoperative surgical and medical management of patients after diaphyseal tibia fracture fixation. METHODS:Patients with surgically treated tibial shaft fractures from October 1, 2015, to December 31, 2020, were identified in the MarketScan® Medicaid Database. Exclusion criteria included concurrent fractures or amputation. Outcomes included 2-year postoperative complications, reoperation rates, and filled prescriptions. Surgically-treated Black and White cohorts were propensity-score matched using nearest-neighbor matching on patient demographics, comorbidities, fracture pattern and severity, and fixation type. Chi-square tests and survival analyses (Kaplan-Meier and Cox proportional hazard models) were conducted. RESULTS:5,472 patients were included, 2,209 Black and 3,263 White patients. After matching, 2,209 were retained in each cohort. No significant differences in complication rates were observed in the matched Black vs White cohorts. Rates of reoperation, however, were significantly lower in Black as compared to White patients (28.5 % vs. 35.5 % rate, risk difference = 7.0 % (95 % confidence interval (CI): 4.2 % to 9.7 %)). Implant removal was also significantly lower in Black (17.9 %) vs. White (25.1 %) patients (Risk difference = 7.2 %, (95 %CI: 4.8 % to 9.6 %)). The adjusted hazard ratio comparing the reoperation rate in Black versus White patients was 0.77 (95 %CI: 0.69-0.82, p < 0.0001). Significantly lower proportions of Black vs White patients filled at least one prescription for benzodiazepine, antidepressants, strong opiates, or antibiotics at every time point post-index. DISCUSSION/CONCLUSIONS:Fewer resources were used in post-operative management after surgical treatment of tibial shaft fractures for Black versus White Medicaid-insured patients. These results may be reflective of the undertreatment of complications after tibia fracture surgery for Black patients and highlight the need for further interventions to address racial disparities in trauma care.

OBJECTIVES/OBJECTIVE:The objective of this study was to ascertain outcome differences after fixation of unstable rotational ankle fractures allowed to weight-bear 2 weeks postoperatively compared with 6 weeks. DESIGN/METHODS:Prospective case-control study. SETTING/METHODS:Academic medical center; Level 1 trauma center. PATIENT SELECTION CRITERIA/UNASSIGNED:Patients with unstable ankle fractures (OTA/AO:44A-C) undergoing open reduction internal fixation (ORIF) were enrolled. Patients requiring trans-syndesmotic fixation were excluded. Two surgeons allowed weight-bearing at 2 weeks postoperatively (early weight-bearing [EWB] cohort). Two other surgeons instructed standard non-weight-bearing until 6 weeks postoperatively (non-weight-bearing cohort). OUTCOME MEASURES AND COMPARISONS/UNASSIGNED:The main outcome measures included the Olerud-Molander questionnaire, the SF-36 questionnaire, and visual analog scale at 6 weeks, 3 months, 6 months, and 12 months postoperatively and complications, return to work, range of ankle motion, and reoperations at 12 months were compared between the 2 cohorts. RESULTS:One hundred seven patients were included. The 2 cohorts did not differ in demographics or preinjury scores ( P > 0.05). Six weeks postoperatively, EWB patients had improved functional outcomes as measured by the Olerud-Molander and SF-36 questionnaires. Early weight-bearing patients also had better visual analog scale scores (standardized mean difference -0.98, 95% confidence interval [CI] -1.27 to -0.70, P < 0.05) and a greater proportion returning to full capacity work at 6 weeks (odds ratio = 3.42, 95% CI, 1.08-13.07, P < 0.05). One year postoperatively, EWB patients had improved pain measured by SF-36 (standardized mean difference 6.25, 95% CI, 5.59-6.92, P < 0.01) and visual analog scale scores (standardized mean difference -0.05, 95% CI, -0.32 to 0.23, P < 0.01). There were no differences in complications or reoperation at 12 months ( P > 0.05). CONCLUSIONS:EWB patients had improved early function, final pain scores, and earlier return to work, without an increased complication rate compared with those kept non-weight-bearing for 6 weeks.

INTRODUCTION/UNASSIGNED:African American, Hispanic, Asian, and Pacific Islanders are groups who are underrepresented in medicine (URM groups). Similarly, although women comprise more than 50% of medical students in the United States, women comprise a smaller percentage of all orthopaedic surgery trainees. Therefore, underrepresented in orthopaedics (URiO) represents the URM groups and women. The purpose of this study is to examine the impact of specific steps to recruit a qualified, diverse trainee complement within a single academic orthopaedic surgery residency program between 2000 and 2023. We aim to explore changes in the representation of URiO during this period as well as explore the strategies and programs implemented by the department that may have impacted recruitment of a diverse complement of trainees. METHODS/UNASSIGNED:Match lists from a large, academic, orthopaedic surgery residency between 2000 and 2023 were collected and reviewed for racial and gender data. Match lists were then divided into 6-year quantiles to identify any trends in the recruitment of URiO students. Self-reported racial and gender data from Electronic Residency Application Service applicant reports and the Accreditation Council for Graduate Medical Education (ACGME) data books between 2018 and 2022 were collected and reviewed. In addition, the department's strategies implemented during the study period with the goal of enhancing URiO exposure to orthopaedic surgery were also explored. RESULTS/UNASSIGNED:The department implemented proactive strategies to increase exposure to orthopaedic surgery for URiO students. An increase in URiO representation was noted between 2000 and 2023 with Hispanic, Black/African American, and Native Hawaiian/Pacific Islander resident representation increasing by 5%, 11%, and 1%, respectively. In addition, women representation increased by 27% between 2000 and 2023. The overall attrition rate among URiO residents was 1% with only one resident not completing the program. Self-reported racial and gender data from ACGME data books demonstrated that Black/African American, Hispanic, and Native Hawaiian/Pacific Islander residents comprised 5%, 4%, and 0.04%, respectively, of orthopaedic surgery residents between 2018 and 2022. CONCLUSIONS/UNASSIGNED:These results provide insight for other programs to use similar strategies to potentially improve recruitment, retain, and provide support to URiO residents.

OBJECTIVE:To assess the effectiveness of a multimodal analgesic regimen containing "safer" opioid and non-narcotic pain medications in decreasing opioid prescriptions following surgical fixation in orthopedic trauma. DESIGN/METHODS:Retrospective cohort study. SETTING/METHODS:One urban, academic medical center. SUBJECTS/METHODS:Traumatic fracture patients from 2018 (848) and 2019 (931). METHODS:In 2019 our orthopedic trauma division began a standardized protocol of post-operative pain medications that included: 50 mg of tramadol four times daily, 15 mg of meloxicam once daily, 200 mg gabapentin twice daily, and 1 g of acetaminophen every 6 hours as needed. This multimodal regimen was dubbed the "Lopioid" protocol. We compared this protocol to all patients from the prior year who followed a standard protocol that included Schedule II narcotics. RESULTS:Greater mean MME were prescribed at discharge from fracture surgery under the standard protocol compared to the Lopioid protocol (252.3 vs 150.0; p < 0.001) and there was a difference in the type of opioid medication prescribed (p < 0.001). There was a difference in the number of refills filled for patients discharged with opioids after surgical treatment between standard and Lopioid cohorts (0.31 vs 0.21; p = 0.002). There was no difference in the types of medication-related complications (p = 0.710) or the need for formal pain management consults (p = 0.199), but patients in the Lopioid cohort had lower pain scores at discharge (2.2 vs 2.7; p = 0.001). CONCLUSIONS:The Lopioid protocol was effective in decreasing the amount of Schedule II narcotics prescribed at discharge and the number of opioid refills following orthopedic surgery for fractures.

Segmental bone defects (SBD) are difficult to treat, requiring a comprehensive understanding of the bone and soft tissue injury. Defect size, fracture characteristics, and local and systemic biology all help dictate treatment options. Bone grafting with autograft or allograft, Masquelet technique, and bone transport with external or internal fixation can all be used successfully in the correct patient. When deciding on the best treatment option and addressing any complications throughout the process, it is important to always keep in mind the three principles of bone healing: sterility, stability, and biology. The goal of this review is to present the history of treatment for critical SBD, including the indications and challenges that have been addressed and current and emerging treatment options.

BACKGROUND:The purpose of this study is to describe a Level 1 Trauma Center's orthopedic response to the COVID-19 pandemic, and to compare outcomes of acute fracture patients pre-COVID versus during the COVID-19 pandemic. METHODS:All inpatient fracture cases performed over a 5-month period were identified and retrospective chart review performed. Patients were divided into pre- and COVID-era groups based on when surgery was performed relative to March 16, 2020 (the date elective operations were ceased), and groups were statistically compared. Patients with a COVID test result were further sub-divided into COVID negative and positive groups, and statistically compared. Statistical analysis was performed using independent t-test for continuous variables and chi-square analysis for categorical variables. RESULTS:One hundred and nineteen patients were identified, 38% females with average age of 58 years. Average length of stay was 7 days with average time from injury to surgery of 3 days and average time from admission to surgery of 1.3 days. Overall in-hospital complication rate was 29.4%, and 30-day mortality and readmission rates were 2.5% and 5%, respectively. Sixty-nine patients comprised the pre-COVID group, and 50 in the COVID-era group. There was no significant difference with respect to length of stay, time from injury to surgery, time from admission to surgery, need for post-operative ICU stay, in-hospital complication rate, 30-day mortality rate and 30-day readmission rate. Thirty-four patients had COVID testing, with 24 negative and 10 positive. COVID-positive patients had longer time from injury to surgery (8.5 days vs. 2 days, p = 0.003) and longer time from admission to surgery (2.7 days vs. 1.2 days, p = 0.034). While more COVID-positive patients required ICU admission post-operatively (60% vs. 21%, p = 0.036), there was no difference in overall complication rate. CONCLUSIONS:Orthopedic care of acute fracture patients was not affected by a global pandemic. The response of our Level 1 Trauma Center's orthopedic department can guide other hospitals if and when new surges in COVID cases arise, in order to prevent compromising appropriate orthopedic care. LEVEL OF EVIDENCE/METHODS:Prognostic III.

Diversity has multiple dimensions, and individuals' interpretation of diversity varies broadly. The Orthopaedic Trauma Association (OTA) leadership recognized the need to address issues of diversity within the organization and appointed the OTA Diversity Committee in 2020. The OTA Diversity Committee has produced a statement that was confirmed by the OTA's board of directors reflecting the organization's position on diversity: "The OTA promotes and values diversity and inclusion at all levels with the goal of creating an environment where every member has the opportunity to excel in leadership, education, and culturally-competent orthopaedic trauma care." The OTA Diversity Committee surveyed its 1907 OTA members in the United States and Canada to assess its membership's attitudes toward and interpretation of this important topic.
