Introduction/UNASSIGNED:This study sought to investigate whether a validated trauma triage risk assessment tool can predict time to surgery and delay to surgery. Materials and Methods/UNASSIGNED:Patients aged 55 and older who were admitted for operative repair or arthroplasty of a hip fracture over a 3-year period at a single academic institution were included. Risk quartiles were constructed using Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA) calculations. Negative binomial and multivariable logistic regression were used to evaluate time to surgery and delay to surgery, respectively. Pairwise comparisons were performed to evaluate 30-day mortality rates and demonstrate the effectiveness of the STTGMA tool in triaging mortality risk. Results/UNASSIGNED:= .046). Discussion/UNASSIGNED:Patients in higher STTGMA quartiles encountered longer time to surgery, greater operative delays, and higher 30-day mortality. Conclusion/UNASSIGNED:Score for Trauma Triage in the Geriatric and Middle-Aged can quickly identify hip fracture patients at risk for a delay to surgery and may allow treatment teams to optimize surgical timing by proactively targeting these patients. Level of Evidence/UNASSIGNED:Prognostic Level III.

BACKGROUND:The number of individuals turning to cycling for physical activity and commuting has been expanding across the US. However, studies have demonstrated that when compared to motor vehicle accidents, cyclists in major cities have a significantly increased risk of injuries requiring hospitalizations. The purpose of this study was to assess if a correlation exists between the growing cyclist volume in a densely populated metropolitan city and prevalence of clavicle fractures requiring inpatient hospital admissions. HYPOTHESIS/OBJECTIVE:A correlation exists between the increased number of cyclists and the increasing number of clavicle fractures requiring inpatient hospital admissions. METHODS:Patients who sustained a clavicle fracture that required an inpatient admission were identified using the New York Statewide Planning and Research Cooperative System (SPARCS). The location of hospital admission was screened using New York City (NYC) hospital county codes, as only clavicle fractures presenting to NYC hospitals were included in the analysis. This study was exempt from Institutional Review Board (IRB) approval. Public transportation data was available through the Department of Transportation (DOT) and The Decennial Census. These databases are publicly available and are performed to assess if New Yorkers are using cycling as a mode of transportation. The cycling data included the following information in a given year: the number of people in NYC who use a bicycle as their primary mode of commuting to work, the number of daily cycling trips, total bicycle protected bike lane mileage, midtown Manhattan cycling counts and East River Bridge cycling counts. Spearman's correlation analysis was conducted between the numbers of patients with clavicle fractures per year and the described data for that specific year. Additionally, the number of bicycle-share program miles traveled per month and total number of cycling trips that month were obtained from the public bicycle-sharing program database from June 2013 through June 2015. Spearman's correlation analysis was conducted between the numbers of patients with clavicle fractures per month and total bicycle-sharing miles and trips traveled per month. RESULTS:The increasing daily cycling trips in NYC has a strong correlation with the increasing number of clavicle fractures in NYC (rs = .979, p < 0.001). The increasing use of a bicycle as transportation to work has a strong positive correlation with the increasing number of clavicle fractures in NYC (rs = .988, p < 0.001). There was a strong positive correlation between the mileage of bicycle lanes in NYC and the number of clavicle fractures (rs = .867, p = 0.001). A strong positive correlation exists between NYC clavicle fracture number and public bicycle-sharing miles (rs = .819, p < 0.001) and trips (rs = .811, p < 0.001). CONCLUSION/CONCLUSIONS:There are many physical benefits to cycling. Cycling, as a means of transportation, has been encouraged to decrease CO2 emissions from vehicular transportation. These benefits do not come without risks, as this study shows a correlation between increased cycling and clavicle fractures. CLINICAL RELEVANCE/CONCLUSIONS:Physicians and public health officials should be aware of the dangers of cycling in major cities in order to create safer routes for this environmentally beneficial route of transportation.

BACKGROUND/UNASSIGNED:The purpose of this study was to identify characteristic patterns of syndesmotic screw (SS) failure, and any effects on clinical outcome. METHODS/UNASSIGNED:A retrospective study was performed using a consecutive series of patients treated with open reduction and internal fixation with trans-syndesmotic screws for unstable ankle fractures with syndesmotic injury between 2015 and 2017. Patient demographics, fracture characteristics and classification, rates and patterns of trans-syndesmotic screw breakage, and backout were analyzed. Functional outcome was assessed using passive range of motion (ROM) and Maryland Foot Score (MFS). RESULTS/UNASSIGNED:> .07). CONCLUSION/UNASSIGNED:Syndesmotic screw breakage was common in younger, male patients. Despite similarities in ankle range of motion and clinical outcome scores to patients with intact screws, there was a trend towards more frequent screw removal. This information can be used to counsel patients pre- and postoperatively regarding the potential for screw failure and subsequent implant removal. LEVEL OF EVIDENCE/UNASSIGNED:Level III, retrospective case-control study.

Tibial plateau fractures can involve planes that require reduction and stabilization from a posterior approach. This includes posteromedial, posterolateral, and posterior column shear type injuries. This video outlines the prone posteromedial approach to the tibial plateau for posterior column fracture exposure, reduction, and fixation.

This video demonstrates a displaced radial shaft fracture repaired through a dorsal (Thompson) approach to the forearm. The patient is an 18-year-old man who sustained a left elbow dislocation and ipsilateral radial shaft fracture (OTA/AO: 22-B2) while playing basketball. The patient underwent a closed reduction of the elbow joint and was indicated for operative repair of the radius. Ultimate fixation included a compression plate and nonlocking screws through a dorsal approach to the radius. Anatomic reduction and stable fixation was obtained. The posterior interosseus nerve was identified and protected throughout the procedure. A dorsal (Thompson) approach to a radial shaft fracture is advantageous for fractures involving the proximal and middle-third of the radius. This approach can also be used when there is soft tissue damage (open wounds) on the dorsal aspect, which require debridement.

INTRODUCTION/BACKGROUND:Students seek gap years to enhance knowledge and improve chances of professional success. Although many institutions offer research opportunities, no studies have examined outcomes after these experiences. This study evaluates a dedicated year of orthopaedic research on a cohort's ultimate orthopaedic surgery match rate. METHODS:From 2001 to 2018, 129 learners spent a year with our Department of Orthopedic Surgery at a major academic medical center. The students were either completing a gap year after college, during or after medical school, or after an unsuccessful match. Participants were asked to respond to a survey, which included demographics, educational information, and metrics related to the program. For the subcohort of students who ranked orthopaedic surgery, the match rate was compared with the mean for the US orthopaedic surgery match rates from 2006 to 2018 using a chi-square analysis. In addition, a Mann-Whitney U test was used to compare the number of publications before and after the year. RESULTS:One hundred three students (80%) returned completed questionnaires. Of all learners who applied to and ranked orthopaedic surgery, 91% matched into an orthopaedic surgery residency program. These results compared favorably with the US orthopaedic match from 2006 to 2018 (67.9%; P < 0.001), despite a 4-point lower United States Medical Licensing Examination (USMLE) Step 1 score for the research cohort. Finally, the research cohort had a greater percentage of women (23%) and minorities (40%) than the proportion of woman and minority practicing orthopaedic surgeons. CONCLUSION/CONCLUSIONS:Students who completed a gap year in research matched into orthopaedics at a higher rate than the national average, despite a lower Step score. Mentors may also target traditionally underrepresented groups to help increase the pool of diverse applicants.

To determine the functional outcome and complications following dorsal plating for unstable fractures of the distal radius. We searched our IRB-approved Distal Radius Fracture Databases and identified all patients who were treated with a dorsally applied plate. Thirty-four distal radius fractures in 33 patients with a mean age of 50 years and average follow-up of 14 months were treated with a dorsal locking plate from 2007 to 2015. Fifteen and six patients had dorsal shearing fracture pattern and delayed presentation, respectively. There were no loss of reduction, malunion, or nonunion. Average VAS pain score was 2.1/10. Eight patients (23%) required hardware removal, one of which was due to extensor tendon rupture (3%) and five due to extensor tendon irritation (15%). Dorsal locked plating of distal radius fractures with newer low-profile implants is a viable option for particular fractures types, such as the dorsal rim shear type fractures.

OBJECTIVES/OBJECTIVE:To examine one health system's response to the essential care of its hip fracture population during the COVID-19 pandemic and report on its effect on patient outcomes. DESIGN/METHODS:Prospective cohort study SETTING:: Seven musculoskeletal care centers with New York City and Long Island. PATIENTS/PARTICIPANTS/METHODS:138 recent and 115 historical hip fracture patients. INTERVENTION/METHODS:Patients with hip fractures occurring between February 1, 2020 and April 15, 2020 or between February 1, 2019 and April 15, 2019 were prospectively enrolled in an orthopedic trauma registry and chart reviewed for demographic and hospital quality measures. Patients with recent hip fractures were identified as COVID positive (C+), COVID suspected (Cs) or COVID negative (C-). MAIN OUTCOME MEASUREMENTS/METHODS:Hospital quality measures, inpatient complications and mortality rates. RESULTS:Seventeen (12.2%) patients were confirmed C+ by testing and another 14 (10.1%) were suspected (Cs) of having had the virus but were never tested. The C+ cohort, when compared to Cs and C- cohorts, had: an increased mortality rate (35.3% vs 7.1% vs 0.9%), increased length of hospital stay, a greater major complication rate and a greater incidence of ventilator need postoperatively. CONCLUSIONS:COVID-19 had a devastating effect on the care of hip fracture patients during the pandemic. Although practice patterns generally remained unchanged, treating physicians need to understand the increased morbidity and mortality in hip fracture patients complicated by COVID-19. LEVEL OF EVIDENCE/METHODS:Prognostic Level III. See Instructions for Authors for a complete description of Levels of Evidence.
