INTRODUCTION/BACKGROUND:The purpose of this study was to assess whether language affects patient time to surgery following hip fractures. METHODS:Patients >55 years who underwent operative hip fracture repair between 2014 and 2021 were reviewed for demographics, language, hospital quality measures, and outcomes. Patients were split into English (E) or non-English (NE) cohorts based on their primary language. RESULTS:A total of 1880 patients (1477 E, 403 NE) were included. The E cohort was younger, had lower body mass index, and lower American Society of Anesthesiology Score (P < .01). The E cohort had more White patients (P < .01), whereas the NE cohort had more Hispanic, Asian, and patients with unknown backgrounds (P < .01 for all). At baseline, the E cohort patients were more likely to be community ambulators (P < .01). There were no differences in time to surgery or length of stay (P > .05). CONCLUSION/CONCLUSIONS:Despite poorer baseline medical conditions, NE speaking patients received similar care to English speakers highlighting the importance of an effective standardized protocol with readily available translation services. LEVEL OF EVIDENCE/METHODS:Level III, Retrospective cohort study.

In January 2024, New York University Langone Orthopedic Surgery achieved a significant milestone with the first all-women team, from chief residents to interns, at Bellevue Hospital. In a field still dominated by men, only 16% of orthopaedic resident physicians and 6% of practicing orthopaedic surgeons are female, this was no small feat. Although there are many factors that made this historic team possible, it is clear that the earliest female pioneers of orthopaedic surgery were absolutely critical. This paper aims to discuss 5 pioneering women who not only created a path for the now thousands of female orthopaedic surgeons but also left a legacy of significant contributions to the practice of orthopaedics. These trailblazers are as follows: Dr. Marian Frauenthal Sloane, Dr. Ruth Jackson, Dr. Jacquelin Perry, Dr. Claudia Thomas, and Dr. Ericka Lawler.

OBJECTIVE:The purpose of this study was to describe our experience using superiorly applied low-profile locking plates for the operative fixation of displaced midshaft clavicle fractures (MCFs). STUDY DESIGN/METHODS:This was a retrospective analysis performed at an academic institution. RESULTS:Eighty-three patients who presented with displaced, shortened MCFs were treated operatively by a single surgeon at our institution over a 10-year period. All patients received a precontoured low-profile locking plate applied in the superior position. A displaced midshaft clavicle fracture was fixed operatively using a precountered low-profile 2.7/3.5 mm locking plate applied in the superior position. Data were analyzed to evaluate time to union, final shoulder range of motion, incidence of hardware removal, and rate of postoperative complications. The cohort was 66.2% male with an average age at initial injury of 36.5 ± 14.1 years. At a mean of 3.6 ± 1.9 months, 99% of patients had united their fracture. At an average of 7.37-month follow-up, mean range of motion was 174° forward elevation, 173° abduction, 82° external rotation, and internal rotation to T7. Using the short musculoskeletal functional assessment (SMFA), the mean functional outcome index score was 4.12, bothersome index was 1.94, activity index was 1.55, emotion index was 2.51, arm and hand index was 1.14, mobility index was 0.68, and total index was 1.56. Ninety-two percent of patients had retained their hardware. There was 1 incidence of each of the following complications: infection, nonunion, hardware failure, and deep vein thrombosis. CONCLUSION/CONCLUSIONS:Superior clavicle plating using precontoured low-profile locking plates is an acceptable treatment modality for displaced MCF. This method yields excellent results regarding time to union, shoulder range of motion, incidence of hardware removal, and the rate of postoperative complications. Patients considering operative fixation of displaced MCF should be counseled accordingly.

BACKGROUND:Acute blood loss anemia is a common complication of hip fractures. Due to this complication, the rate of allogenic blood transfusions remains high in this patient population. More recently, surgeons have utilized intraoperative tranexamic acid as a strategy to minimize blood loss. PURPOSE/OBJECTIVE:The purpose of this study was to identify risk factors and associated outcomes of blood transfusions in hip fracture patients. STUDY DESIGN/METHODS:Retrospective cohort study. METHODS:A trauma database from one academic medical center was queried for hip fracture patients (OTA/AO 31A or 31B). Demographic, clinical, quality, and cost data were obtained for each patient. A Score for Trauma Triage in Geriatric and Middle Aged (STTGMA), a validated risk predictive and matching tool, was calculated for each patient. Patients receiving blood transfusions during their hospitalization were identified. Multivariate logistic regression analysis identified independent risk factors for transfusion during admission. Patients receiving transfusions were matched to patients not receiving a transfusion based on STTGMA. Comparative analyses of matched cohorts were performed. RESULTS:In total, 1,344 hip fracture patients (29.8% male and 70.2% female) with mean age 81.04 ± 10.18 were identified. Four hundred ninety-nine (37.1%) patients received a transfusion during their admission. Risk factors for transfusion included higher STTGMA scores (P = .006), lower hemoglobin levels on admission (P < .001), anticoagulation or antiplatelet use on admission (P = .019), and fracture repair with a long cephalomedullary nail (P = .005). Trauma risk score-matched cohort outcomes show transfusions correlated with increased mortality, complications, readmission, and longer, more costly hospital stays. CONCLUSION/CONCLUSIONS:Surgeons should be cognizant of transfusion risk factors such as repair with long cephalomedullary nail and poorer matched outcomes correlated with patients receiving transfusions.

INTRODUCTION/BACKGROUND:To evaluate the impact of prolonged GLP-1 usage on mortality, readmission, incidence of in-hospital complications, and incidence of implant failure following hip fracture surgery across various BMI strata. METHODS:A prospective hip fracture registry (2014-2024) at a single institution was used to identify 58 obese patients on prolonged GLP-1 therapy at the time of injury. These patients (Group A) were matched by age, fracture pattern, and comorbidity burden to BMI-based control cohorts: normal (Group B), overweight (Group C), and obese (Group D). Postoperative complication rates, readmissions, and implant failures were compared. Major complications were defined as events needing further procedures, extended hospitalization, or causing significant functional impairment. Minor complications were those managed with minimal treatment. Statistical analysis included ANOVA, chi-square, and post hoc residual testing. Data were analyzed using IBM SPSS Statistics (Version 21.0, Chicago, IL). RESULTS: ≈ 17.33, p < 0.001): 22.41% in Group A, 55.17% in Group B, 51.72% in Group C, and 60.34% in Group D. Group D exhibited significantly higher 30-day (17.24%, p < 0.001) and 90-day (24.14%, p < 0.05) readmission rates. No significant differences were observed in major complications, hardware failure incidence, or 30-day or 1-year. CONCLUSIONS: ≥ 6 months of continuous GLP-1 receptor agonist therapy was associated with a reduction in 30-day and 90-day readmission rates and overall and minor in-hospital complications in obese patients undergoing hip fracture surgery. LEVEL OF EVIDENCE/METHODS:III.

OBJECTIVES/OBJECTIVE:Altered patellar height following patella fracture repair may affect clinical outcomes, but the significance remains unclear. The purpose of this study was to evaluate the impact of immediate and final follow-up Insall-Salvati Ratio (ISR) on postoperative outcomes following patella fracture fixation. METHODS:A retrospective review at a multi-site academic urban hospital system was conducted. All patients underwent patella open reduction and internal fixation (ORIF) for displaced patella fracture (OTA 34) from 2012 to 2024. Final intraoperative and final follow-up radiographs were assessed by Insall-Salvati ratios (ISR). Patients were categorized into groups based on intraoperative ISR measurements: normal ISR, defined as .8-1.2 and abnormal ISR, outside of the 0.8-1.2 range. Follow-up radiographs were also assessed for abnormal ISR. Knee range of motion (ROM), post-operative complications, and fracture union were collected. Statistical analysis included Pearson Chi-squared tests, independent t-tests, and ANOVA tests. RESULTS:Of 191 patients, 163 (85.3%) had normal ISR and 28 (14.7%) had abnormal ISR postoperatively. Abnormal ISR was associated with higher complication rates (14.3% vs. 4.3%, p = 0.037), hardware failure (10.7% vs. 1.2%, p = 0.004), reduced knee range-of-motion at three months (105.13 ± 21.38 vs. 117.22 ± 13.75, p < .001) and six months (119.25 ± 14.26 vs. 127.37 ± 13.27, p = .020). Among patients with initially normal ISR, 12.3% developed patella baja, which was associated with higher rates of hardware removal (20% vs. 3.1%, p = 0.004) and infection (10% vs. 0.8%, p = 0.015) when compared to patients maintaining a normal ISR. CONCLUSIONS:Abnormal intraoperative Insall-Salvati ratio following patella fracture repair was associated with poorer knee ROM and increased complication rate. Progressive development of patella baja during fracture healing was associated with hardware removal and fracture related infection. Attention to intraoperative ISR optimization may improve outcomes.

Most surgically repaired proximal femoral fractures heal uneventfully, however a small percentage of surgical interventions lead to failures. Salvage of failed treatment is challenging and dependent on the type and location of the complication. Potential complications of intracapsular hip fractures and their treatment include fixation failure, nonunion, and osteonecrosis of the femoral head. Factors guiding the choice of salvage option include patient age and quality of remaining bone. This article aims to present several potential complications and corresponding potential solutions using supporting literature, when available. This narrative review focuses on salvage treatment options of failed fixation of femoral neck fractures. Total hip arthroplasty is always the last resort salvage option.

PURPOSE/OBJECTIVE:The purpose of this study was to compare fracture nonunion rates in tibial shaft fractures fixed with intramedullary nails using fixed angle locking screws (FALS) that thread into the intramedullary nail versus standard locking screws in a cohort of tibial diaphyseal fractures. Secondarily, this study evaluated whether FALS location was associated with nonunion risk in tibial diaphyseal fractures. METHODS:A retrospective review of surgically treated OTA 42 A-C tibial shaft fractures from 2014 to 2024 at a single academic institution was performed. Inclusion criteria were age > 18, isolated OTA 42 A-C tibia fracture, intramedullary nail fixation, and minimum 6-month follow-up. Patients treated with a FALS were matched to those without a FALS with a 1:1 propensity match based on OTA fracture classification and open fracture status. The Radiographic Union Score for Tibia (RUST) was used to determine healing. Statistical comparisons were performed using Pearson Chi-squared tests, independent t-tests, Mann Whitney-U tests, and multivariate logistic regression as appropriate. RESULTS:78 patients were included (39 in each cohort), with the FALS group being older and having higher age-unadjusted Charlson Comorbidity Indices (CCI). The FALS and CLS groups had comparable rates of open fractures and similar proportions of OTA/AO fractures. FALS configuration per patient was: 16 only distal, 13 only proximal, and 10 both proximal and distal. There were no differences in nonunion rates (25.6% vs. 15.4%, p = 0.262) and healed-by times (6.15 ± 2.95 [months] vs. 6.38 ± 2.73, p = 759), complication rate, or 30/90-day readmission rates (p < 0.05). Multivariate analysis demonstrated that the use of single-end FALS (used only proximally or distally) was independently associated with higher odds of nonunion compared to CLS and FALS used both proximally and distally (OR = 6.027, p = 0.025). CONCLUSION/CONCLUSIONS:The use of single-end fixed angle locking screws in only the distal or proximal segment in intramedullary nails for the treatment of OTA 42 A-C tibial diaphyseal fractures is associated with higher odds of fracture nonunion. Larger, prospective studies evaluating FALS configuration for intramedullary nail fixation of tibia shaft fractures are warranted.

BACKGROUND/UNASSIGNED:This study compares outcomes and complications of patients with Bado II Monteggia fracture-dislocations that required radial head fixation or replacement based upon approach to the radial head. METHODS/UNASSIGNED:A retrospective review was performed of 159 consecutive patients with proximal ulna fractures and a radial head dislocation or fracture (Monteggia Variant). Injuries were classified by Bado type. Forty-one patients with Bado II Monteggia injuries treated with either a radial head replacement or fixation with complete follow up were included. Demographics, injury information, surgical details, and follow up information including elbow range of motion (ROM) and complications were collected. A trans-osseous posterior (TOP) approach working through the ulna fracture to address the radial head first was used in 19 patients, while 22 patients had their radial head treated via a separate lateral (Kocher) interval after ulnar fixation. Ulnar plate fixation was performed for all patients. Comparisons were made using independent t-tests. RESULTS/UNASSIGNED:Forty-one Monteggia lesions treated through TOP (19, 46 %) or Kocher (22, 64 %) approaches underwent a radial head replacement (33, 80.5 %) or fracture repair (8, 19.5 %) with a mean final follow-up of 15.3 months. At all post-operative visits, groups displayed similar rates of functional elbow ROM. At latest follow-up rates of patient-reported pain, ultimate elbow ROM, time to radiographic healing were equivalent. No significant differences were observed in ulna non-union, joint malalignment, post-operative nerve injury, post-operative infection, heterotopic ossification, incidence of hardware failure, patient-reported pain, and rate of removal of symptomatic hardware. Sub-analysis of radial head replacement versus fixation revealed equivalent percentage of patients with full ROM at each post-operative time point. CONCLUSION/UNASSIGNED:For Bado II Monteggia fracture-dislocations, the surgical approach to the radial head-TOP versus Kocher-does not influence ultimate patient outcomes or complication rates. Radial head replacement and fixation provide comparable results. LEVEL OF EVIDENCE/UNASSIGNED:III.

INTRODUCTION/BACKGROUND:Tibial plateau fractures are some of the most commonly treated injuries around the knee and loss of range of motion has a significant effect on post-operative outcomes, very few studies have demonstrated the impact of flexion contractures. The purpose of this study was to determine the effect that development of a knee flexion contracture has on outcomes following operative repair of tibial plateau fractures. METHODS:Patients operatively treated for tibial plateau fractures (Schatzker II, IV, V, and VI) between 2005-2024 at a multi-center academic urban hospital system were included in this retrospective comparative study. Patients were grouped into 3 cohorts: 1. Full extension (FE), 2. 5-10 degrees of flexion contracture (Mild, ME) and 3. Greater than 10 degrees of flexion (Severe, SE) contracture at 6 months post-operatively. Patients with contracture were matched to patients who regained full extension based on age and Schatzker classification. Statistical analysis was used to evaluate outcomes including patient reported pain levels, Short Musculoskeletal Function Assessment (SMFA) scores, complication rates and reoperation rates. RESULTS:The cohort consisted of 3 groups of 30 patients (14 Schatzker II, 5 Schatzker IV, 3 Schatzker V, and 8 Schatzker VI). The average knee flexion contracture for the mild cohort was 5 degrees and the average knee flexion contracture for the severe cohort was 12.7 degrees. Patients who experienced flexion contracture had poorer SMFA scores at 6 months, and those in the severe cohort had the poorest SMFA scores (112.6) when compared to those with full extension at 6 months (77.7) (p<0.001). Flexion contractures were associated with higher rates of fracture related infection (FRI) (p =0.002). Patients with flexion contracture also had a higher rate of subsequent re-operation, with 36.7% of the ME undergoing re-operation and 40% of SE undergoing re-operation. CONCLUSIONS:Patients who developed a flexion contracture following repair of a tibial plateau fracture experienced worse outcomes, higher rates of complications, increased pain, and poorer function at long term follow up compared to those who achieved full knee extension.
