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.

OBJECTIVES/OBJECTIVE:Increased mortality following geriatric hip fractures is well reported. However, population-level analysis of mortality trends over time are not common. This study aimed to evaluate the 3- and 12-month mortality after geriatric hip fractures from 2010 to 2019. METHODS:The New York Statewide Planning and Research Cooperative System database from 2010 to 2020 was retrospectively queried for patients aged >65 years with a femoral neck or intertrochanteric hip fracture. Kaplan-Meier survival analysis was used to calculate mortality rates for each year. Cox proportional hazard multivariable regression controlling for sex, age, race, obesity, smoking, and Elixhauser comorbidity index was used to compare mortality hazard ratios for each year. Secondary outcomes included length of stay, discharge disposition, and 3-month readmission and emergency department visits. RESULTS:From 2010 to 2019, 142,540 patients aged ≥65 years had a diagnosis of femoral neck fracture (62%) or intertrochanteric hip fracture (38%). The mean age was 83.29 years (SD 8.22). The mean Elixhauser comorbidity index was 7.35 (SD 7.60). Kaplan-Meier survival analysis revealed that for the complete cohort 3-month mortality rate was 9.82% (95% confidence interval 9.65% to 9.98%) and 12-month mortality rate was 16.06% (95% confidence interval 15.84% to 16.27%). The 3-month mortality rate went from 10.8% in 2010 to 8.6% in 2019 and the 12-month mortality rate went from 17.7% in 2010 to 14.8% in 2018 before rising to 16.9% in 2019. Cox multivariate proportional hazard regression demonstrated statistically significant decreased hazard ratio from 2012 to 2019 compared with reference hazard in 2010 (all P < 0.05). Reductions were also observed for length of stay (7.8 to 6.4 days, P < 0.001), 3-month readmissions rate (34% to 22%, P < 0.001), and 3-month emergency department visit rate (45% to 34%, P < 0.001). CONCLUSION/CONCLUSIONS:Mortality after geriatric hip fractures has demonstrated a reduction in the past decade with 3-month mortality continuously decreasing from 2010 to 2019 and 12-month mortality decreasing from 2010 to 2018 before increasing in 2019.

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:To develop a stratification tool to identify hip fracture patients at risk for second contralateral hip fracture and mortality within 5 years of an index fracture, and to assess the cost-effectiveness of prophylactic fixation in high-risk/low-mortality patients. METHODS:Design: Retrospective prognostic cohort study. SETTING/METHODS:Single academic system with 2 Level 1 Trauma Centers, 1 orthopedic specialty hospital, and 1 tertiary care hospital. PATIENT SELECTION CRITERIA/UNASSIGNED:Patients who were 60 years or older with OTA 31A/B hip fractures from low-energy mechanisms between 11/1/2014 and 11/31/2023 with ≥5 years follow-up or until death were included. OUTCOME MEASURES AND COMPARISONS/UNASSIGNED:The study included four phases: (1) identifying factors associated with second hip fracture within 5 years; (2) using multivariate logistic regression to generate models predicting 5-year second hip fracture (vs. FRAX) and mortality risk; (3) creating a "risk matrix" to identify candidates for prophylactic fixation using Youden's Index which determined cutoff points encompassing the maximum sensitivity and specificity for each risk equation and were used to define a value-based target group; (4) cost analysis comparing standard vs. prophylactic care in high-risk/low-mortality patients. RESULTS:Of 426 patients (mean age 80.25 years, 73.4% female), 78 sustained second hip fractures (mean interval: 594 days). Predictors included higher FRAX score (p=0.004), dementia (p<.001), ICU stay (p=0.014), discharge to subacute care (p<.001), and 90-day readmission (p=0.011). Logistic regression predicted 5-year second fracture risk (AUC 0.742 vs. FRAX 0.617, p=0.012) and 5-year mortality (AUC 0.723). The risk matrix used cutoff points of 18.2% (mortality) and 38.2% (second fracture) to define a value-based target group (n=26; 13 experienced second fracture). Cost analysis showed prophylactic fixation of all 26 patients ($781,508) would save $353,067 compared to treating the 13 who fractured again ($1,134,575). CONCLUSIONS:A novel matrix was developed that accurately predicted 5-year second hip fracture and mortality risk. Prophylactic fixation in low-mortality, high-risk patients may reduce costs and prevent future fractures.

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.

OBJECTIVE:To determine if the occurrence of short-term post-operative altered mental status (AMS) was lower in geriatric patients undergoing operative repair of hip fractures with Monitored Anesthesia Care and Soft-Tissue Infiltration with Local Anesthesia (MAC-STILA) when compared with general anesthesia (GA). DESIGN/METHODS:Retrospective cohort study. SETTING/METHODS:Two U.S. hospitals within a single academic medical center. PATIENT SELECTION CRITERIA/UNASSIGNED:Geriatric patients with hip fractures (AO/OTA 31A and 31B) undergoing operative repair were identified. Propensity matching was performed in a 1:2 ratio to minimize selection bias (age, sex, BMI, ASA class, fracture pattern, fixation construct, pre-injury ambulatory status, and assistive device use). OUTCOME MEASURES/METHODS:Patients who underwent surgical fixation with MAC-STILA were compared with GA. Primary outcome was post-operative AMS, defined as missing ≥1 items on the alert and oriented assessment (person, place, and time) at any point from post-operative days 0-3. RESULTS:After matching, 228 patients (76 MAC-STILA: 152 GA) were included in the analysis. The average age of patients in both groups was 83 years. In the MAC-STILA group, 62% were female and 33% had baseline dementia while in the GA group 66% were female and 29% had baseline dementia. Treating patients with MAC-STILA was associated with 72% lower odds of having AMS compared with GA, controlling for baseline comorbidity and dementia (OR: 0.28. 95% CI: 0.09-0.075, p=0.016). Among patients with baseline dementia, the rate of AMS was lower in patients treated with MAC-STILA compared with GA (64.0% vs 95.3%, p = 0.001). CONCLUSION/CONCLUSIONS:Monitored Anesthesia Care and Soft-Tissue Infiltration with Local Anesthesia (MAC-STILA) was associated with lower odds of short-term postoperative altered mental status (AMS) compared to general anesthesia (GA) in hip fracture patients undergoing operative repair. Given the high rate of post-operative AMS and complications associated with geriatric hip fracture patient, MAC-STILA should be considered for use in patients with increased risk of post-operative AMS, particularly in the setting of preoperative dementia.

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.

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.

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.

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.
