OBJECTIVE: To evaluate the effect of joint preparation and patient factors on outcomes and complications in patients treated acutely with hindfoot fusion nails for ankle and pilon fractures. METHODS: Design: Retrospective chart review. Setting: Thirteen US trauma centers and 2 UK trauma centers. Patient Selection Criteria: Ankle and pilon fractures (AO-OTA types A-C) from 2010 to 2020 acutely treated definitively with hindfoot fusion nail were reviewed. Patients at least 18 years old and with minimum 6 months follow-up or earlier diagnosis of complication were included. Exclusion criteria included nonambulatory at baseline, prior internal fixation that failed and underwent revision, and prior tibiotalar or subtalar arthrodesis. Outcome Measurements and Comparisons: The primary outcome was final postoperative ambulatory status. Secondary outcomes were infectious and fracture-related complications. RESULTS: One hundred forty-nine patients (75 men; 74 women; age 20–99; median 63 years) were treated for ankle (104) or pilon (45; 8A, 13B, 24C) fractures. Eighty-five patients (44%) had open fractures and 55 (37%) had diabetes. Thirty-six patients (24%) had joint preparation at the time of surgery. Forty-five (30%) were made weight bearing as tolerated postoperatively; the median time to mobilize was 1.5 days (0–210) and to full weight bearing was 35 days (0–1462). Fifty-seven patients (85%) returned to their preinjury ambulatory status, which was not affected by joint preparation (50% vs. 59%, P = 0.327). Joint preparation led to higher articular fusion rates (94% vs. 24%; P = 0.001) and fewer hardware removals (19% vs. 42%, P = 0.013), but trended toward a higher fracture nonunion rate (19% vs. 8%, P = 0.053). Forty-five patients (30%) had infectious complications, 60 (40%) had a fracture-related complication, and 67 (45%) had additional procedures. Open fractures did not lead to any differences in superficial or deep infection. Insulin-dependent diabetes was associated with higher rates of infectious complications (31% vs. 15%, P = 0.028) and amputation (17% vs. 4%, P = 0.029). CONCLUSIONS: Hindfoot fusion nails for acute ankle and pilon injuries had high complication rates. More complications occurred in patients with insulin-dependent diabetes. While 95% regained ambulation, only 57% returned to preoperative status. Joint preparation led to higher rates of articular fusion (94% vs. 24%, P < 0.001) but not fracture union (81% vs. 66%, P = 0.106). LEVEL OF EVIDENCE: Prognostic Level III.

Background: Tibiotalar arthrodesis (TTA) is a common operation for end-stage ankle arthritis. Elevated body mass index (BMI) is believed to contribute to complications following TTA. Previous studies involved national registries or small, underpowered cohorts. This study aimed to determine the effects of elevated BMI on nonunion and complication rates following TTA with a large cohort from a single academic institution. Methods: A retrospective study identified 514 patients (527 ankles) who underwent primary TTA from 2005-2017. Mean age was 60 years. Patients were stratified by BMI according to the World Health Organization classification. A reference group of 203 patients (208 ankles) included normal weight or mildly overweight patients (BMI 18.5 to <30). Ankle radiographs were evaluated to determine union or nonunion. Other outcomes included revision TTA, reoperations, subsequent adjacent joint arthrodesis, infection, and readmission. Data were analyzed using Pearson χ 2 and odds ratios for categorical variables. Analysis of variance and Kaplan-Meier estimation assessed continuous variables and time-to-event outcomes, respectively. Mean follow-up was 34.3 months. Results: Obesity class III patients had elevated risk of complications compared with normal weight patients including nonunion (odds ratio [OR] 3.96, P = .002), revision (OR 3.69, P = .03), superficial infection (OR 9.36, P = .002), and readmission (OR 10.90, P = .01). Superficial infection rates were elevated in class I (OR 6.36, P = .007) and readmissions in class II (OR 9.98, P = .01). No differences were found in reoperation ( P = .448), symptomatic implant removal ( P = .805), adjacent joint arthrodesis ( P = .353), or deep infection ( P = .507) rates. Discussion: In this retrospective review after TTA, increased rates of nonunion, revision, superficial infection, and readmission were found in obesity class III patients, compared with the reference group of normal weight or mildly overweight patients. Superficial infection rates were likewise relatively elevated in class I and readmission rates in class II patients.

OBJECTIVES: To evaluate tranexamic acid (TXA) when administered immediately on hospital presentation in patients with extracapsular peritrochanteric hip fractures to determine its effect on (1) transfusion rates, (2) estimated blood loss, and (3) complications. METHODS: Design: Prospective, double-blinded, randomized clinical trial. Setting: Single-center, Level 1 trauma center. Patient Selection Criteria: All patients with isolated OTA/AO 31-A fracture patterns from 2018 to 2022 were eligible for inclusion. Study drug was administered in the emergency department at the time of presentation—1-g bolus over 10 minutes followed by a 1-g infusion over 8 hours. Outcome Measures and Comparisons: The primary outcome was the rate of red blood cell transfusion hospital days 1–4. Secondary outcomes included estimated blood loss and complications including venous thromboembolic events, stroke, myocardial infarction, all-cause 90-day readmissions, and all-cause mortality. RESULTS: One hundred twenty-eight patients were included—64 patients were randomized to intravenous TXA and 64 patients to intravenous normal saline (ie, placebo). There was no difference in the rate of red blood cell transfusion between treatment arms between hospital days 1–4 (27% in the TXA arm vs. 31% in the placebo arm, P = 0.65). Patients randomized to placebo who required transfusion received a mean of 2.30 units compared with 1.94 units in the TXA cohort (P = 0.55). There was no difference in the estimated blood loss between hospital days 1–4. There was no difference in the incidence of postoperative complications including venous thromboembolic events, stroke, myocardial infarction, 90-day readmission, or death. CONCLUSIONS: The results of this study do not support the use of preoperative TXA for reducing blood loss for geriatric patients with extracapsular hip fractures.

Background: The increased focus on patient satisfaction has led to growth in the use of physician rating websites. Purpose: To analyze the factors associated with online 5-star patient reviews for orthopaedic sports medicine surgeons. Study Design: Cross-sectional study. Methods: A total of 70 orthopaedic sports medicine surgeons were randomly selected from the AOSSM website. A search was performed for these surgeons on Yelp.com. All reviews other than 5 stars (of a possible 5 stars) were excluded from the study. Each review was categorized as referring to a surgical or nonsurgical aspect of care, and each comment within the review was categorized as being clinically or nonclinically related. Comments were further subcategorized by specific features such as bedside manner, clinical outcomes, and patient education. Categorical variables were analyzed using the chi-square test. Results: Overall, 400 five-star reviews were included in the study, comprising 1225 total positive comments. Of the 400 five-star reviews, 200 (50%) were from surgically treated patients, and 200 (50%) were from nonsurgically treated patients. Of the 1225 positive comments, 505 (41%) were clinically related, and 720 (59%) were nonclinical. The most common positive clinical comments were for clear treatment plans (191 reviews [48%]), good outcomes (173 reviews [43%]), and providing alternative treatment plans (55 reviews [14%]). The most common positive nonclinical comments were for good physician bedside manner (287 reviews [72%]), friendly/professional staff (194 reviews [49%]), and ease of scheduling (68 reviews [17%]). Conclusion: The majority of 5-star patient reviews left positive comments regarding nonclinical aspects of care such as physician bedside manner and friendly staff. The most common positive comments regarding clinical aspects concerned good outcomes and clear treatment plans. The overall most common positive comment, in both surgically and nonsurgically treated patients, referred to good bedside manner.

Objectives: To investigate the correlation between a screw's radiographic relationship to the piriformis fossa with position on CT in the clinical setting. Methods: Intraoperative fluoroscopic images of patients treated with cannulated screw fixation of a femoral neck fracture, who also had a postoperative CT scan, were retrospectively evaluated by 4 fellowship-trained orthopaedic trauma surgeons. The posterosuperior screw on the AP fluoroscopic view was determined to be above the piriformis fossa (APF) or below the piriformis fossa (BPF). Using CT scan to determine IOI placement, the ability to predict IOI position based on fluoroscopic imaging was evaluated by calculating accuracy, sensitivity, specificity, and interobserver reliability. Results: 73 patients met inclusion criteria. The incidence of IOI screw placement was 59% on CT evaluation. The use of the PF landmark accurately predicted CT findings in 89% of patients. A screw placed APF was 90% sensitive and 88% specific in predicting cortical breach, with near-perfect interobserver agreement (κ = 0.81). Conclusion: The use of the PF radiographic landmark is highly sensitive and specific in predicting the placement of an IOI posterosuperior femoral neck screw. Level of Evidence: Diagnostic Level II.

Purpose To use the National Collegiate Athletic Association Injury Surveillance Program (NCAA‐ISP) from the 2009‐2010 through the 2014‐2015 seasons to report lumbar spine injury rates, characteristics, and time lost from sport in soccer players. Methods Characteristics of lumbar spine injuries by season, competition/practice, and time lost from sport were determined using the NCAA‐ISP database. Rates of injury were calculated as the number of injuries divided by the number of athlete exposures (AEs). AEs are any athlete participation in a competition or practice. Incidence rate ratios (IRRs) were calculated to compare rates between event types and time of season. Injury proportion ratios (IPRs) were used to evaluate differences in injury rates between men and women. Results The NCAA‐ISP estimated 4,464 LSIs over 5 years. The rate of LSI in men was 2.1/10,000 AEs and 3.0/10,000 AEs in women. Women were 1.43 times more likely to suffer an LSI compared to men. Women were 2.15 times as likely to suffer an LSI in competition compared to in practice while men were 1.10 times as likely. Women were 2.15 times as likely to be injured in the preseason compared to the regular season, while men were 3.76 times as likely. Non‐contact injuries were the most common cause of lumbar spine injuries (LSIs) in men (35%); however, contact injuries were more common in women (33%). Most athletes both male (57%) and female (59%) returned to play within 24 hours. Conclusion This study provides information on the characteristics of LSIs in NCAA soccer. The overall injury rate to the lumbar spine is relatively low. Injury rates are highest in the preseason and in competition. Women suffer from more recurrent LSI’s than men, and men acquired more injuries through non‐contact mechanisms. More than one‐half of athletes returned to sport within 24 hours.

Background: Although lower back injuries (LBIs) are common among National Collegiate Athletic Association (NCAA) female volleyball athletes, their incidence and etiology has not been well-defined. Purpose: To describe the epidemiology of LBIs in collegiate female volleyball athletes over a 5-year period from the academic years 2009 to 2010 and 2013 to 2014. Study Design: Descriptive epidemiology study. Methods: The incidence and characteristics of spine injuries were identified utilizing the NCAA Injury Surveillance Program database. Rates of injury were calculated as the number of injuries by the total number of athlete-exposures (AEs). AEs were defined as any student participation in any single NCAA-sanctioned practice or competition. The injury rate was computed as the number of injuries per the total number of AEs and reported as a ration of injuries per 10,000 exposures. The ratio was then reported as overall number as well as stratified for event, time of season, and athletic NCAA division. Incidence rate ratios were then calculated to compare rates between event type. Results with 95% CIs that did not include 1.0 were considered statistically significant. Results: An estimated 3384 LBIs occurred in NCAA female volleyball players during this 5-year time frame. These LBIs occurred at a rate of 4.89 injuries per 10,000 AEs. LBIs were 2.76 times more likely in preseason when compared with regular season. More injuries occurred in practice (85%) when compared with competition (15%). The outside hitter and middle blocker were the most commonly position to sustain an LBI. Almost 70% of injuries were new injuries, and another 29% were recurrent injuries. The most common mechanism of injury was equally split between contact (50.4%) and overuse (45.5%) injuries, whereas the remaining mechanisms of injury were secondary for unknown reasons (4.14%). Most players returned to play within 24 hours (72.3%) followed by 1 to 6 days (16.4%), and finally 7 to 12 days (11.3%). No patient required surgical intervention. Conclusion: The rate of LBIs was high (4.89/10,000 AEs) and injuries commonly recurred (29.2%). Most injuries were new, with most athletes returning to play with 24 hours.
