Pediatric Type I Open Both Bone Forearm Fractures: Predicting Failure of Nonoperative Management.

BACKGROUND: In recent years, nonoperative treatment of pediatric type I open both bone forearm fractures (OBBFFs) with bedside irrigation, antibiotics, closed reduction, and casting has yielded low infection rates. However, risk factors for failure of type I OBBFF closed reduction have not been well described. Our purpose was to describe management of patients with type I OBBFFs at our institution and determine what factors are associated with failure of closed reduction in this population. METHODS: This was a review of patients between 5 and 15 years of age who received initial nonoperative management for type I OBBFFs at one institution between 2015 and 2021. Primary outcome was success or failure of nonoperative management (defined as progression to surgical management). Secondary outcomes included infections, compartment syndromes, and neuropraxias. Other variables of interest were demographic information, prereduction and postreduction translation and angulation of the radius and ulna, cast index, and antibiotic administration. RESULTS: Sixty-one patients (67.7% male) with 62 type I OBBFFs were included in this study. Following initial nonoperative management, 55 injuries (88.7%) were successfully treated in casts, while the remaining 7 (11.3%) required surgical intervention following loss of acceptable reduction in cast. Median cast index (0.84, IQR 0.8 to 0.9 vs. 0.75, IQR 0.7-0.8, P =0.020) and postreduction radius translation on anteroposterior films (32.0%, IQR 17.0% to 40.0% vs. 5.0%, IQR 0.0% to 26.0%, P =0.020) were higher among those who failed nonoperative management. Multivariable logistic regression models identified increased odds of failure for every SD (0.7) increase in cast index (OR 3.78, P =0.023, 95% CI: 1.4-14.3) and 25% increase in postreduction radius translation on anteroposterior films (OR 7.39, P =0.044, 95% CI 1.2-70.4). No infections or compartment syndromes and 2 transient ulnar neuropraxias occurred. CONCLUSIONS: Closed reduction of type I OBBFFs was successful in 88.7% of cases. There were no infections after nonoperative management. Increases in cast index of 0.7 and postreduction radius translation on anteroposterior radiographs of 25% were associated with increased likelihood of failure, thus requiring surgery; age was not. LEVEL OF EVIDENCE: Level IV-retrospective comparative study.

Systematic Review of Gender and Sex Terminology Use in Arthroplasty Research: There Is Room for Improvement.

BACKGROUND: There is increasing appreciation of the distinction between gender and sex as well as the importance of accurately reporting these constructs. Given recent attention regarding transgender and gender nonconforming (TGNC) and intersex identities, it is more necessary than ever to understand how to describe these identities in research. This study sought to investigate the use of gender- and sex-based terminology in arthroplasty research. METHODS: The 5 leading orthopaedic journals publishing arthroplasty research were reviewed to identify the first twenty primary clinical research articles on an arthroplasty topic published after January 1, 2022. Use of gender- or sex-based terminology, whether use was discriminate, and whether stratification or adjustment based on gender or sex was performed, were recorded. RESULTS: There were 98 of 100 articles that measured a construct of gender or sex. Of these, 15 articles used gender-based terminology, 45 used sex-based terminology, and 38 used a combination of gender- and sex-based terminology. Of the 38 articles using a combination of terminology, none did so discriminately. All articles presented gender and sex as binary variables, and 2 attempted to explicitly define how gender or sex were defined. Of the 98 articles, 31 used these variables for statistical adjustments, though only 6 reported stratified results. CONCLUSIONS: Arthroplasty articles infrequently describe how gender or sex was measured, and frequently use this terminology interchangeably. Additionally, these articles rarely offer more than 2 options for capturing variation in sex and gender. Future research should be more precise in the treatment of these variables to improve the quality of results and ensure findings are patient-centered and inclusive.

Ulnar Epiphysiodesis: Success of the Index Procedure.

INTRODUCTION: Premature radial physeal closure is a relatively rare occurrence in children. When isolated growth arrest of the radius with continued ulnar growth occurs, the resulting ulnar positive deformity leads to altered wrist mechanics and pain. Timely epiphysiodesis of the distal ulna with and without ulnar shortening osteotomy can address these issues, but continued ulnar overgrowth is a possible complication. We seek to evaluate the success rate of the primary epiphysiodesis of the ulna and associated clinical outcomes. METHODS: A chart review was conducted at 2 children's hospitals from 2008 to 2019. Patients between the ages of 6 and 18 years old, with premature distal radius physeal closure, with or without positive ulnar variance, and >2 months follow-up were included. We evaluated the following characteristics for each patient: demographics, initial cause of premature radial physeal closure, ulnar variance, additional procedures performed during epiphysiodesis, preoperative and postoperative pain, range of motion, instability. Summary statistics were conducted and expressed as proportions, medians and means. A paired t test evaluated change in ulnar variance for those who had an ulnar shortening osteotomy performed. RESULTS: Thirty-one wrists among 30 patients were identified, and the median age at the time of surgery was 12.2 years (interquartile range: 3.4). Ulnar shortening osteotomies were performed in 53.1% of cases and distal radius osteotomy in 15.6%. Bone graft was utilized in 25.8% of the epiphysiodesis procedures. There were 2 failures of primary epiphysiodesis indicating an index success rate of 93.7%. The average ulnar variance correction was 3.1 mm (95% confidence interval: 1.9, 4.4). The mean physeal time to closure was 134 days. Preoperative symptoms were resolved for 90.6% cases at final follow-up. CONCLUSION: Ulnar epiphysiodesis successfully terminates ulnar physeal growth in 93.7% of cases. Preoperative symptoms were completely resolved with a median physeal closure of just over 4 months. Ulnar variance was corrected on average by 4.1 mm when a radial or ulnar shortening osteotomy was performed at the time of epiphysiodesis. LEVEL OF EVIDENCE: Level IV-case series.

Bone Health in the Transgender Population.

¼ Transgender women are more susceptible to low bone mineral density (BMD) before initiating gender-affirming hormone therapy (GAHT), and while bone density initially improves with GAHT, it gradually declines while still remaining above baseline. Transgender women older than 50 years have a comparable fracture risk as age-matched cisgender women. Transgender men typically have normal or increased BMD before initiating and while receiving GAHT and are not at increased risk of fractures.¼ Transgender youth who receive puberty-blocking medications experience either no change or a slight decrease in BMD that returns to baseline after initiating GAHT.¼ It is important to abide by the International Society for Clinical Densitometry guidelines whenever ordering, performing, or reading a BMD scan for a gender-diverse patient.¼ There are no specific guidelines concerning vitamin D and calcium supplementation or the use of bisphosphonates in the transgender population, so the current recommendation is to abide by the guidelines for cisgender individuals.

Treatment of Chronic Ankle Instability in the Military Population: A Systematic Review.

BACKGROUND: The high incidence of ankle sprain within the military sets the stage for prevalent chronic ankle instability. The purpose of this review was to compare and evaluate chronic ankle instability treatment strategies in the military population. METHODS: Electronic databases were systematically searched in accordance with the Preferred Reporting Items for Systematic Reviews guidelines for English-language, human studies with a military patient population that had been diagnosed with and treated for chronic ankle instability. Exclusion criteria were animal, cadaver, and review studies and case reports. RESULTS: Eight studies met the inclusion criteria, representing 695 military service members-625 males (89.9%) and 70 females (10.1%)-and 4 treatment strategies: Broström-related procedures, modified Watson-Jones procedure, Colville's technique, and anatomic lateral ligament reconstruction using semitendinosus tendon allograft. The percentage of satisfactory outcomes was 100% for Colville's technique, and ranged from 73.2% to 94.7% for Broström-related procedures and 72% to 80% for the modified Watson-Jones procedure. Mean American Orthopaedic Foot and Ankle Society scores, anterior drawer displacement, talar tilt, and visual analogue scale scores were also reported. CONCLUSION: This review demonstrates that the Bröstrom procedure has consistently satisfactory outcomes within the military population, and Colville's technique is another promising option for this patient population but would require additional studies to support this claim. LEVELS OF EVIDENCE: Level IV.

Epidemiology of Ankle Sprain in the Active-Duty Military Population.

¼: Ankle sprain is one of the most prevalent injuries within the military population, resulting in health-care costs, time away from active duty, and negative impacts on overall readiness. ¼: Female service members appear to be more likely to sustain ankle sprains than male service members. ¼: There is a need for additional research on prevention methods and rehabilitation programs for ankle sprains in the military population because the rate of ankle sprain in this population exceeds that in populations with less physically demanding lifestyles. Consequently, low-cost prevention strategies could yield substantial benefits.

Sex-specific differences in outcomes after anterior shoulder surgical stabilization: a meta-analysis and systematic review of literature.

BACKGROUND: Anterior shoulder instability frequently occurs in young, physically active individuals and may be treated with surgical stabilization. Previous studies have shown that males more often require surgical management for anterior shoulder instability and may have a higher frequency of recurrent instability episodes after surgical management, but females have been found to have increased incidence of apprehension after surgical stabilization. The purpose of this study is to review the literature and assess anterior shoulder surgical stabilization postoperative outcomes between males and females to identify and describe sex-based differences. METHODS: A systematic search of electronic databases was conducted to identify level I-IV clinical studies on anterior shoulder instability published between 1960 and August 2020. We included studies that evaluated sex-specific outcomes in patients who underwent anterior shoulder instability procedures. A meta-analysis of the data was performed to analyze sex-specific outcomes. RESULTS: Thirty studies (2.1%) met inclusion criteria, representing 9829 patients. Of the studies that reported the number of male and female patients, 74% were male and 26% were female. Twenty-six studies used Bankart repair alone, two used open Latarjet procedure alone, and two had a Bankart repair group and Latarjet procedure group. Instability recurrence, return to sport, and apprehension were included in the meta-analysis. Our meta-analysis demonstrated a significantly higher rate of instability recurrence for males than for females who underwent arthroscopic Bankart repair (risk ratio [RR] = 1.25; 95% confidence interval [CI] = 1.03, 1.52; P = .0239). We did not identify a significant difference between males and females in rates of apprehension (RR = 0.68; 95% CI = 0.37, 1.27; P = .2300) or return to sport (RR = 0.98; 95% CI = 0.81, 1.18; I2 = 0%; P = .8110) for arthroscopic Bankart repair or open Latarjet procedure. CONCLUSION: For patients who underwent arthroscopic Bankart repair for anterior shoulder stabilization, recurrent rates of instability were significantly higher for males than for females. When open Bankart and Latarjet procedures were included, there was no difference. No difference was seen between males and females after arthroscopic Bankart repair or open Latarjet procedures with regard to return to sport or apprehension.

Sex-Specific Differences Following Lateral Ankle Ligament Repair.

BACKGROUND: Chronic ankle instability is a common condition that can be treated with lateral ankle ligament repair. These procedures have a reported success rate greater than 85% in the literature, but little has been reported about the differences in postoperative outcomes between males and females. The purpose of this study was to evaluate sex-specific outcomes following lateral ankle ligament repair. METHODS: In this systematic review and meta-analysis, we used Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria to search for articles on electronic databases and included studies in which study participants underwent primary lateral ligament repair and sex-specific outcomes were evaluated. Functional postoperative outcomes for males and females were recorded and statistically analyzed. RESULTS: Out of 2768 studies, 7 (0.25%) met inclusion criteria and were analyzed in this review. These studies included 618 patients (402 males [65%] and 216 females [35%]) who underwent primary lateral ligament repair for ankle instability. Karlsson score (P = .1582) and American Orthopaedic Foot & Ankle Society (AOFAS) score (P = .1586) analyses found no statistically significant difference between males and females. Postoperative success rate-defined as a "good" or "excellent" Karlsson score (>81)-was not found to be significantly different between males and females (P = .9374). CONCLUSION: There was no difference in postoperative mean Karlsson scores, AOFAS scores, or success rates between males and females who underwent primary lateral ankle ligament repair. LEVEL OF EVIDENCE: Level IV, therapeutic.
