Orthopaedic Sports Medicine Randomized Controlled Trials Infrequently Report on the Social Determinants of Health Factors of Their Patient Cohorts.

PURPOSE: To describe the prevalence of randomized controlled trials (RCTs) in orthopaedic sports medicine-related journals reporting on the social determinants of health (SDOH) of their patient cohorts, including factors receiving less attention, such as education level, employment status, insurance status, and socioeconomic status. METHODS: The PubMed/MEDLINE database was used to search for RCTs between 2020 and 2022 from 3 high-impact orthopaedic sports medicine-related journals: American Journal of Sports Medicine, Arthroscopy, and Journal of Shoulder and Elbow Surgery. The following information was extracted from each article: age, sex/gender, body mass index, year published, corresponding author country, and self-reported SDOH factors (race, ethnicity, education level, employment status, insurance status, and socioeconomic status). RESULTS: A total of 189 articles were analyzed. Articles originated from 34 different countries, with the United States (n = 66) producing the greatest number of articles. Overall, age (n = 186; 98.4%) and sex/gender (n = 184; 97.4%) were the factors most commonly reported, followed by body mass index (n = 112; 59.3%), race (n = 17; 9.0%), ethnicity (n = 10; 5.3%), employment status (n = 9; 4.8%), insurance status (n = 7; 3.7%), and education level (n = 5; 2.6%). Socioeconomic status was not reported in any of the articles analyzed. Articles from the United States report on SDOH factors more frequently than international articles, most notably race (24.2% vs 0.8%, respectively) and ethnicity (15.2% and 0%, respectively). CONCLUSIONS: RCTs from 3 high-impact orthopaedic sports medicine journals infrequently report on SDOH. CLINICAL RELEVANCE: Better understanding patient SDOH factors in RCTs is important to help orthopaedic surgeons and other practitioners best apply study results to their patients, as well as help researchers and our field ensure that research is being done transparently with relevance to as many patients as possible.

Upper limb neurodynamic mobilization disperses intraneural fluid in cervical nerve roots: A human cadaveric investigation.

BACKGROUND: Cervical radiculopathy is a common cause of neck pain with resultant intraneural edema and impaired nerve function. One strategy to treat radiculopathy is neurodynamic mobilization (NDM); however, little is known about the effect of this treatment on nerve tissue fluid dynamics. OBJECTIVE: Investigate the impact of upper limb, median nerve-biased NDM on longitudinal intraneural fluid dispersion in the C5,C6,C7 nerve roots in un-embalmed cadavers. DESIGN: In situ repeated measures. METHODS: Human cadavers (n = 8) were dissected to expose and inject C5,C6,C7 cervical nerve roots with a dying agent. Initial longitudinal dye spread was recorded after dye spread stabilization. Cadavers were taken through 150 repetitions of upper limb, median nerve-biased NDM followed by dye spread re-measurement. Paired-samples t-tests with Bonferroni correction (α = 0.017) were used to compare pre-vs post-NDM dye spread measurements at C5,C6,C7 nerve roots; a one-way repeated measures ANOVA (α = 0.05) was used to examine differences between change scores for C5,C6,C7 nerve roots. RESULTS: Median nerve-biased NDM resulted in significant intraneural longitudinal dye spread at C5 and C6 nerve roots of 0.6 ± 0.6 mm and 3.4 ± 3.9 mm, respectively (p < 0.014). Dye spread was not significant at C7 nerve root (0.4 ± 0.7 mm). There was no between root difference in change of longitudinal dye spread between C5, C6, and C7 nerve roots. CONCLUSIONS: The results of this study show median nerve-biased NDM produced internal fluid movement within C5 and C6 cervical nerve roots. Results provide insight regarding possible mechanism of action and feasibility of NDM in treatment of patients with cervical radiculopathy.

Triceps Tendon Rupture - A Novel Repair of an Uncommon Injury.

INTRODUCTION: Triceps tendon rupture is a rare injury accounting for <1% of all tendon injuries with varying repair techniques described. We present this novel repair to supplement available literature and help optimize the clinical outcomes for affected patients. We report this technique because it is unique in that we augmented our surgical fixation with a subtle variation in the described technique by repairing the deep portion of the triceps tendon as a separate step, maximizing the recreation of the anatomic footprint of the triceps. CASE REPORT: The patient is a 70-year-old Caucasian male presenting with pain, swelling, and ecchymosis around the elbow after the episode of injury. He also complained of a painful popping sensation whenever he ranged the elbow and an inability to extend, with pain and weakness any time he attempted elbow extension. Radiographs reviewed at his initial visit revealed a small osseous fragment approximately 5 cm proximal to the olecranon tip. Subsequent MR imaging confirmed our suspicion, showing a complete tear of the triceps tendon with hematoma at its insertion site and tendon retraction approximately 3 cm proximally. With the diagnosis of triceps tendon rupture conformed, we took the patient for primary tendon repair using suture with bone bridge and suture anchor, using elements from described techniques. Our technique was unique in that we performed repair of the deep and superficial triceps attachments as separate steps, in an endeavor to improve the anatomic reconstruction of the footprint and biomechanical strength. CONCLUSIONS: We combined findings from our review of the available literature with novel surgical techniques and suture design to maximize the patient outcome and minimize complications. The patient went on to have a very satisfactory functional recovery. We hope that this case report will complement the evidence-based care of these patients by orthopedic surgeons and lead to the best results possible.
