Abstract
Background: The purpose of this study was to identify differences related to race in preoperative and intraoperative findings of patients undergoing operative treatment for shoulder instability. Methods: Data from the Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Instability cohort were used. Of 1010 patients, 995 provided race and ethnicity information and were included in the analyses. Demographic characteristics, injury history, radiographic and intraoperative findings, and preoperative patient-reported instability, pain, and function were compared (1) between white and minority patients and (2) in a subgroup analysis between white patients and the 3 largest minority groups. The Distressed Communities Index (DCI) score was recorded for each patient's home ZIP code. Multiple logistic regressions were performed to determine whether models consisting of race/ethnicity, insurance carrier, and/or DCI score were predictive of bone and cartilage loss at the time of surgery. Results: Compared with white patients, a greater percentage of US minority patients had ≥2 dislocations (68.0% vs. 57.1%, P =.01), which corresponded with more frequent articular cartilage lesions (62.2% vs. 51.0%, P =.007) and increased frequencies of glenoid bone loss > 10% (16.2% vs. 8.7%, P =.03) and Hill-Sachs lesions (68.6% vs. 56.0%, P =.004). Specifically, when compared with white patients, African American and Asian patients showed significantly increased frequencies of glenoid bone loss > 10% (19.7% of African American patients, 18.4% of Asian patients, and 8.9% of white patients; P =.01) and Hill-Sachs lesions (65.6%, 71.7%, and 52.4%, respectively; P =.02). Race was an independent predictor of articular cartilage lesions (P =.04) and the presence of Hill-Sachs lesions (P =.01). A higher DCI score (P =.03) and race (P =.04) were both predictive of having glenoid bone loss > 10%. Conclusion: We found that minority race was associated with increased number of preoperative dislocations and increased frequency of articular cartilage and Hill-Sachs lesions at the time of surgery, and both minority race and an increased DCI score were associated with glenoid bone loss > 10%. Further research is needed to understand the underlying reason for these differences and to optimize care for all patients with shoulder instability.
