Lack of race/ethnic minority representation in ulnar collateral ligament reconstruction in baseball athletes: a systematic review.

Abstract

Objectives: To assess the reporting and representation of ethnic and racial minorities in comparative studies of ulnar collateral ligament (UCL) injuries and treatment in baseball athletes.

Methods: A systematic review of the literature was conducted using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) reporting guidelines. The literature search was conducted by two independent reviewers using the PubMed, Scopus, and Cochrane Library databases. Studies were included if they were UCL of the elbow clinical comparative studies, including randomized clinical trials, cohort studies, case series, and epidemiological studies. Studies were excluded if they were related to ulnar collateral ligament of the thumb, lateral ulnar collateral ligament of the elbow, biomechanical studies, non-surgical studies, non-baseball studies, and systematic reviews and meta-analyses. The Methodological Index for Non-Randomized Studies (MINORS) criterion was used to assess quality of studies included.

Results: A total of 108 studies were included for analysis, of which only one reported race and ethnicity in their demographics. Additionally, of the 108 studies included, only four reported Country of Origin, a subset of Race and Ethnicity, in their demographics.

Conclusion: Race and Ethnicity demographics are scarcely reported in comparative studies evaluating ulnar collateral ligament reconstruction. Future studies evaluating similar populations should strongly consider reporting racial and ethnic demographics as this may provide clarity on any potential effect these might have on post-surgical outcomes, particularly in high-level pitchers.
