Gender differences among shoulder arthroplasty surgeons: past, present, and future

Background: Reducing differences in the gender representation of shoulder arthroplasty surgeons may help optimize patient care. This work aimed to determine (1) the current gender distribution of surgeons performing shoulder arthroplasty, (2) how gender relates to practice patterns among shoulder arthroplasty surgeons, and (3) how gender distribution has been changing over time. Methods: The Medicare Provider Utilization and Payment Data for the years 2012-2020 were used to identify orthopedic surgeons performing anatomic and reverse total shoulder arthroplasty (Current Procedural Terminology code 23472). The data set provides self-reported gender, credentials, National Provider Identifier, annual volume of all procedures (based on Current Procedural Terminology codes) that were performed >11 times in the calendar year, and location for all included providers. The data set was linked to the Medicare Physician Compare data set using National Provider Identifiers to determine hospital affiliations, year of medical school graduation, and graduating medical school. All included hospitals were queried to determine academic status (affiliated orthopedic residency or fellowship program). The American Shoulder and Elbow Surgeons (ASES) directory was reviewed to determine the gender breakdown of current members. Results: The number of surgeons performing >= 11 shoulder arthroplasties annually increased from 821 (13 women [1.6%]) in 2012 to 1840 (53 women [2.9%], P = .05) in 2019. One female surgeon ranked in the top 100 surgeons by shoulder arthroplasty volume in 2012 and in 2020. Female surgeons graduated more recently from medical school (mean, 2005) compared with male surgeons (mean, 1997; P < .001). About 10% of female surgeons (10.8%, 12 of 111) and male surgeons (9.1%, 229 of 2528) practiced at hospitals with orthopedic residents (P = .50). Female surgeons performing shoulder arthroplasty were less likely than male surgeons to perform total knee arthroplasty (29.4% vs. 54.1%, P < .001) and total hip arthroplasty (12.6% vs. 34.7%, P < .001). There were 86 female members of ASES (6.7%, 86 of 1275), with a significant difference in the proportion of women in differing membership categories (P = .017). Discussion and conclusion: A diverse cohort of high-volume shoulder replacement surgeons is integral to delivering high-quality shoulder arthroplasty. Currently, the proportion of women performing high-volume shoulder replacement in the United States is small, with little improvement in recent years. However, women performing shoulder arthroplasty are younger and are often involved in academic practices, and the membership of ASES is increasingly female. Continued efforts to promote orthopedics-and to mentor female residents and medical students interested in shoulder surgery-may bring real change to the gender differences among shoulder replacement surgeons over the comLevel of evidence: Level IV; Descriptive Epidemiology Study Using Large Database (c) 2024 Journal of Shoulder and Elbow Surgery Board of Trustees.
