Gender Trends in Authorship in 6 Major Orthopaedic Journals.

BACKGROUND:Historically, orthopaedic surgery has had low female representation, with <6% of practicing surgeons identifying as female. Although prior literature has illustrated gender disparities in first and last authorship as well as changes in gender representation over time, less attention has been paid to middle authorship. We hypothesized that trends in female authorship would reflect increasing female participation in orthopaedic surgery and orthopaedic subspecialties coinciding with an overall increase in female authorship. METHODS:Bibliometric information from articles published between 2011 and 2021 in 6 orthopaedic journals was extracted with use of the Web of Science. Collected data included author order, author names, affiliation, and corresponding author address. A gender was assigned with the use of Genderize.io, which is validated software, on the basis of author first name. Statistical analysis was performed with use of an analysis of variance for each journal, and linear regression was performed to determine trends, controlling for year. RESULTS:Among all included orthopaedic journals, female middle authorship increased by 5 percentage points, female first authorship increased by 4 percentage points, and female last authorship increased by 1 percentage point. Over the study period, the highest rate of female middle authorship (28%) was seen in the Journal of Pediatric Orthopaedics, whereas the lowest rate (16%) was seen in The Journal of Arthroplasty . We found that the 5 highest-producing female last authors were, on average, cited significantly less per publication than their male counterparts in all but 2 journals. CONCLUSIONS:Gender gaps exist within orthopaedic surgery as well as within its body of literature. Although this study highlights areas of growth, it also promotes further inquiry into research productivity and the availability of opportunity within orthopaedic surgery as a whole. The increase in female middle authorship overall and in each journal demonstrates momentum for future growth for women in the field of orthopaedic surgery.
