Introduction:
Smaller hand size has been shown to affect ease of instrument use and surgeon injury rates in multiple surgical subspecialties. Women have a smaller average hand size and are more often affected by this issue than men. The goal of this resident survey was to investigate whether hand size and gender impact self-reported difficulty with instrument use among orthopaedic surgery residents.
Methods:
Residents were surveyed about how often they experience difficulty using common orthopaedic instruments. Self-reported difficulty using surgical instruments was compared between residents with small glove (SG, outer ≤7.0) vs. large glove (LG, ≥ 7.5) sizes and between male and female residents.
Results:
One hundred forty-five residents (118 males and 27 females) completed the survey for a response rate of 3.7%. The SG group contained 35 residents, with 26 females and 9 males. The LG group contained 110 residents, with 1 female and 109 males. The SG group reported more difficulty than the LG group when using 3/6 instruments: the wire-cutting pliers (71.4% vs. 25.5%), universal T-handle chuck (65.7% vs. 21.4%), and large wire driver (60.0% vs. 24.8%). Female residents reported more difficulty than males for 5/6 instruments. Within the SG group, however, there was no difference in self-reported difficulty between female SG and male SG residents for 4/6 instruments.
Conclusions:
The predominantly male LG group reported significantly less difficulty than the more gender mixed though still predominantly female SG group. A subanalysis comparing males and females within the SG group found that there was no difference between SG female and SG male residents for 4/6 of the instruments, suggesting that glove size might impact reported difficulty independently from gender. Although the effect of glove size vs. gender is difficult to differentiate in this study, the high rate of difficulty experienced by male and female residents in the SG group should be considered by residency programs, surgeon educators, and instrument manufacturers as the field of orthopaedic surgery continues to become more diverse.
