Objective: High surgeon procedural volume has been linked to better outcomes for a variety of surgical procedures, but the impact of surgeon volume on outcomes of Dupuytren surgery remains uncertain. Materials and Methods: We used data from a quality-of-care registry from 6 hand surgery practice sites between 2011 and 2014. We included 561 patients with the Dupuytren disease who underwent fasciectomy (71%) or percutaneous needle fasciotomy (29%) by 16 hand surgeons. Outcomes were the degree of residual contracture and adverse events assessed at 6 to 12 weeks after treatment. Relations between volume and outcomes were examined using linear and logistic regression models, with adjustment for patient characteristics and the type of procedure. Nonlinearity was assessed with restricted cubic splines. Results: Overall, mean residual contracture (total active extension deficit) at follow-up was 24°, which corresponded to a postprocedure improvement of 65%. Forty-seven percent of patients experienced at least 1 adverse event, with neuropraxia (12%), scar sequelae (12%), and wound healing problems (8%) being the three most common events. Surgeon volume was inversely related to the degree of residual contracture: Every 58 additional procedures performed annually were associated with 5° less residual contracture at follow-up (P, .03). Moreover, surgeon volume had an inverse effect on overall events (odds ratio per 50 additional procedures, 0.86, P, .01). Conclusions: Even among experienced hand surgeons, patients treated by surgeons performing high volumes of Dupuytren surgery had better outcomes in terms of residual contracture and adverse events. The findings of this study suggest that surgeons may improve outcomes by increasing their annual procedural volume for these specific interventions.
