Trapeziometacarpal Arthrosis: Predictors of a Second Visit and Surgery

Abstract

Trapeziometacarpal arthrosis is expected with advancing age and a limited percentage of people seek medical attention for it. We studied patients after their first appointment to address trapeziometacarpal arthrosis with a hand surgeon to determine factors associated with return for a second visit and eventual election of operative treatment. A billing database identified 306 patients in the practice of three hand surgeons with a new diagnosis of TMC arthrosis and no associated diagnoses. Bivariate and multivariable logistic regression analyses sought factors associated with a second visit and operative treatment among demographic and visit related factors. One hundred and forty-three patients (47 %) returned for one or more additional visits and 46 (15 %) eventually elected operative treatment within the study period. Independent predictors of a return visit included injection at first visit, splint at first visit, and doctor’s recommendation for a return visit. The predictors of surgery were treating surgeon and prescription of a splint at the first visit, but splint at first visit was only predictive for one of the three surgeons. When patients first learn about their trapeziometacarpal arthrosis, the behavior of the hand surgeon may have a strong influence on return visits and eventual choice of operative treatment.
