Through an international survey, we assessed whether deciding to operatively treat an intra-articular distal radius fracture (DRF) is guided by identifiable patient and surgeon factors. In addition, we compared surgeons' treatment decisions with the American Academy of Orthopaedic Surgeons' Appropriate Use Criteria (AUC) treatment recommendations. This cross-sectional survey asked 224 surgeons to operatively or nonoperatively treat 28 hypothetical patients with radiographs of an intra-articular DRF. We randomized patient age (50/70 years), gender, mechanism of injury, activity level, and OTA/AO fracture type. We classified 6 fractures as "nonclinically significant displacement" and 22 as "potentially clinically significant displacement." Multilevel logistic regression analysis was performed. Odds ratios (ORs) and 95% confidence intervals (CIs) were reported. Statistical significance was P < 0.05. Patient factors independently associated with surgery included younger age (OR 6.7, P = 0.003), clinically significant fracture displacement (type B: OR 122, CI, 20-739, P < 0.001; type C: OR 59, CI, 12-300, P < 0.001), normal activity level (OR 5.0, P < 0.001), and high-energy mechanisms (OR 1.3, P = 0.002). Surgeon factors associated with recommending surgery included practicing outside the United States (Europe: OR 2.6, P < 0.001; "other": OR 4.8, P < 0.001). Hand surgeons most often selected surgery, as compared to orthopaedic trauma surgeons (OR 2.3, P = 0.001) and "other orthopaedists" (OR 2.2, P = 0.022). Thirty-seven percent of treatment decisions for patients with normal activity levels were rated by AUC recommendations as "rarely appropriate," which included 91% disagreement for 70-year-olds with nonclinically significant displacement. Surgeons use patient age and fracture displacement to make treatment recommendations for intra-articular DRF. We recommend that the AUC be updated to include these clinical factors as essential components in its algorithm. Therapeutic Level V.
