Background: One of the most feared complications following treatment of Dupuytren contracture is complex regional pain syndrome (CRPS). This study aims to provide a national perspective on the incidence of CRPS following treatment of Dupuytren contracture and identify patient factors to target for risk reduction. Methods: Using the Truven MarketScan databases from 2007 to 2016, individuals aged ≥18 years who developed CRPS within 1 year of treatment of Dupuytren contracture were identified using the International Classification of Disease diagnosis code for CRPS. Predictor variables included: age, sex, employment status, region, type of procedure, and concurrent carpal tunnel surgery. Multivariable logistic regression was used to analyze outcomes. Results: In all, 48 327 patients received treatment for Dupuytren contracture, including collagenase injection (13.6%); percutaneous palmar fasciotomy (10.3%); open palmar fasciotomy (3.9%); palmar fasciectomy with 0 (10.8%), 1 (29.2%), or multiple (19.6%) digit releases; or a combination of these procedures (12.8%). One hundred forty-five patients (0.31%) were diagnosed with CRPS at a mean of 3.4 months (standard deviation, 2.3) following treatment. Significant predictors of CRPS included female sex (odds ratio [OR], 2.02; P < .001), Southern region (OR, 1.80; P = .022), long-term disability status (OR, 4.73; P = .035), palmar fasciectomy with release of 1 (OR, 5.91; P = .003) or >1 digit (OR, 13.32; P < .001), or multiple concurrent procedures for Dupuytren contracture (OR, 8.23; P = .001). Conclusions: Based on national commercial claims data, there is a lower incidence of CRPS following treatment of Dupuytren contracture than previously reported. Risk factors identified should help with preoperative counseling and assist clinicians in targeting risk reduction measures.
