Combined Carpal Tunnel Release and Palmar Fasciectomy for Dupuytren’s Contracture Does Not Increase the Risk for Complex Regional Pain Syndrome

Background: Hand surgery dogma suggests that simultaneous surgical treatment of carpal tunnel syndrome (CTS) and Dupuytren’s contracture (DC) results in an increased incidence of Complex Regional Pain Syndrome (CRPS). As a result, many surgeons do not perform surgery for the two conditions concurrently. Our goal was to determine the extent of this association. Methods: We identified all patients undergoing surgical treatment for CTS, DC, or both between April 1982 and March 2017 using the Indiana Network for Patient Care (INPC), a large, multi-institutional, statewide information exchange. Demographics, comorbidities, and 1-year post-operative incidence of CRPS were recorded. Results: A total of 51,739 (95.6%) patients underwent carpal tunnel release (CTR) only, 2,103 (3.9%) underwent palmar fasciectomy (PF) only, and 305 (0.6%) underwent concurrent CTR and PF. There was no difference in the likelihood of developing CRPS (p=0.163) between groups. Independent risk factors for developing CRPS were younger age, anxiety, depression, epilepsy, gout, and history of fracture of the radius, ulna, or the carpus. Conclusions: Concurrent CTR and PF is not associated with an increased risk for developing CRPS. Patient demographics, medical comorbidities, and a history of upper extremity trauma are associated with the development of CRPS after surgery and should be discussed preoperatively as potential risk factors
