Acute Carpal Tunnel Syndrome in Inpatients With Operative Distal Radius Fracture.

Abstract

Acute carpal tunnel syndrome (CTS) may occur concomitantly with distal radius fracture (DRF) and is often managed with carpal tunnel release (CTR). Carpal tunnel syndrome may also develop postoperatively after DRF fixation. The authors sought to determine the rate of CTS with DRF, prophylactic CTR, and postoperative development of CTS. Furthermore, they also sought to identify predictors of these. The Nationwide Inpatient Sample database was queried (2002 to 2014) to identify adult inpatients undergoing surgical fixation of DRFs. They were segregated by the presence of CTS and further stratified by the timing of CTR in relation to DRF fixation. Those with a CTS diagnosis undergoing CTR on the same day as or prior to DRF fixation were classified as having CTS concomitantly. Patients undergoing CTR without a CTS diagnosis were considered prophylactically released. Carpal tunnel releases on any day after fracture fixation were considered complications. The authors identified 275,052 inpatients who had fixation of DRFs. Of these, 11,816 patients (4.3%) had CTS concomitantly. A total of 530 patients developed CTS after their DRF fixation (0.3%). Of those without CTS, 4420 patients (1.6%) underwent prophylactic CTR. Male sex, age younger than 50 years, and polytrauma status were associated with concomitant CTS and prophylactic CTR. Age younger than 50 years and polytrauma status were associated with postoperative development of CTS. The authors identified the rate of concomitant CTS, prophylactic CTR, and CTS developing postoperatively in inpatients undergoing DRF fixation. As early recognition and treatment optimizes outcomes after acute CTS, these data draw attention to the high rate of CTS and may be useful to surgeons treating patients with DRFs.
