The carpal tunnel release is usually a curative treatment for the carpal tunnel syndrome (CTS), but not without complications, it may ranges from wound infection to nerve laceration. Study population included 150 patients (157 wrists) who had surgery for CTS. Patients were observed for the outcome and associated problems during and after operative procedure.
Thirty seven wrists (23%) developed complications, these complications were; intraoperative in 7 wrists, early postoperative (within first 2 weeks) in 10, and late postoperative (after 2 weeks) in 20.
This finding indicates that failure or complications following surgical release may occur, and in some situations may relate to the dissection or operating surgeon
