A Clinical Study of the Modified Thread Carpal Tunnel Release

Background: Previous studies have indicated that the thread carpal tunnel release (TCTR) is a safe and effective technique. Through a study on 11 cadaveric wrists, the TCTR procedure was modified and the needle control accuracy was improved to 0.15 to 0.2 mm, which is precise enough to preserve superficial palmar aponeurosis (SupPA), Berrettini branch, and common digital nerves. The aim of the present study was to verify the modified TCTR clinically. Methods: The modified TCTR was performed on 159 hands of 116 patients. The Boston Carpal Tunnel Syndrome Questionnaire was used for assessing the outcomes. Statistical analyses were used to compare the outcomes with the available data from the literature for the open and endoscopic techniques. Results: TCTR led to significant improvement in the short-term results, and the outcomes were better in long-term results compared with the open or endoscopic release. The SupPA, Berrettini branch, and common digital nerves were protected. There was no neurovascular com...
