COMPARISON OF LIGAMENT Z-PLASTY AND CONVENTIONAL SURGERY FOR THE TREATMENT OF CARPAL TUNNEL SYNDROME. A RANDOMIZED CLINICAL TRIAL.

Background: Conventional surgery performed to treat carpal tunnel syndrome (CTS) is associated with complications such as pillar pain or loss of strength. This study aimed to compare the incidence of pillar pain between two techniques at the 3-week and 6-month follow-up and to determine any differences in the recovery of grip strength (GS), pinch strength (PS), and Boston Carpal Tunnel Questionnaire (BCTQ) scores.

Methods: This randomized clinical trial comprised 109 patients of which 55 underwent ligament Z-plasty and 54 underwent conventional surgery (longitudinal section of the transverse carpal ligament without posterior closure).
