title: Thumb metacarpophalangeal joint ligament reconstruction with a triangular tendon graft in posttraumatic chronic instability.
abstract: The purpose of this study was to report the results of static triangular ligament reconstruction, in thumb metacarpophalangeal (MCP) joint chronic posttraumatic laxity using a tendon graft with a proximal apex in ten patients. The mean postoperative follow-up was 40.2 months. The mean postoperative thumb MCP joint stress testing was 43° less than before surgery, and 6.5° less than in the non-injured hand. The mean range of flexion was 10.5° lower in the operated thumb than in the contralateral one, and the mean range of extension was 8° lower. Minimal differences in the values of the Kapandji score, grip and key-pinch strength were found. The preoperative pain became an occasional discomfort after surgery. All patients had a subjective sense of stability until final follow-up. All patients returned to their work or daily activities.
