Abstract
Treatment of isolated complete tear of the scapholunate ligament is challenging. The purpose of this study was to determine (1) whether delayed repair of only scapholunate ligament is an option without other reconstruction procedures and (2) whether functional outcomes are possible despite radiographic presence of arthritis. This study included patients who had complete ligament tear at exploration and underwent only scapholunate ligament repair without capsulodesis or tenodesis. Fifteen patients returned for clinical and radiographic examinations. Preoperatively, mean scapholunate gap was 2.9 mm and 4.58 mm on posteroanterior and tangential posteroanterior views, respectively. Postoperatively, the final mean gap was 2.5 mm and 3.9 mm on the posteroanterior and tangential posteroanterior views, respectively. The mean preoperative and final scapholunate angles were 74° and 72.6°, respectively. Seven patients had radiographic arthritis at final follow-up. Delayed scapholunate repair is possible after complete ligament tear. At long-term follow-up, clinical functional outcomes may not correlate with radiographic presence of degenerative arthritis.
