Abstract

PURPOSE: To evaluate the use of post-arthrography computed tomography in examining wrist ligament injuries. MATERIALS AND METHODS: Thirty consecutive patients who had a history and clinical findings suggestive of ligamentous injuries of the wrist were examined. Fourteen men and sixteen women (average age 35 years) were enrolled in this study. The evaluation concentrated on the detection and precise localization of the ligament lesions in the triangular fibrocartilage (TFC), the scapholunate ligament (SLL) and the lunotriquetral ligament (LTL). RESULTS: For TFC, SLL and LTL lesions, arthro-CT showed a sensitivity 96%, 90% and 85.7%, and a specificity 80%, 90% and 91.3%, and an accuracy 93.3%, 90% and 93.3%, respectively. CONCLUSION: Arthro-CT may be a useful imaging method for evaluating intra-articular ligament injuries of the wrist.
