title: The role of three-ligament tenodesis in the treatment of chronic scapholunate instability.
abstract: Restoring ligamentous control in dissociative carpal instability is a major issue in protecting against osteoarthritis. We present clinical and radiological results for 20 patients who underwent flexor carpi radialis three-ligament tenodesis and were prospectively reviewed at a mean follow-up of 25.1 months. Three-ligament tenodesis significantly relieved pain and increased grip strength, wrist function at the expense of joint stiffness. This improvement was not seen in cases of dynamic instability. However, ligamentous loosening did result in rapid recurrence of radiological anomalies and frequent complications. This study challenges the long-term benefit of three-ligament tenodesis in both dynamic and static chronic scapholunate instability.
