The scapholunate ligamentous complex consists of the scapholunate interosseous ligament and the surrounding extrinsic ligamentous system. In cases of chronic scapholunate instability, stabilizing the extrinsic ligaments is crucial. This article presents an arthroscopic capsuloligamentous reinforcement plicature that focuses on tightening the volar scapholunate extrinsic ligaments, namely the radioscaphocapitate ligament and long radiolunate ligament, along with indirect tightening of the volar scapholunate interosseous ligament. Although it may be challenging to differentiate the effect of the volar extrinsic plicature from a dorsal capsular reinforcement when both are applied, the volar extrinsic plicature can serve as a beneficial addition to dorsal capsular reinforcement techniques for complex scapholunate instability.
