Bone-Retinaculum-Bone Autografts for Scapholunate Interosseous Ligament Reconstruction

Carpal instability arising from an injury to the scapholunate interosseous ligament (SLIL) is commonly seen and treated by hand surgeons. No technique to this date has proved to provide optimal results for primary repair of acute SLIL tear and the treatment of chronic tears of the SLIL. Recently, attention has shifted toward replacement of the dorsal aspect of the SLIL, which is the most structurally and functionally important aspect of the SLIL. This article describes the indications, surgical technique, postoperative treatment and expected results of the use of a bone-retinaculum-bone autograft procedure in the treatment of scapholunate instability.
