Scapholunate Ligament Injuries

Abstract

Injuries to the scapholunate interosseous ligament (SLIL) complex can result in a predictable cascade of incongruous motion in the carpus that leads to radiocarpal degeneration. Both acute traumatic impact and repetitive motion can render the SLIL insufficient. A thorough understanding of SLIL anatomy is required for appropriate diagnosis and treatment. Here, we review scapholunate ligament anatomy, prevention strategies, methods of diagnosis, nonoperative and operative treatments and outcomes. A myriad of treatment options exist for each stage of the SLIL injury, and management should be an open discussion between the patient and physician.
