Scapholunate ligamentous injuries are the most common interosseous carpal injuries within young active individuals, with an incidence up to 54% after distal radius fractures. If left untreated, they can lead to scapholunate ligament advanced collapse. Controversy exists in the management of acute scapholunate ligament injuries. In this article, we review the current concepts in diagnosis, classification, and surgical management of these injuries. [ABSTRACT FROM AUTHOR]

In athletes, scapholunate injuries may be misdiagnosed as wrist sprains which over time almost invariably lead to scapholunate advanced collapse (SLAC) of the wrist. In this setting, arthritic changes progress from the radioscaphoid joint to the lunocapitate interval, usually preserving the radiolunate articulation. Treatment options for SLAC range from nonoperative alternatives to wrist denervation, limited intercarpal fusions, proximal row carpectomy, and total wrist fusion. This article describes four-corner fusion and proximal row carpectomy as 2 widely used and successful options for the management of SLAC. [ABSTRACT FROM AUTHOR]
