Scapholunate pathologies disrupt the normal kinematics of the wrist. Common causes of pain and dysfunction include ganglion cysts and scapholunate ligament injuries, which can progress to scapholunate advanced collapse (SLAC).
Scapholunate Pathologies
-
Ganglion Cysts
Ganglion cysts of the dorsal wrist are characterized by synovial metaplasia and herniation with capsular involvement. This common soft tumor most often originates from the scapholunate ligament with surgical indications for open or arthroscopic resection.
-
Scapholunate Ligament (SLL) Injuries
The scapholunate ligament (SLL) and associated joint are integral to wrist structure and function. Scapholunate ligament injuries may require ligament repair, reconstruction, or other surgical intervention to restore stability to the wrist.

Scaphoid Lunate Advanced Collapse (SLAC)
Scapholunate advanced collapse, or SLAC wrist, is a debilitating complication of a scapholunate injury that results in progressive osteoarthritic changes in response to abnormal kinematics of the wrist. For this advanced pathology, salvage procedures l...
