Scapholunate instability following dorsal wrist ganglion excision

Description: Ganglions on the dorsum of the wrist have been shown to originate from the scapholunate joint, often with direct attachment to the scapholunate interosseous ligament (SLIL). It has long been recognized that nonsurgical techniques for the treatment of dorsal wrist ganglia are unreliable with a high recurrence rate. Surgical intervention is often necessary. It has been recommended that surgical excision of the ganglion should be accompanied by excision of a small cuff of surrounding dorsal joint capsule, and removal of all attachments of the ganglion to the SLIL that are thought to minimize recurrence rate. While excision of the dorsal carpal ganglion is a common operation performed on the wrist, carpal instability is rarely considered a complication of this surgery.
