Jeff Ecker Hand & Wrist Surgeon

The scaphoid and the lunate are two adjacent carpal bones in the wrist joined by the scapholunate ligament.  An injury to the scapholunate ligament can cause these bones to dissociate or ‘separate’.  This separation may be dynamic (occurring under load) or static (constant). This video explains what carpal instability is, the symptoms and the treatment options available.
