[Dorsal ligament reconstruction in scapholunate dissociation].

After discussion of the importance of the palmar, dorsal and interosseous ligaments in cases of scapholunate subluxation, the radiologic signs of this carpal instability are described. Four cases with this instability were treated successfully by reconstruction of the dorsal ligaments. In three instances ligament reconstruction was performed with the split tendon of the extensor carpi radialis brevis passed through drill holes in the scaphoid and lunate similar to the method reported by Dobyns.
