Repair of scapholunate dissociation as described by Palmer, Dobyns, and Linscheid. A, Radial view of wrist showing position of flexor carpi radialis muscle-tendon unit. B, Dorsal view of wrist with overhang of radius cut away shows tear of radioscapholunate ligament and separation of scaphoid and lunate. C, Both views show tunnels in scaphoid and lunate for tendon passage; first, or lunate, passage (volar to dorsal) of flexor carpi radialis tendon graft slip, and first Kirschner wire stabilization of lunate to radius, done after tendon graft is passed. D, Second, or scaphoid, passage (dorsal to volar) of flexor carpi radialis tendon graft. E, Carpals aligned in slightly overreduced position with each other and with radius. Position of scaphoid had been stabilized by Kirschner wire through radius into scaphoid and capitate. F, Volar and lateral views of wrist showing third, or radial, passage (volar and intraarticular to volar and extraarticular) of tendon graft, which is sutured to itself. SEE TECHNIQUE 69.45.
