Palmar dislocation of scaphoid and lunate as a unit: case report with special reference to carpal instability and treatment

Abstract

A case of palmar dislocation of scaphoid and lunate as a unit is reported with a 3 1/2-year follow-up. Closed reduction was followed by redislocation after a week. Secondary open reduction could not prevent a dorsiflexed intercalated segmental instability deformity, which ended with arthritic changes in the wrist. A plea is made for early open reduction and internal fixation.
