Recurrent dislocation of the ECU tendon in a golf player: release of the extensor retinaculum and partial resection of the ulno-dorsal ridge of the ulnar head.

A 20-year-old golf player who developed recurrent dislocation of the extensor carpi ulnaris (ECU) tendon is reported. The patient was successfully treated by release of the extensor retinaculum and partial resection of the ulno-dorsal ridge of the ulnar head, because the methods caused no redislocation and required only a brief period of rehabilitation.
