Abstract
Twenty-nine wrists of 29 patients were treated with three procedures: distal ulnar resection (Darrach's procedure), distal ulnar recession, or hemiresection-interposition arthroplasty. The indications were pain and limitation of motion associated with primary osteoarthritis of the distal radioulnar joint, derangement after distal forearm bone fracture, Madelung's deformity, and distal radioulnar sprain. The age of the patients averaged 48.3 years. Follow-up averaged 1 year and 9 months. Radiographic evaluations were done preoperatively and postoperatively. Relief of pain was good in the wrists treated by Darrach's procedure; however, diminished grip strength and wrist instability occurred. Relief of pain in the wrists treated by distal ulnar recession and hemiresection-interposition arthroplasty was inferior to that of Darrach's procedure; however, postoperative grip strength increased and wrist instability did not occur.
