Abstract:
Replacement arthroplasty of the ulnar head is indicated primarily for stiffness and pain as a consequence of rheumatoid, degenerative, and posttraumatic arthritis of the distal radioulnar joint. It is also successfully used in the setting of previous failed excisional arthroplasty of the distal ulna. A distal ulnar hemiarthroplasty, which anatomically recreates the native ulnar head by employing an eccentric design, is discussed. The surgical technique includes a dorsal approach and careful repair of the soft tissue stabilizers.
