Replacement of the Distal Radioulnar Joint

The function of the distal radioulnar joint (DRUJ) is to allow lifting of the forearm in all positions. Loss of the DRUJ leads to painful impingement of the radius on top of the stump of the ulna, limiting the activities of the patient. Restoration of the function of the forearm in these cases is achieved by a total replacement of the DRUJ. Cases illustrating the technique and long-term results are presented.
