Ulnohumeral arthroplasty: results in primary degenerative arthritis of the elbow.

Our results with the ulnohumeral arthroplasty are presented. Seventeen patients were evaluated at an average followup greater than 36 months (range, 24-50 months). The average age of the patients was 52 years (range, 40-74 years). At final followup, 15 patients had complete pain relief at end ranges of motion whereas two patients had moderate pain after prolonged activity. Extension and flexion were improved by a mean of 12 degrees and 20 degrees, respectively, with a mean range of motion 14 degrees to 118 degrees. Postoperative radiographs showed a correctly placed drill hole with complete osteophyte resection. There were no neurologic or other complications and good stability of the elbow was observed in all patients. We think ulnohumeral arthroplasty is a good procedure for active patients with primary degenerative joint disease of the elbow.
