Elbow osteoarthritis: Prognostic indicators in ulnohumeral debridement—The Outerbridge-Kashiwagi procedure

A consecutive series of 43 patients (44 elbows) underwent ulnohumeral debridement for elbow osteoarthritis. Thirty-five patients (36 elbows) were reviewed after a mean follow-up of 39 months. Eighty-one percent of patients were satisfied, with 12 good, 19 fair, and 5 poor outcomes. The mean flexion/extension arc, pain score, and locking were all significantly improved, but a significant number of patients had rest pain. Patients who had symptoms for less than 2 years, considerable preoperative pain, or cubital tunnel syndrome had a significantly increased chance of a good outcome. The absence of preoperative locking was associated with a significantly increased chance of a poor outcome. A history of trauma, preoperative range of movement, and radiograph score did not predict outcome. (J Shoulder Elbow Surg 2001;10:557-60.)
