Open debridement and radiocapitellar replacement in primary and post-traumatic arthritis of the elbow: a multicenter study

Background rtem and clinical studies have shown an early and prevalent involvement of the radiohumeral joint in primary and secondary arthritis of the elbow. The lateral resurfacing elbow (LRE) prosthesis has recently been developed for the treatment of lateral elbow arthritis. However, few data have been published on LRE results. als and methods pective multicenter study was designed to assess LRE preliminary results. There were 20 patients (average age, 55 years). Preoperative diagnosis were primary osteoarthritis in 11 and post-traumatic osteoarthritis in 9. All patients underwent open debridement and LRE prosthesis. Patients were evaluated preoperatively and postoperatively with the Mayo Elbow Performance Score (MEPS), modified American Shoulder Elbow Surgeons (m-ASES) elbow assessment, and the Quick Disabilities of the Arm, Shoulder and Hand (Quick-DASH). Mean follow-up was 22.6 months. s last follow-up, the mean improvement of MEPS and m-ASES was 35 (P = .001) and 34 (P = .001) respectively; the average Quick DASH decreased by 29 (P = .001). Average range of motion was improved by 35° (P = .001). MEPI results were excellent in 12 patients, good in 2, and fair and poor in 3 each. Mild overstuffing was observed in 5 patients, and an implant malpositioning in 3. The implant survival rate was 100%. sion owed promising results in this prospective investigation. Most patients had an uneventful postoperative course and have shown a painless elbow joint, with satisfactory functional recovery at short-term follow-up. Further studies with longer follow-up are warranted.
