Abstract | BACKGROUND: Radial head fractures often pose therapeutic dilemmas. We present the early results of patients who underwent radial head replacement with the MoPyC prosthesis (Bioprofile, Tornier, Saint-Ismier, France).MATERIALS AND METHODS: We re-evaluated patients who underwent post-traumatic radial head resection and implantation of the MoPyC prosthesis due to pain and motion restriction. All patients underwent radiographic evaluation. Clinical evaluation was performed using the Broberg-Morrey and the Mayo Elbow Performance Score (MEPS) scales.RESULTS: Thirty-two patients (20 men, 12 women; mean age, 54 years; 22 dominant upper limbs) were evaluated. Twenty had a comminuted radial head fracture (Mason IV, 15; Mason III, 5), 2 from radial head fracture malunion, and 10 had complex elbow injuries (comminuted radial head fractures with ligamentous ruptures with or without coronoid process fractures). Mean follow-up was 27 months (range, 21-46 months). The mean results at the latest follow-up were flexion-extension, 130° (range, 105°-150°); pronation, 74° (range, 60°-80°); and supination, 72° (range, 60°-80°). No laxity was evident during valgus and varus stress tests. Mean grip strength was 96% of the contralateral side. Broberg-Morrey scores were excellent in 33%, good in 44%, and fair in 23%. MEPS results were excellent in 80%, good in 17%, and fair in 3%. There were 6 cases of periprosthetic lucencies or osteolysis of the radius without any clinical signs of loosening.CONCLUSIONS: Radial head replacement with the MoPyC pyrocarbon prosthesis (when performed in carefully selected patients) yields satisfactory results regarding range of motion and function of the elbow joint. |
