Plate Fixation for Fractures of the Coronoid Process of the Ulna

ABSTRACT

PURPOSE: The purpose of this study was to evaluate the results of eight cases of coronoid process fractures that were fixed with a plate. MATERIALS AND METHODS: Eight coronoid process fractures were treated by plating and these cases were reviewed retrospectively. Six patients were men and two were women. The average age was 41 years (range 22-79) at the time of injury. According to Regan's classification, there were five type 2 and three type 3. According to O'Driscoll's classification, there were five anteromedial type and three base type. Open reduction and internal fixation with a plate were performed through a medial approach by splitting of the two heads of the flexor carpi ulnaris. The patients were follow-up for a mean of 15.8 months (range 6-25). We evaluated the clinical outcomes with using the Mayo Elbow Performance Score. RESULTS: The average active motion of the elbow joint was 120 degrees. The average Mayo Elbow Performance Score was 86.9. There were 5 excellent results, 1 good result and 2 fair results. SUMMARY: Plating through a medial approach of the elbow provided stable fixation and satisfactory union for treating displaced coronoid process fractures with the unstable elbow.
