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.
