Surgical treatment of anteromedial facet fracture of coronoid process of ulna

Abstract

Objective To investigate the diagnosis and treatment of anteromedial facet fracture of coronoid process of ulna. Methods From June 2011 to December 2013, 10 cases of anteromedial facet fracture of coronoid process of ulna were treated. There were 7 males and 3 females, with age ranging from 19 to 52 years (mean, 33.8 years). All the fractures were typeⅡaccording to O'Driscoll classification, including 5 cases of subtype-1, 4 cases of subtype-2 and 1 case of subtype-3. Anteromedial facet fracture of coronoid process of ulna was fixed by mini plate and lateral collateral ligament was repaired by anchor in all the patients. Results All the patients were follow-up for 12 to 28 months with an average of 15.8 months. The average flexion was 121° (range, 90° to 140°), the average extension loss was 18° (range, 0 to 50°), the average pronation was 70° (range, 50° to 90°), and the average supination was 69° (range, 51° to 90°). According to MEPS elbow performance score, the results were excellent in 5 cases, good in 4 cases and fair in 1 case. Conclusion Accurate diagnosis of anteriomedial facet coronoid fracture, early mini plate fixation and anchor repair of the lateral collateral ligament can achieve satisfactory clinical results.
