Mason type II or III radial head fractures treated by anatomical locking compression titanium plate

Objective To assess clinical outcomes of anatomical locking compression titanium plate for treatment of patients with Mason type Ⅱor Ⅲ radial head fractures. Methods A total of 28 patients from Jan. 2008 to Dec. 2011 with Mason typeⅡor Ⅲ radial head fractures were recruited in this clinical retrospective analysis. All of the patients were treated by open reduction and anatomical locking compression titanium plate fixation. Allograft bone grafts were performed in 4 of 28 cases and medial collateral ligaments were reconstructed in 8 cases. Results All of 28 patients were followed up. According to Broberg and Morrey Elbow Performance Index, the average score was 86 points(range, 46-100 points). The average flexion mobility was118°(range,95-135°), extension 20°(range, 0-30°), pronation 52°(range, 15-60°), supination 58°(20-70°). The results were excellent in 15 cases, good in 10 cases, fair in 3 cases, with an excellent and good rate of 89.3%. All patients recovered with good function of the elbows. One patient had moderate pain at the elbow, and 2 patients had some loss of strength of the elbow and wrist. Conclusion Open reduction and anatomical locking compression titanium plate internal fixation are option for Mason type Ⅱor Ⅲ radial head fractures, which provide firm internal fixation and the feasibility of early functional excercise.
