Abstract
Objective To evaluate the clinical outcomes of different internal fixation methods to treat adult radial neck fractures. Methods Twenty-one cases of Mason Ⅱ and Ⅲ radial neck fractures were treated with open reduction and internal fixation. Mini-plate and Kirschner-wire fixation was used in 16 cases and 5 cases, respectively. Elbow functions were evaluated and compared between the two groups. Results All patients were follow-up for 16 to 42 months (average 33 months). Nonunion occurred in one case with K-wire fixation, which was treated with mini-plate fixation 8 months after the first surgery. All other 20 cases achieved bone union. According to Broberg and Morrey score system, the mini-plate group had excellent results in 11 cases, good results in 4 cases and fair results in 1 case, with an overall excellent and good rate of 93.8%. The K-wire group had excellent results in 1 case, good results in 2 cases, fair results in 1 case and poor results in 1 case, with an overall excellent and good rate of 60.0%. Conclusion Open reduction and internal fixation is the most appropriate way to treat adult Mason Ⅱ and Ⅲ radial neck fractures. Mini-plate fixation is significantly better than K-wire fixation.
