摘　　要：目的报告双极桡骨小头假体置换治疗严重桡骨小头粉碎性骨折的初步临床结果。方法自2002年8月～2005年6月采用双极人工桡骨小头假体(浮动杯假体)置换的方法治疗MasonⅢ、Ⅳ型桡骨小头骨折10例,新鲜骨折9例,陈旧性骨折1例。结果所有患者随访6～40个月,平均14.9个月,肘关节屈伸平均133.5°/9.0°,前臂旋前/旋后平均78.5°/84.0°,3例遗留肘关节轻度疼痛,1例肘关节轻度外翻不稳,3例肘关节轻度乏力。Broberg-Morrey肘关节功能评分平均93分,优6例,良3例,可1例,优良率为90%。结论双极桡骨小头假体置换治疗难以重建的桡骨小头骨折的近期效果满意,远期疗效有待进一步随访。Objective To report the preliminary clinical results of treatment of severely comminuted radial head fractures by replacement with floating cup radial head prosthesis. Methods In the period from August 2002 to June 2005, replacement with floating cup radial head prosthesis was performed to treat 10 eases of Mason Ⅲ, Ⅳ radial head fractures, of whom 9 were acute fractures and 1 old. Results All the patients were followed up for 6 to 40 months （mean 14. 9 months） . The mean flexion/extension of the elbow was 133.5°/9. 0°, while the mean pronation/supination of the forearm was 78.5°/84.0°. There were 3 cases of mild pain, 1 case of mild valgus instability in the elbow and 3 cases of mild weakness. The Broberg and Morrey elbow scores averaged 93. The result was excellent in 6 cases, good in 3 and fair in 1, the excellent and good rates were 90%. Conclusion The replacement with floating cup prosthesis shows satisfying preliminary clinical outcome in the treatment of radial head fractures unable to be reduced, while its long-term result needs further follow-up.
