人工桡骨头置换治疗成人桡骨头粉碎性骨折的研究

目的 探讨桡骨头粉碎性骨折行人工桡骨头置换的早期疗效.方法 回顾性分析2007-2010年,11例桡骨头粉碎骨折患者应用LINK单极金属桡骨头置换假体行人工桡骨头置换术的疗效.肘关节功能以BrobergMorrey肘关节功能评分进行评定.结果 随访时间平均24.5个月.本组平均手术时间104 min,平均失血量180ml.肘关节评分:优7例,良2例,可1例,差1例,肘关节屈伸范围82.3°～161.4°,前臂最大旋前60.5°,最大旋后74.3°,无脱位及感染发生.结论 人工桡骨头置换治疗桡骨头粉碎性骨折简便易行,早期临床效果良好.

Radial head replacement for comminuted fracture of radial head in adults

Objective To evaluate the early clinical effect of radial head replacement for comminuted fracture of radial head.Methods Eleven patients with comminuted fracture of radial head(classified as Mason Ⅲ and Ⅳ) underwent radial head replacement from 2007 to 2010.The unipolar mental radial head prosthesis(LINK,Germany) was used for replacement.Elbow function was assessed by Broberg-Morrey elbow score.Results All cases were followed up for average 24.5months.The mean operation time was 104min and mean blood loss was 180ml.According to the Broberg-Morrey elbow score,7cases were excellent,2 good,1 fair and 1 worse.The average range of motion(ROM) of the elbow was 82.3° to 161.4°,maximum pronation of forearm was 60.5°,maximum supination 74.3°.No dislocation and infection was found in this group of patients.Conclusion Radial head replacement is an alternative procedure for comminuted radial head fracture with satisfactory early clinical efficacy.
