肌筋膜瓣对前臂骨连接的疗效观察

Clinical efficacy of myofascial flap in the treatment of radioulnar synostosis

目的探讨创伤后尺桡骨骨连接的防治方法。方法对2006年4月至2012年4月21例创伤后尺桡骨间骨连接凿除后使用前臂肌筋膜瓣进行间隔以预防骨连接复发。结果21例患者术前平均旋前和旋后角度为14°和5°，术后为65°和70°，经过6～17个月（平均11个月）的随访，旋转范围从术前的15°改善至130°，未出现骨性连接复发，所有患者治疗效果满意。结论骨性连接凿除后使用前臂肌筋膜瓣进行间隔能够有效地防治创伤性骨连接。

Objective To discuss our experience in treatment of posttraumatic radioulnar synostosis. Methods Twenty-one patients with posttraumatic radioulnar synostosis were treated with synostosis resection and in-terposition of forearm myofascial flap from 2006 to 2012. Results The mean preoperative pronation and postopera-tive pronation was 14° and 65° before treatment, 5° and 70° after treatment. The patients were followed up for 6-17 months, 11 months in average. The average arc of rotation improved from 15° to 130°. No case of recurrence was found. Conclusion Synostosis resection and interposition with forearm myofascial flap is an effective technique for the treatment of posttraumatic radioulnar synostosis.
