外固定架治疗桡骨远端粉碎性骨折的疗效分析

目的:探讨闭合手法复位外固定架治疗桡骨远端粉碎性关节内骨折的临床疗效。方法:对29例桡骨远端粉碎性关节内骨折,通过外固定架的牵伸辅助复位,矫正桡骨的短缩、成角移位,恢复关节面的解剖关系,利用外固定架维持复位后的位置并进行功能练习。术后定期进行X线和腕关节功能的评价。结果:29例均获得随访,随访时间3~12个月,平均6.5个月。根据Aro功能评价:优9例,良17例,可2例,差1例,优良率89.66%。结论:外固定架能很好维持复位后的位置,恢复桡尺骨的相对长度和关节面的平整,使腕关节功能得到良好的恢复,因此是治疗桡骨远端粉碎性关节内骨折的有效方法。

Analysis of therapeutic effects of external fixatior for the treatment of comminuted intra-articular fractures of distal radius

Objective:To study therapeutic effects of close reduction combined with external fixatior for the treatment of unstable comminuted intra-articular fractures of distal radius.Methods:The fractures of twenty-nine patients were reduced under the extraction of external fixtor,and the shortness or angulation displacement of radius was corrected to reach anatomical reduction of joint surface.After reduction,the external fixator was still used and exercises were done at the 1st day after operation.X-ray examination and functional assessments of wrist joint were performed at different months.Results:All the patients were followed up from 3 to 12 months,with an average of 6.5 months.According to Aro assessment,9 patients reached excellents,17 good,2 fair and 1 bad.The excellent-and-good rate was 89.66%.Conclusion:External fixator is effective to recover and maintain anatomic reduction of wrist joint so as to ensure its function recovery,which is a better method to treat comminuted intra-articular fractures of distal radius.
