摘要目的 探讨锁定加压钢板(LCP)切开复位内固定治疗老年桡骨远端不稳定性骨折的效果。方法 选择老年桡骨远端不稳定性骨折患者17例，手术行掌侧入路骨折切开复位、LCP内固定治疗并观察其疗效。结果 17例患者全部获得随访，随访时间7～16个月，平均12.6月。X线片示骨折于术后11.4周达临床愈合。根据腕关节功能及X线片测量进行综合评定：优12例，良4例，差1例，优良率94.1％。结论 切开复位掌侧LCP内固定是治疗桡骨远端不稳定骨折的有效方法。

abstractsObjective To study the clinical effect of locking compression plate fixation in treatment of the elders with unstable fractures of the distal radius. Methods 17 cases with unstable distal radius fractures were treated by volar locking compression plate. The function of the carpal joints and the bone healing conditions were evaluated after operations. Results All cases were followed-up for 7 to 16 months ( mean 12. 6 months). Union was obtained in all the patients after 11.4 weeks. The clinical outcomes were evaluated according to modified X-rays and wrist assessment. 12 cases were graded as excellent and 4 as good. 1 case were graded as poor. The overall satisfactory rate was 94. 1％. Conclusion The unstable distal radial fractures could be effectively treated with open reduction and LCP fixation through volar approach.
