外固定架治疗桡骨远端不稳定型骨折

摘要

目的：探讨外固定支架在桡骨远端不稳定性骨折治疗中的效用。方法：对58例有完整随访资料的桡骨远端不稳定性骨折患者进行分析研究，在术后1~2年，测定腕关节的活动范围和影像学指标，对腕关节进行Gartland-Werley功能评分。结果：所有病例均在3月内临床愈合，患者腕关节的背伸和尺偏活动范围显著小于正常腕关节（ P﹤0.05），掌屈、桡偏、旋前、旋后差异无统计学意义（P>0.05），桡骨高度和尺偏角与对侧正常腕关节相比无统计学差异（P>0.05），掌倾角显著小于正常腕关节（P﹤0.05）。结论：外固定支架应成为治疗桡骨远端不稳定性骨折的首选，其固定牢靠，创伤小，疗效好，并发症少，值得推广。%Objective To evaluate the efficacy of the external fixation in treating unstable distal radius fractures. Method 58 cases of unstable distal radius fractures diagnosed were treated with external fixation. Wrist movement range and radiographic index were measured and wrist funtion was evaluated by the Gartland -Werley criteria 1 ~2 years after surgery. Results All the cases were cured within 3 months,Patients wrist dorsiflexion and ulnar deviation range was significantly less than the normal activities of the wrist(P﹤0. 05),there was no significant difference in the movement range of flexion,pronation,supination and radial deviation(P>0. 05),and the difference was no significant in the radial height and ulnar inclination between the treated wrist joint and the normal hand( P>0. 05 ). Nevertheless,the recorvery of thewrist extension,ulanr deviation and palm tilt was limeted,significantly smaller than the normal(P﹤0. 05). By the Gartland-Werley criteria,the excellence rate was 93. 1%. Conclusion External fixation should be the first choice of the treatment for unstable dis-tal radius fractures,because it is rigid,less invasive,good effects,less complications,it is worthy of promoting.
