目的 比较桡骨远端不稳定骨折应用手术和石膏外固定治疗的临床效果。方法 选取桡骨远端不稳定骨折患者300 例，平均分成手术组与石膏外固定组各150例，手术组应用掌侧入路切开复位钢板螺钉内固定术治疗，石膏外固定 组应用石膏外固定治疗，对比两组患者治疗后的临床效果。结果 手术组的优良率为90.7%，石膏外固定组的优良率 为72.7%，对比两组差异显著，有统计学意义（P<0.05）。结论 相比于石膏外固定治疗，手术治疗桡骨远端不稳定 骨折的临床效果更为显著，值得推广。

Objective To compare the clinical effect of surgical treatment of unstable distal radius fractures treated with external fixation and plaster external fixation. Methods Selection of unstable distal radius fractures in 300 patients, divided into operation group and plaster external fixation group with 150 cases in each, applied in the surgery group palm side approach, open reduction and plate screw fixation in the treatment, plaster external group was fixed with plaster external fixation, compared two groups of patients after clinical effect. Results The excellent rate of operation group was 90.7%, the excellent and good rate of plaster external fixation group was 72.7%, the difference was significant between two groups (P<0.05). Conclusion Compared with the plaster external fixation, surgical treatment of unstable distal radius fractures of the clinical effect is more significant, it is worth promoting.
