Abstract: 【Abstract】 Objective To analyze the clinical effect of the treatment of osteoporotic distal radius fractures with the locking compression plate fixation and plaster immobilization. Methods 103 cases of osteoporotic distal radius fractures were recruited from June 2013 to June 2014 and assigned to two groups, observation group（n=52）and control group（n=51）. The patients in control group were treated with closed reduction and cast immobilization, and those in observation group were given locked volar plate and screws fixation. The wrist-hand functional improvement and fracture healing were observed in one year after treatment in two groups. Results The total effective rates of observation group and control group were 96.15% and 80.39%, having significant difference （P<0.05）. The back strength, cock waist, radial deviation, forearm rotation angle in observation were ameliorated much better than that in control group（P<0.05）. Conclusion The surgical procedure of palm side locking plate has more advan-tage of the closed reduce for intra-articular fractures of the distal radius combined with osteoporosis.

摘要： 【摘要】目的分析掌侧锁定钢板与石膏制动治疗骨质疏松性桡骨远端关节内骨折的临床疗效。方法选择濮阳市人民医院2013年6月~2014年6月期间103例骨质疏松性桡骨远端关节内骨折患者进行分组，对照组51例给予手法复位后石膏制动治疗，观察组52例给予掌侧锁定钢板治疗，观察两组患者1年后改善腕关节功能及骨折愈合情况的对比。结果观察组术后总有效率96.15%高于对照组80.39%（P<0.05）；观察组1年后回访关节指标背伸活动度、掌屈活动度、桡偏角度、前臂旋前角度、前臂旋后角度改善情况均优于对照组（P<0.05）。结论掌侧锁定钢板能够通过减小对软组织的刺激、增强关节的稳定性以减轻骨质疏松性桡骨远端关节内骨折患者的疼痛，改善腕关节功能，效果确切。
