Objective To investigate the effect of anatomical plate internal fixation with dorsal metacarpal approach in the treatment of distal radius fracture. Methods The clinical data of C3 type distal radius fracture treated with surgery from January 2014 to June 2017 were analyzed retrospectively. Results 36 cases were included in the comparison suggested 3 months X-ray preoperative and postoperative volar tilt by preoperative -15(SD=5)was corrected for the postoperative 13 degrees (SD=4) (P<0.05),ulnar deviation from preoperative 11 degrees(SD=4) corrected for postoperative 22 degrees (SD=3)(P<0.05);wrist flexion from preoperative 42 degrees (SD=12) to postoperative 51 degrees(SD=14) (P<0.01); radial shortening the length of the preoperative 12mm (SD=3.8)correction after 2mm (SD=1.2);the grip from the preoperative contralateral 35％ (SD=4.3)to resume operation after the contralateral 80％ (SD=5.2);the functional score was increased from 12 preoperatively (SD=3.8) to 18 (SD=4.9)postoperatively. Conclusion Volar dorsal approach combined with locking anatomical plate fixation is an effective fixation for comminuted distal radius fractures.%目的 探讨掌背侧入路锁定解剖钢板内固定治疗桡骨远端骨折的疗效.方法 回顾性分析2014年1月至2017年6月接受手术治疗的C3型桡骨远端骨折病例临床资料.结果 共纳入36例病例,术前以及术后3个月X线片比较提示,掌倾角由术前-15°(SD=5)°纠正为术后13°(SD=±4)(P<0.05),尺偏角由术前11°(SD=4)纠正为术后22°(SD=3)(P<0.05);腕关节屈曲活动度从术前42°(SD=12)恢复至术后51°(SD=14)(P<0.01);桡骨短缩长度由术前12mm(SD=3.8)纠正为术后2mm(SD=1.2);握力从术前健侧的35％(SD=4.3)恢复至术后健侧的80％(SD=5.2).功能评分由术前12分(SD=3.8)增加至术后18分(SD=4.9).结论 掌背侧入路联合锁定解剖钢板内固定治疗粉碎性桡骨远端骨折是一种有效的固定方法.
