外固定架治疗桡骨远端粉碎性骨折的疗效分析

目的探讨外固定架治疗桡骨远端粉碎性骨折的临床疗效。方法 2007年11月—2012年5月共收治的骨折患者22例(骨折23例次)。AO/ASIF分型包括C1型9例、C2型12例和C3型2例。桡骨克氏针固定10例,螺钉固定1例;临近尺骨下段骨折钢板内固定术1例。结果术后随访4~40个月。术前尺偏角为-5°~10°,掌倾角为-20°~20°;术后尺偏角为10°~25°,掌倾角为8°~17°。腕关节疗效按Dienst功能标准评定:优15例,良6例,优良率为91.3%(21/23)。结论外固定架治疗桡骨远端粉碎性骨折,术中有限开放复位、克氏针或螺钉固定获得良好复位和增加外固定架的稳定性,可以最大限度地恢复腕关节功能。

Efficacy analysis of external fixation on distal radial comminuted fractures

Objective To explore the clinical efficacy of external fixation of distal radius comminuted fractures.Methods The treatment contained 22 patients with 23 fractures from November 2007 to May 2012,including 9 cases of AO/ASIF classification type C1,12 cases of C2,and 2 cases of C3.There were ten cases of radial kirschner wire fixation,1 case of screw fixation,and 1 case of near ulna fracture plate internal fixation.Results The patients were followed up from 4 to 40 months after surgery.Before ulnar deviation was-5-10°,the palm inclination was-20 to 20°,postoperative ulnar deviation was 10 to 25° and the palmar angle was 8 to 17°.Wrist efficacy was assessed by dienst functional standard: excellent in 15 cases,good in 6 cases,good rate of 91.3%(21/23).Conclusion External fixation of distal radius fracture,surgery limited open reduction and kirschner wires or screw fixations get a good reset and increase the stability of the external fixator,which can maximize the recovery of wrist function.
