钢板预置关节镜复位技术(PART)治疗桡骨远端骨折

目的 研究使用钢板预置关节镜复位技术(PART)治疗桡骨远端骨折,将腕掌侧锁定钢板技术与腕关节镜有效结合,提高C型桡骨远端骨折(AO分型)的治疗效果.方法 自2009年2月～2011年7月使用PART技术对13例桡骨远端C型骨折进行手术治疗,行桡骨远端骨折切开复位后予克氏针及预置掌侧锁定钢板临时固定骨折,在腕关节镜下对关节面处骨折行进一步复位,满意后用钢板螺钉将骨折完全固定.结果 桡骨远端关节面台阶移位及水平移位均在2 mm内.掌倾角0～15°,平均13.4°,尺偏角17～26°,平均22.3°.桡骨远端高度无短缩.采用Gartland和Werley评分标准对腕关节功能进行评价:优8例,良4例,中1例.结论 PART技术治疗桡骨远端C型骨折,将腕掌侧锁定钢板技术与腕关节镜有效简便结合,提高了关节面骨折复位水平,骨折固定坚强,可早期进行腕关节功能锻炼,临床效果优异.

Plate presetting arthroscopic reduction technique for fractures of distal radius

Objective To study the plate presetting arthroscopic reduction technique(PART) for the distal radius fractures and improve the C type(AO) fracture therapeutic efficacy,with the palm locking plate and arthroscopy.Methods From February 2009 to July 2011,PART techniques were used for 13 C type fracture cases.Arthroscopy was used to check the reduction of the articular fracture after open reduction with the temporary fixation of the plate and K wire.The final fixation was finished after the check.Results The displacement of the articular fracture was below 2 mm.The angle of inclination was between 0°to 15°,and the average angle was 13.4°.The ulnar deviation angle was from17°to 26°,and the average angle was 22.3°.There was no crispation of radius.The wrist function with Gartland and Werley standard was estimated.,8 cases were excellent,4 cases good and 1case normal.Conclusion PART technique can combine the palm plate and arthroscopy efficiently,make strong fixation to allow early exercise,and the therapy result is excellent.
