锁定加压接骨板治疗全膝关节置换术后Rorabeck Ⅰ-Ⅱ型股骨髁上假体周围骨折的疗效

Treatment of Rorabeck Ⅰ-Ⅱ femoral supracondylar periprosthetic fractures after total knee arthroplasty with locking compression plate

目的探讨采用锁定加压接骨板治疗全膝关节置换术后Rorabeck Ⅰ-Ⅱ型股骨髁上假体周围骨折的临床效果。方法研究纳入2014年3月~2016年3月间,我科收治的全膝关节置换术后Rorabeck Ⅰ-Ⅱ型股骨髁上假体周围骨折患者10例,其中男4例,女6例,平均年龄68岁(62~78岁),采用切开复位股骨远端锁定加压接骨板固定,对患者术后的膝关节活动度关节功能等进行评定。结果随访时间4~28个月,平均随访13个月,10例患者骨折均愈合。X线片显示假体稳定,无松动表现。术后膝关节活动度平均为0~950,膝关节HSS评分为80.5分。结论锁定加压接骨板内固定术是治疗全膝关节置换术后Rorabeck Ⅰ-Ⅱ型股骨髁上假体周围骨折的有效的方法,临床效果满意。

Objective To investigate the clinical results of therapy of Rorabeck Ⅰ-Ⅱ femoral supracondylar periprosthetic fractures after total knee arthroplasty （TKA） with open reduction and internal fixation （ORIF） using lockng compression plate （LCP）. Methods＂ Ten eases ofRorabezk Ⅰ-Ⅱ femoral supraeondylar periprosthetie fractures after TKA were Ixeated using LCP in our department ficom March 2014 to March 2016.4 males and 6 females, average age 68 years （62-78 years）, Using open reduction and chstal temoral locking compression plato nxauon, Tne joint runcuon ot me paucms was eyaluated.Results They had full follow-up for 4 to 28 months （mean 13 months）. 10 patients with fractures healed.X-ray showed the prosthesis stable, no loose performance None of the fractured patients had any infection or internal-fixation failure. The average knee motion range was 0-95. The knee average HSS score was 80.5 points. Conclusion Locking compression plate internal fixation is a one of the valuable treatments for Rorabeck Ⅰ-Ⅱ femoral supracondylar periprosthetic fractures after total knee arthroplasty, Clinical results were satisfactory.
