分叉钢板和拉力螺钉治疗髋臼后壁骨折疗效比较分析

Efficacy of fracture treatment of acetabular posterior wall by lag screw and spike plate

目的探讨采用分叉钢板和拉力螺钉治疗髋臼后壁骨折临床疗效。方法回顾性分析我院骨科2006年7月至2013年10月收治的髋臼后壁骨折患者87例,其中49例采用分叉钢板治疗的患者为观察组,38例采用拉力螺钉治疗的患者为对照组。通过术后matta评分结果及并发症的比较评定两组的疗效。结果观察组内固定优良率为72.91%,对照组优良率为94.73%,两组差异有统计学意义(χ2=7.82,P<0.05);观察组并发症发生率为33.34%,对照组为13.15%,差异有统计学意义(χ2=6.76,P<0.05)。结论采用拉力螺钉的固定效果好且并发症少,有较高的临床推广价值。

Objective To evaluate the efficacy of fracture of the acetabular posterior wall treated by lag screw and spike plate .Methods 87 patients with fracture of the acetabular posterior wall admitted in our hospital from July 2006 to November 2013 were selected and 49 patients were treated by spike plate as the observer group , 38 patients were treated by lag screw as the control group .Internal fixation effect was evaluated according to matta score .Results The total rate of excellence and goodness in observer group and control group was 72.91% and 94.73%, there was statistical difference （χ2 =7.82, P 〈0.05 ）;Complication rates were 33.34%and 13.15%, respectively, there was statistical difference （χ2 =6.76,P〈0.05）.Conclusions Lag screw is much better and is an effective method to treat fracture of the acetabular posterior , and it is worthy of popularization and application in grassroots hospital .
