髋臼后壁骨折内固定术后影像学评价及临床效果观察

Observation of clinical effect on after internal fixation of acetabular posterior wall fracture imaging

目的：评价髋臼后壁骨折内固定术后影像学及临床效果。方法：男17例，女6例；年龄17～73岁，平均42岁；伴股骨头后脱位13例，坐骨神经损伤3例。按照Tile分型，A1—1型7例，A1—2型12例，A1—3型4例。结果：23例患者术后均获得随访，随访时间为6～36个月，平均21个月。用系列X片及CT判断骨折复位情况及接骨板螺钉位置：解剖复位19例，满意复位4例。固定骨折块的拉力螺钉及接骨板位置良好，无螺钉进入或干扰髋关节。用改良d’Aubigne和Postel髋关节评分评定临床。结果：优15例，良6例，可2例，优良率91％。结论：准确的复位和可靠的内固定是骨折获得满意疗效的前提。

Objective：To evaluate image after internal fixation of acetabular posterior wall fracture and its clinical effects. Methods： Male 17 cases, female, 6 ; 17 - 73 year of age, 42 years on average ; posterior dislocation of the femoral head with 13 cases, 3 cases of in- jury of the sciatic nerve. According to the Tile patterns, A1 - 1 ： 7 cases, A1 - 2 ： 12 cases, A1 - 3 ： 4 cases. Results：23 cases with post- operative follow - up had been made available, follow - up 6 - 36 months, an average of 21 months. To observe fracture reduction and plate screw location by X series tablets and CT： anatomic reduction of 19 cases, satisiactory reduction 4. Immobilize the lag screw and plate position block well, hip screw - free access or interference. With improved d＇Aubigne and Postel hip score evaluation of clinical re- sults： 15 cases, benign and 6 cases, 2 cases, excellent rate of 91%. Conclusion ：Accurate reduction and reliable internal fixation might be a prerequisite for satistactory efficacy of acetabular posterior wall fracture.
