    摘要:

    [目的]介绍Ganz入路埋头螺钉固定股骨头骨折的手术技术和初步临床结果。[方法]2015年1月~2021年9月我院收治的随访时间大于6个月的10例股骨头骨折,所有患者采用Ganz入路埋头螺钉固定治疗,自大转子顶点后上方至股骨外侧肌后缘纵向截骨显露关节囊。沿股骨颈的长轴“Z”形切开关节囊,将股骨头向前外侧脱位;清理髋关节关节腔,复位股骨头骨块后用2~3 埋头螺钉固定;内旋复位股骨头,复位大转子截骨块后并用2枚皮质骨螺钉固定。[结果]所有患者均顺利完成手术,手术时间为139.5±30.5(100-195)min,术中出血量为310.0±213.2(100-700)mL。平均骨折愈合时间3.6个月(3-6个月)。术后6个月髋关节功能(Thompson-Epstein标准):优5 例,良4例,可1例。[结论] Ganz入路埋头螺钉固定股骨头骨折,可充分显露髋臼及股骨头,能直视下复位骨折端,并发症发生率较低,具有良好的疗效。

    Abstract:

    To introduce the surgical technique and preliminary clinical results of Herbert screw via Ganz approach for fixation of femoral head fracture. [Methods] Between Jaunary 2015 and September 2021, 10 patients with an average follow-up of more than 6 months underwent Herbert screw via Ganz approach for fixation of femoral head fracture. The operating method is using an osteotomy lengthways from the upper vertex of the greater trochanter to the Posterior edge of the lateral femoral muscle to revealing the joint capsule. Then cut open the joint capsule with the shape of "Z" along the long axis of the femoral neck, dislocate the femoral head to anterolateral side, debride the articular cavity of hip joint, reduce femoral neck fracture block with 2-3 Herbert screws, reduces the femoral head by internal rotation and restore bone block of greater trochanter with 2 cortical bone screws. [Results] All patients underwent successful operation with operation time of 139.5±30.5(100-195)min, blood loss of 310.0±213.2(100-700)ml. The patients got clinical fracture healing in 3.6 months (3-6 months). The hip function scored 6 months after surgery according to Epstein-Thompson classification with the following results: 5 cases had excellent results, 4 cases were rated as good,while 1 as fair. [Conclusion] Herbert screw via Ganz approach for fixation of femoral head fracture with low complication rate and good effect, can fully expose the acetabulum and femoral head, can reduce the fracture end under direct vision.
