Successful total hip arthroplasty (THA) in congenital dislocated hips demands anatomical reduction in the normal center of rotation without overstretching the sciatic nerve and without excessive compression or abnormal forces across the joint. Proximal femoral and subtrochanteric shortening osteotomy has been described for THA for the treatment of dislocated hips. However, these osteotomies are demanding, associated with deformation of femoral canal and nonunion, and may increase the femoral stem stress. This study reports excellent results in 24 patients with a new surgical technique that combines THA with a distal femoral shortening in severely deformed hips using customized components.
先天性髋关节脱位患者成功实施全髋关节置换术（THA）需要在正常旋转中心进行解剖复位，同时不牵拉坐骨神经，不产生关节过度受压或异常受力。近端股骨和转子下缩短截骨术已被用于THA治疗髋关节脱位。然而，这些截骨术要求高，会导致股骨髓腔变形和骨不连，并可能增加股骨干应力。本研究报告了采用一种新手术技术治疗24例严重畸形髋关节患者的优异结果，该技术将THA与使用定制组件的股骨远端缩短术相结合。
