High developmental dysplasia of the hip is commonly treated with total hip arthroplasty and shortening osteotomy. We present a two stage technique, consisting of progressive femoral lowering followed by total hip arthroplasty. The clinico-radiographic results of eleven patients (twelve hips) who were operated on with the two-stage technique were evaluated at a mean follow-up of 11 ± 5 years. At the final follow-up, ten patients (eleven hips) had a mean Harris hip score of 85 ± 5 points with no implant loosening. One patient (one hip) was revised at 5 years due to infection. No neurovascular complications were observed in any patients. With this technique, we could place the cup in the anatomical position and obtain complete limb symmetry with excellent clinical results at long-term.
重度发育性髋关节发育不良通常采用全髋关节置换术和短缩截骨术治疗。我们提出一种两阶段技术，包括逐步降低股骨，随后进行全髋关节置换术。对采用该两阶段技术进行手术的11例患者（12髋）进行了临床影像学结果评估，平均随访时间为11±5年。在末次随访时，10例患者（11髋）的Harris髋关节评分平均为85±5分，无植入物松动。1例患者（1髋）在5年时因感染进行了翻修。所有患者均未观察到神经血管并发症。采用该技术，我们能够将髋臼杯置于解剖位置，并在长期随访中获得完全的肢体对称和优异的临床效果。
