This study was conducted to evaluate the clinical and radiographic results of 22 total hip replacements done in 17 consecutive patients for coxarthrosis due to developmental dysplasia or dislocation of the hip. All operations were done using an anterior approach without trochanteric osteotomy. Standard cementless prostheses were used in all cases. There was no custom-designed prosthesis used. The acetabular cup was placed in an anatomic position in the true acetabulum in every case. Bulk autograft was necessary to reconstruct the deficient acetabular roof in only 2 hips. The average follow-up was 63 months (range, 40 months to 95 months). The average Harris Hip Score was improved from a preoperative value of 35 (range, 24 to 46), to 96 (range, 79 to 100) at final follow-up. To date, no revision has been done. Three hips showed radiographic evidence suggestive of aseptic loosening (2 stems and 1 cup), but the clinical results remain satisfactory. There is no incidence of dislocation, sciatic nerve palsy, or infection.
本研究旨在评估17例因发育性髋关节发育不良或髋关节脱位导致髋关节骨关节炎的患者连续进行的22例全髋关节置换术的临床和影像学结果。所有手术均采用前方入路，未进行转子截骨。所有病例均使用标准非骨水泥假体。未使用定制假体。在每一病例中，髋臼杯均放置于真髋臼的解剖位置。仅2例髋关节需要大块自体骨移植来重建髋臼顶缺损。平均随访时间为63个月（范围40个月至95个月）。最终随访时，Harris髋关节平均评分从术前的35分（范围24至46分）提高到96分（范围79至100分）。迄今为止，尚未进行翻修手术。3例髋关节有影像学证据提示无菌性松动（2个股骨柄和1个髋臼杯），但临床结果仍令人满意。未发生脱位、坐骨神经麻痹或感染。
