Twenty-six patients (30 hips) who had acetabular dysplasia were operated on by circumferential acetabular medial wall displacement osteotomy to reconstruct the acetabulum during total hip arthroplasty. All patients had cementless acetabular components implanted. The average acetabular component size was 50 mm (range, 44-56 mm). Only 2 hips needed structural bone graft. The mean follow-up period was 22 months (range, 6-32 months). Harris hip score had changed from 47.31 (range, 19-69 points) to 94.69 (range, 85-100 points) postoperatively (P < .01). Using the Ranawat acetabular triangle to determine the optimal hip center of rotation, the postoperative hip biomechanical environment had been improved. Our short-term follow-up suggests this technique is reliable and reproducible and generally avoids the use of bone graft and graft site morbidity. In addition, it allows the use of standard modular cementless components in patients with acetabular dysplasia.
26例（30髋）髋臼发育不良患者在全髋关节置换术中接受了髋臼内侧壁环形移位截骨术以重建髋臼。所有患者均植入了非骨水泥髋臼假体。髋臼假体的平均尺寸为50mm（范围44 - 56mm）。仅2髋需要结构性骨移植。平均随访时间为22个月（范围6 - 32个月）。术后Harris髋关节评分从术前的47.31分（范围19 - 69分）提高到94.69分（范围85 - 100分）（P <.01）。使用Ranawat髋臼三角来确定最佳髋关节旋转中心，术后髋关节生物力学环境得到改善。我们的短期随访表明，该技术可靠且可重复，通常可避免使用骨移植及移植部位的并发症。此外，它允许在髋臼发育不良患者中使用标准模块化非骨水泥假体。
