The purposes of this study were to evaluate the midterm clinical and radiographic results of total hip arthroplasty (THA) in patients with Crowe type IV developmental dysplasia and to evaluate whether low back pain would improve after THA. Eighteen consecutive patients (20 hips) were included in this study. The average age at the time of surgery was 58.5 years. The average follow-up was 10.2 years. The socket was placed at the level of the true acetabulum, and a femoral shortening osteotomy was performed. The average Harris hip score before surgery was improved from 56 to 85 points at the final follow-up. Revision was performed in 4 hips due to loosening of the femoral component in 1 hip and osteolysis in 3 hips. The midterm outcomes of THA in patients with Crowe type IV developmental dysplasia were satisfactory. The severity of low back pain was significantly reduced after THA.
本研究旨在评估 Crowe Ⅳ型发育性髋关节发育不良患者全髋关节置换术（THA）的中期临床和影像学结果，并评估 THA 后腰痛是否会改善。本研究纳入了 18 例连续患者（20 髋）。手术时的平均年龄为 58.5 岁。平均随访 10.2 年。髋臼杯置于真髋臼水平，行股骨短缩截骨术。术前 Harris 髋关节评分平均为 56 分，末次随访时提高至 85 分。4 髋因 1 髋股骨假体松动和 3 髋骨溶解而翻修。Crowe Ⅳ型发育性髋关节发育不良患者 THA 的中期结果令人满意。THA 后腰痛的严重程度显著减轻。
