目的探讨髋关节发育不良继发骨性关节炎全髋关节置换术后髋臼软骨下骨囊肿的形态变化。方法回顾分析208例初次非骨水泥型全髋关节置换术患者261例的临床资料。通过CT观察软骨下骨囊肿的形态变化。比较术后3个月和7~10年(平均8.4年)CT扫描的平均截面积。结果术前CT发现髋臼下软骨下骨囊肿占49.0%。术后7~10年CT扫描未发现新发现的囊性病变。结论发育性髋关节发育不良患者髋臼软骨下骨囊肿在全髋关节置换术后并没有增大或扩大，提示发育性髋关节发育不良患者髋臼骨囊肿纵向形态的改变不影响全髋关节置换术的远期内固定。
PurposeThe purpose of this study is to clarify morphological changes of acetabular subchondral bone cyst after total hip arthroplasty for osteoarthritis secondary to developmental dysplasia of the hip.MethodsTwo hundred and sixty-one primary cementless total hip arthroplasties of 208 patients, 18 males, 190 females, were retrospectively reviewed. Morphological changes of subchondral bone cyst were evaluated by computed tomography (CT). The mean cross-sectional area of the cyst from CT scans at 3 months postoperatively and after 7–10 years (average 8.4 years) were compared.ResultsAcetabular subchondral bone cysts were found in 49.0% of all cases in preoperative CT scans. There was no cyst which was newly recognized in CT scan performed after postoperative 7–10 years. All the cross-sectional areas of the cysts evaluated in this study were reduced postoperatively.ConclusionsThis study revealed that acetabular subchondral bone cysts do not increase or expand after total hip arthroplasty and indicated that the longitudinal morphological change of acetabular bone cysts in patients of developmental dysplasia of the hip do not influence long-term implant fixation in total hip arthroplasty.
