背景资料：在发育性髋关节发育不良（DDH）患者的全髋关节置换术（THA）中，已采用内侧化技术在真实髋臼水平重建髋臼。了解髋臼内侧壁的骨量对制定最佳髋臼重建计划和避免并发症具有重要意义目的：应用CT评价DDH患者髋臼内侧壁的骨量及其与半脱位程度的关系。材料与方法：对21例DDH继发骨关节炎拟行全髋关节置换术患者的27个髋关节进行螺旋CT扫描。11例髋关节属于Crowe I类，16例髋关节属于Crowe II/III类。对原始CT数据进行滚动多平面重组（MPR）。结果：Crowe-I组和Crowe-II/III组髋臼内侧壁最小厚度分别为3.8 ± 2.1mm和7.1 ± 3.1mm，两组间差异有统计学意义（P
Background: The technique of medialization has been used to reconstruct acetabula at the level of true acetabula in total hip arthroplasty (THA) in patients with developmental dysplasia of the hip (DDH). Appreciation of the bone stock in the medial acetabular wall is significant for making an optimal acetabular reconstruction plan and avoiding complications.Purpose: To evaluate the bone stock of the medial acetabular wall and its relation to the degree of subluxation in patients with DDH using computed tomography (CT).Material and Methods: Helical CT scans of 27 hips were obtained from 21 patients with osteoarthritis secondary to DDH who were scheduled for total hip arthroplasty. Eleven hips belonged to Crowe class I, while 16 hips belonged to Crowe class II/III. The raw CT data were reprocessed in various planes by scrolling multiplanar reformation (MPR). Acetabular opening, depth, and medial bone stock, as indicated by the minimum thickness of the medial acetabular wall, were measured in the transverse reformed MPR plane.Results: The minimum thicknesses of the medial acetabular wall in Crowe-I and Crowe-II/III hips were 3.8+/-2.1 mm and 7.1+/-3.1 mm, respectively, with statistically significant differences between the groups (P
