Computed tomography (CT) scanning is a useful tool in many areas of orthopedics. This prospective study reviews the authors' experience with CT scans in 73 patients studied prior to total hip arthroplasty. The CT scan is valuable in the primary total hip arthroplasty if the radiograph suggests medial, posterior, or superior acetabular wall defects. In some instances, bone grafting or other special procedures are required for the reconstruction of these defects. In the present study, preoperative CT identified an abnormality in 18 cases with deficient acetabular walls, while plain radiographs identified only six of these difficulties. Although important information for planning revision total hip arthroplasties was noted in this series, CT scans are indicated primarily in instances of suspected acetabular wall defects.
计算机断层扫描（CT）在骨科的许多领域都是一种有用的工具。这项前瞻性研究回顾了作者对73例全髋关节置换术前接受CT扫描患者的经验。如果X线片提示髋臼内侧、后侧或上壁有缺损，CT扫描在初次全髋关节置换术中很有价值。在某些情况下，重建这些缺损需要植骨或其他特殊手术。在本研究中，术前CT在18例髋臼壁缺损病例中发现了异常，而普通X线片仅发现了其中6例。尽管本系列研究中注意到了对计划翻修全髋关节置换术有重要意义的信息，但CT扫描主要适用于怀疑髋臼壁缺损的情况。
