①目的探讨ＣＴ检查对髋关节病变的价值和适应证。②方法回顾性阅读８２例髋关节病变病人的ＣＴ扫描片和Ｘ线平片，逐一记录关节不同部位的异常情况并行统计学处理。③结果ＣＴ和Ｘ线平片显示有关节囊及周围软组织异常者分别为５６和１１个关节，前后部关节间隙异常者分别为３６和０个关节，前后部骨性关节面异常者分别为３８和０个关节；关节内游离体显示数目分别为３５和１２枚；邻关节骨内病灶显示数目分别为９８和５３个，其中大小、位置及边界明确者分别为９３和１３个，可确定内部成分（气体、液体、软组织、钙化和骨化）者分别为９０和７个。④结论与Ｘ线平片相比，ＣＴ在显示髋关节囊及周围软组织，关节前后部间隙和关节面，关节内游离体和邻关节骨内病灶方面有明显优势。因此，对临床和Ｘ线平片可疑髋关节肿胀、肿物、关节内游离体，邻关节骨内病灶，化脓性髋关节炎和股骨头缺血坏死或上述病变难以确定部位、范围和程度而需决定治疗方案者，应采用ＣＴ检查。
① Objective To investigate the value and indications of CT examination on hip joint disease. Methods A retrospective review of 82 cases of hip joint disease in patients with CT scan and plain radiographs, one by one record of different parts of the joint abnormalities and statistical analysis. Results CT and X-ray showed that there were 56 and 11 joints with joint capsule and surrounding soft tissue abnormalities respectively. There were 36 and 0 joint anomalies in the anterior and posterior parts respectively, and the anterior and posterior bony joint areas were 38 And 0 joints. The number of free bodies in joints was 35 and 12, respectively. The number of lesions in adjacent joints was 98 and 53, respectively. The size, location and boundary were 93 and 13, respectively, The components (gas, liquid, soft tissue, calcification and ossification) were 90 and 7, respectively. ④ Conclusion Compared with plain radiography, CT has obvious advantages in displaying the hip capsule and its surrounding soft tissue, the anterior and posterior joint space and the articular surface, the intra-articular free body and the adjacent joint bone. Therefore, it is difficult to determine the location, extent and degree of suspicious hip swollenness, tumor, intra-articular complex, intra-articular osteoarthritis, septic hip arthritis and avascular necrosis of the femoral head in clinical and X-ray films Need to decide the treatment plan, should be used CT examination.
