PDFAbstract
Objective To analyze the CT and X-ray findings of femoral head necrosis, and to compare their application value in its clinical diagnosis. Methods Sixty-six patients with avascular necrosis of femoral head treated in our hospital from September 2011 to September 2015 were selected as the research objects. All underwent CT and X-ray examination. The imaging features of the two methods were summarized and the detection rates were compared. Results Sixty-six cases of MRI were diagnosed as 19 cases of stageⅠ, 26 cases of stage II, 13 cases of stage III and 8 cases of stage IV, in which 61 cases were accurately diagnosed by CT and the detection rate was 92.4% (61/66). 53 cases were accurately diagnosed by X-ray and the detection rate was 80.3% (53/66) (P<0.05). Conclusion Compared with X-ray, the application of CT in femoral head necrosis can clearly reflect ligament femoral head calcification, enlarged iliopsoas bursa, joint capsular swelling, muscle atrophy and other lesions through multi-level observation. It can improve the accuracy of diagnosis and the diagnostic value is higher.
