CT与X线诊断老年股骨头坏死临床对比分析

Clinical Comparative Analysis of CT and X-ray Diagnosis of Senile Femoral Head Necrosis

目的:探讨并比较CT与X线诊断老年股骨头坏死临床价值。方法:回顾性分析临床确诊为股骨头坏死老年患者76例CT及X线影像学资料,比较患者股骨头总检出率及各临床分期检出率。结果:CT股骨头坏死总检出率明显高于X线,组间比较差异有统计学意义(P<0.05);同时CTⅠ、Ⅱ期股骨头坏死检出率均明显高于X线,组间比较差异有统计学意义(P<0.05);但Ⅲ、Ⅳ及Ⅴ期股骨头坏死检出率两组间比较差异无统计学意义(P>0.05)。结论:CT诊断老年股骨头坏死临床检出率明显高于X线,且对于老年患者早期股骨头坏死病变更具诊断价值。

Objective：To investigate the clinical value and compare CT and X-ray diagnosis of senile femoral head necrosis. Meth- ods：A retrospective analysis of our hospital from January 2006-2011November were the clinical diagnosis of femoral head necrosis in elderly patients 76 cases of CT and X-ray imaging data to compare patients with femoral head total detection rate and clinical staging detected rate. Results： The CT osteonecrosis total detection rate was significantly higher than the X-ray, the difference between groups was statistically significant （P〈0.05） ; CT I and II of femoral head necrosis detection were significantly higher than the X- ray between the two groups the difference was statistically significant （P〈0.05） . III, IV and V of the femoral head necrosis detec- tion rate between the two groups the difference was not statistically significant （P〈0.05）. Conclusion. CT diagnosis of senile femoral head necrosis clinical detection rate was significantly higher than the X-ray, and more diagnostic value of early femoral head nec- rosis lesions in elderly patients.
