摘要
目的分析早期成人股骨头缺血性坏死CT征象及临床价值。方法选取本院2010年10月-2013年10月疑似早期成人股骨头缺血性坏死的患者117例,均行X线检查和CT检查,后经手术证实早期成人股骨头缺血性坏死患者71例,比较两种检查方法的灵敏度、特异度、准确度,分析早期成人股骨头缺血性坏死的CT征象。结果在早期成人股骨头缺血性坏死的诊断中,CT检查的灵敏度(98.6%)、特异度(97.8%)、准确度(98.3%)均明显高于X线检查(85.9%)、(84.8%)、(85.5%),差异有统计学意义(p<0.05)。CT诊断出早期成人股骨头缺血性坏死患者45例:31例患者骨小梁的星芒结构明显增粗,出现了扭曲变形,可见斑片状高密度的硬化区,可伴有骨折疏松。14例患者出现了斑片状骨硬化,可见囊状透亮区,且骨小梁的星芒结构消失。结论 CT检查可清晰显示早期成人股骨头缺血性坏死的征象,具有较高的灵敏度、特异度、准确度,可为患者后续的治疗提供有效的科学依据。
Objective To analyze the clinical value and signs of CT in diagnosis of early avascular necrosis of femoral head in adult. Methods 117 suspected patients with early avascular necrosis of femoral head in adult were selected in hospital from October 2010 to October 2013,who accepted X-ray examination and CT examination. 71 patients with early avascular necrosis of femoral head in adult were confirmed by operation. The sensitivity;specificity;accuracy were compared between two inspection methods. Signs of CT in diagnosis of early avascular necrosis of femoral head in adult were analyzed. Results In the diagnosis of early avascular necrosis of femoral head in adult, sensitivity（98.6%）, specificity（97.8%）, and accuracy（98.3%） of CT examination were significantly higher than X-ray examination（85.9%）, （84.8%）, （85.5%）. Differences were statistically significant （P〈0.05）. A total of 45 patients with early avascular necrosis of femoral head in adult were diagnosed by CT examination, 31 patients showed star structure of trabecular bone obviously thickening and twist deformation,while patchy high density of hardened zone could be seen,who might be associated with osteoporosis.14 patiens showed patchy bone sclerosis while cystic hyalomere could be seen,who＇s star structure of trabecular bone disappeared. Conclusion CT in diagnosis of early avascular necrosis of femoral head in adult has high sensitivity, specificity, and accuracy. Signs of CT in diagnosis of early avascular necrosis of femoral head in adult are clear, which can provide scientific basis for follow-up treatment of patients.
