X线、CT联合骨密度测量在股骨头无菌坏死中的临床应用

摘要

目的：探讨X线、CT结合骨密度测量对股骨头无菌坏死(FHN)的程度及治疗效果的评估价值.方法：对32例41个FHN在治疗前、后3个月进行髋关节X线平片检查、CT检查和股骨头的骨密度测量,比较FHN治疗前后的骨密度及影像学的变化.结果：41个坏死的股骨头由X线确诊病灶24个,由CT确诊病灶17个；异常股骨头的骨密度值(BMD)和骨矿含量(BMC)与正常股骨头对比差异明显(P <0.05),FHN治疗前后BMD及BMC比较差异显著(P <0.05).结论：运用X线、CT联合骨密度仪测量骨密度值对FHN的程度及治疗效果具有较好的评估价值.%　　Objective: To explore the evaluate value of the degree of femoral head necrosis (FHN) and the treatment effect by X-ray,CT and bone density measurement. Methods: 32 cases with 41 FHN were examined by X-ray,CT and bone density measurement before and after 3 months treatment. The changes of the bone density and imaging of the FHN were compared. Results: 24 FHN were seen on x-ray and 17 FHN were seen on CT. There were significantly different of bone mineral density (BMD) and bone mineral content (BMC) between the FHN and the normal femoral head, also the before and after treatment of FHN,both P < 0.05. Conclusion: There are better evaluate value of the degree and treatment effect of FHN by X-ray,CT combination with bone density measurement.
