摘　　要：目的明确股骨头坏死异体骨移植术后临床疗效与其囊变区手术前后的CT影像学表现,同时运用CT检查方法对临床效果做出相关的评价。方法选择30例病例,其中单髋病人22例,双髋病人8例,共38例髋关节。均为Ⅱ期或Ⅲ期的病人(参照Froberg〔1〕等1996年提出的6期分期标准),经CT检查后行钻孔减压植入重组合异种骨(BMP)治疗,以3个月为1个疗程,连续观察2个疗程,并分别在术后第3个月及第6个月进行CT检查,观察股骨头坏死病变区的CT值及囊变体积大小,并与术前做对比,判断CT在其治疗过程中的作用。结果在观察的38例髋关节中,治疗后6个月髋关节疼痛、生活能力、关节活动度、行走距离临床体征方面优于治疗前(P<0.05);在CT观察指标上,治疗后6个月病变区的CT值高于治疗前(P<0.05);治疗后6个月病变区囊变的体积小于治疗前(P<0.05),手术6个月后,有27例股骨头囊变区明显消失,取而代之的是局部骨质密度增高,并有骨小梁形成。结论CT检查能够良好的反应出治疗前后股骨头坏死囊变区的变化,为临床治疗提供有利的影像学诊断依据。Objective To study the clinical effect of allegraft in treatment of femoral head necrosis （FHN） and Its CT image of cystis degeneration, and make clinical assessment with CT. Methods 30 cases （38 joints with single joint 22 cases and both joints 8 cases） of such patient in stage 11 and m were detected with CT and treated with BMP. They were observed 2 courses （ 3 months as a course） with CT scan. The CT value, cystis degeneration size were compared before and after treatment. The assessment was taken of CT during treatment. Results The data of joint pain, mobility of joint, walking distance and life ability of 6 month after treatment were better than those before treatment. The CT value was higher than that before treatment and CD size was smaller with P 〈0.05. The CD area disappeared in 27 cases after 6 months with high density bone and bone trabecula. Conclusion The CT might reflect the changes of lesion before and after treatment of cystis degeneration of femoral joint and that might supply the diagnostic image for treatment.
