MRI对股骨头缺血性坏死诊断价值及行介入治疗后的效果评估OA
Diagnostic Value of MRI in Avascular Necrosis of the Femoral Head and Evalution of Effect after Interventional Therapy
目的:探讨核磁共振成像(MRI)对股骨头缺血性坏死(ANFH)诊断价值及行介入治疗后的效果评价.方法:选取 2017年 8月—2022年 9月于解放军第 970医院住院诊治的 78例ANFH患者为研究对象,所有患者都给予介入治疗,判定预后疗效.所有患者在治疗前后都给予核磁共振成像检查,记录征象特征并给予相关性分析.结果:78例患者经过治疗后,疗效判断为优 50例,良 20例,差 8例,优良率为 89.74%,即优良组 70例,非优良组 8例.优良组的发病原因、体重指数、发病位置、临床分期、病程、性别、年龄等与非优良组对比,组间差异无统计学意义(P>0.05).非优良组的骨髓水肿、关节腔积液、线样征、斑片征等常规核磁共振成像征象为100.00%、87.50%、100.00%、75.00%,均高于优良组的31.43%、30.00%、25.71%、21.43%,组间差异有统计学意义(P<0.05).非优良组的坐骨股骨间隙高于优良组,股方肌间隙低于优良组,组间差异有统计学意义(P<0.05).在 78例患者中,Spearman分析显示疗效优良率与骨髓水肿、关节腔积液、线样征、斑片征、坐骨股骨间隙、股方肌间隙等都存在相关性(P<0.05).结论:ANFH患者在核磁共振成像中多伴随有多种征象异常,介入治疗的预后疗效相对比较好,核磁共振成像对股骨头缺血性坏死诊断价值及行介入治疗后疗效评估具有很好的价值.
Objective:To investigate the value of magnetic resonance imaging(MRI)in the diagnosis of avascular necrosis of the femoral head(ANFH)and the evaluation of therapeutic effect after interventional therapy.Methods:78 patients with ANFH who were hospitalized and treated in the 970th Hospital of PLA from August 2017 to September 2022 were selected as the research objects.All patients were treated with interventional therapy,and the prognosis and efficacy were determined.All patients underwent magnetic resonance imaging examination before and after treatment.The signs were recorded and the correlation analysis were performed.Results:After treatment,the efficacy of 78 patients was judged as excellent in 50 cases,good in 20 cases,and poor in 8 cases,with an excellent and good rate of 89.74%,including 70 cases in the excellent group and 8 cases in the non-excellent group.There were no significant differences in the etiology,body mass index,location of disease,clinical stage,course of disease,gender and age between the excellent and excellent group(P>0.05).The conventional MRI signs such as bone marrow edema,joint cavity effusion,line sign,and patchy sign in the non-excellent group were 100.00%,87.50%,100.00%,and 75.00%,which were higher than 31.43%,30.00%,25.71%,and 21.43%in the excellent group,and the differences between the two groups were statistically significant(P<0.05).The ischiofemoral gap of the non-excellent group was higher than that of the excellent group,and the quadratus femoris gap was lower than that of the excellent group,and the differences between the two groups were statistically significant(P<0.05).In 78 patients,Spearman analysis showed that the excellent and good efficacy rate was correlated with bone marrow edema,joint cavity effusion,linear sign,patchy sign,ischiofemoral space,and quadratus femoris space(P<0.05).Conclusion:Patients with ANFH are often accompanied by a variety of abnormal signs on MRI,and the prognosis of interventional treatment is relatively good.Mri has a good value in the diagnosis of avascular necrosis of the femoral head and the evaluation of the efficacy of interventional treatment.
