摘　　要：目的探讨坐骨股骨撞击综合征的MRI征象及诊断效能。方法回顾性分析我院临床诊断为坐骨股骨撞击综合征髋关节58例(病例组)共70个髋关节,以同时期来我院体检的70个髋关节MR作为对照组,测量两组人群坐骨股骨间隙(IFS)、股方肌间隙(QFS)并分析其差异,比较两组股方肌形态及信号差异。结果病例组IFS、QFS分别为(11.94±0.83)mm、(5.07±1.42)mm,均小于对照组,差异有统计学意义(P<0.05);病例组与正常组IFS与QFS均呈线性正相关,相关系数r分别为0.47、0.68(P值均<0.001);ROC分析显示IFS、QFS、股方肌四个影像征象(包括股方肌变形、水肿、萎缩、脂肪浸润)诊断坐骨股骨撞击综合征的曲线下面积(AUC)分别为0.65至1.00(95%CI:0.56~0.74,0.99~1.00)。结论MRI上IFS、QFS变窄可用于诊断坐骨股骨撞击综合征,股方肌变形、水肿、萎缩、脂肪浸润可提示诊断本病。ObjectiveTo investigate the MRI manifestations and diagnostic efficacy of ischiofemoral impingement(IFI)syndrome.Materials andMethodsMR data of 70 hip joints from 58 cases of IFI which diagnosed by clinical physicians were included in the study.A total of 70 hip joint from 45 patients who received physical examination in our hospital during the same period were collected as control group.The ischiofemoral space,quadratus femoris space were measured and the differences were compared,and the morphological and signal intensity differences of quadratus femoris were compared between the two groups.ResultsThe IFs and QFs of the IFI group were(11.94±0.83)mm and(5.07±1.42)mm respectively,which were lower than those of the control group(20.23±1.96)mm and(12.58±2.56)mm,the difference was statistically significant(P<0.05).IFs and QFs correlated positively in both IFI group and control group with correlation coefficient of 0.47 and 0.68,respectively(both of P values<0.001).ROC analysis showed that the area under curve(AUC)of IFs,QFs and quadratus femoris manifestation(including quadratus femoris deformation,edema,atrophy and fat infiltration)for the diagnosis of IFI were 0.65 to 1.00(95%CI:0.56~0.74,0.99~1.00).ConclusionThe narrowing of IFs and QFs on MRI can be used to diagnose the IFI,and the deformation,edema,atrophy and fat infiltration of quadrate femoris muscle help to the diagnosis of IFI.
