【摘要】：背景:坐骨股骨撞击综合征越来越引起人们的重视,但因其发病率较低,国内外相关研究较少,部分影像科医生对该病的影像学表现认识不够深刻。目的:探讨坐骨股骨撞击综合征的MRI诊断标准,以提高对坐骨股骨撞击综合征MRI表现的认识。方法:选择拟诊断为坐骨股骨撞击综合征的病例16例21髋作为病例组,25例健康志愿者作为对照组,在MRI轴位像上分别测量双侧坐骨股骨间距(即坐骨结节与股骨小转子间的最短距离)与股方肌间距(股骨小转子与乆绳肌腱止点的距离),并观察股方肌的信号及形态。对比分析2组坐骨股骨间隙和股方肌间隙的差异。结果与结论:(1)16例患者中女13例,男3例;双髋发病5例,均为女性;(2)病例组患侧坐骨股骨间距为(13.65±3.87)mm,对侧为(22.17±5.75)mm,差异有显著性意义(P0.01);患侧股方肌间距为(7.15±3.50)mm,对侧为(12.89±3.13)mm,差异有显著性意义(P0.01);(3)对照组左侧坐骨股骨间距为(23.59±6.14)mm,右侧为(23.08±5.82)mm,双侧对比差异无显著性意义(P0.05);对照组左侧股方肌间距为(12.41±3.75)mm,右侧为(13.22±3.84)mm,双侧对比差异无显著性意义(P0.05);(4)病例组患侧坐骨股骨间距、股方肌间距与对照组比较差异有显著性意义(P0.01),病例组对侧坐骨股骨间距、股方肌间隙与对照组比较差异无显著性意义(P0.05);(5)病例组股方肌有不同程度变形、水肿及萎缩;(6)综上,女性坐骨股骨撞击综合征的发病率明显高于男性,双侧发病常见。患侧坐骨股骨间距≤11.46 mm,股方肌间距≤5.53 mm,患侧股方肌水肿和形态异常,为坐骨股骨撞击综合征的MRI诊断标准。MRI轴位压脂图像是诊断坐骨股骨撞击综合征的敏感序列。
[Abstract]:Background: more and more attention has been paid to the sciatic femur impingement syndrome, but because of its low incidence and few related studies at home and abroad, some imaging doctors do not have a deep understanding of the imaging manifestations of the disease. Objective: to investigate the diagnostic criteria of MRI in sciatic femur impingement syndrome (IHS) in order to improve the recognition of MRI manifestations of ischium femur impingement syndrome (IHS). Methods: 16 cases (21 hips) of sciatic femur impingement syndrome were selected as the control group, 25 healthy volunteers were selected as the control group. The distance between the bilateral sciatic femur (the shortest distance between the ischium and the femoral trochanter) and the quadratus femoris (the distance between the trochanter of the femur and the insertion point of the rope tendon) were measured on the MRI axial images, and the signal and morphology of the quadratus femoris were observed. The difference of femoral space and quadratus femoris space between the two groups was compared and analyzed. Results and conclusion among the 16 cases, 13 cases were female, 3 cases were male, 5 cases were double hip disease, The distance between the sciatic femur of the affected side and the contralateral side was 13.65 卤3.87 mm and 22.17 卤5.75 mm respectively, the difference was significant (P 0.01), the distance of the quadratus femoris was 7.15 卤3.50 mm, the contralateral side was 12.89 卤3.13 mm, the difference was significant (P 0.01). The distance between the left side and the right side of the control group was 23.59 卤6.14 mm and 23.08 卤5.82 mm, respectively. There was no significant difference in bilateral contrast (P 0.05), while in the control group, the distance between the left quadratus femoris was 12.41 卤3.75 mm, the right side was 13.22 卤3.84 mm, and the bilateral contrast had no significant difference (P 0.05). The distance of quadratus femoris was significantly different from that of the control group (P 0.01). The distance of the contralateral ischium femur and the space between the quadratus femoris and the control group were not significantly different from those of the control group (P 0.05). The quadratus femoris of the case group had different deformations, edema and atrophy. The incidence of femur impingement syndrome in female is higher than that in male, and bilateral incidence is common. The distance between the affected femur and quadratus femoris was less than 11.46 mm and 5.53 mm, respectively. The edema and morphological abnormality of the affected side of the quadratus femoris were the diagnostic criteria of the sciatic femur impingement syndrome. The axial compression fat image was a sensitive sequence for the diagnosis of the sciatic femur impingement syndrome.
