【摘要】：目的:探讨MRI诊断坐骨股骨撞击综合征(IFI)的价值。方法:将临床及MRI共同诊断坐骨股骨撞击综合征的患者作为IFI组,并分析其MRI图像特点。另选取34名无临床症状患者作为对照。测量两组坐骨股骨间隙(IFS)及股方肌间隙(QFS)。利用独立样本t检验分析两组IFS及QFS的差异,并用ROC确定IFS及QFS诊断界值。采用单因素方差分析比较不同年龄组的IFI患者的IFS和QFS的差异。结果:IFI组共计50名患者69例髋,其中50例表现为股方肌卡压伴水肿,9例表现为股方肌卡压伴部分撕裂,8例表现为单纯股方肌卡压和2例表现为单纯股方肌水肿。IFI患者的IFS和QFS分别为15.04±4.20mm和7.33±3.20mm,均明显小于对照组的21.76±4.92mm(t=-12.198,P0.0001)及11.91±4.52mm(t=-12.058,P0.0001)。IFS及QFS诊断界值分别是17mm和9mm,相对应的敏感性、特异性、准确度及ROC曲线下面积分别为:80.9%、70.2%、85.4%及0.928;97.1%,73.9%,84.7%及0.932。不同年龄组IFI患者的IFS及QFS间无显著性差异(P0.05)。结论:股方肌出现形态和(或)信号异常为MRI诊断IFI可靠征象,参考IFS及QFS的诊断界值对IFI诊断具有重要价值。
[Abstract]:Objective: to evaluate the value of MRI in the diagnosis of sciatic femur impingement syndrome (Ifi). Methods: clinical and MRI diagnosis of ischium femur impingement syndrome were used as IFI group. The characteristics of MRI images were analyzed. 34 patients with no clinical symptoms were selected as control group. The ischium femur space and quadratus femoris space were measured in two groups. T test was used to analyze the difference of IFS and QFS between the two groups. The diagnostic thresholds of IFS and QFS were determined by ROC. The differences of IFS and QFS in IFI patients of different age groups were compared by univariate ANOVA. There were 69 hips of 50 patients in IFI group. Among them, 50 cases showed quadratus femoris compression with edema. 9 cases showed quadratus femoris entrapment with partial tear. IFS and QFS were 15.04 卤4.20mm and 7.33 卤3.20mm in 8 patients with simple quadratus femoris muscle compression and 2 patients with simple quadratus femoris edema. It was significantly lower than that of the control group (21.76 卤4.92 mm) and 11.91 卤4.52 mm (P 0.0001) and 11.91 卤4.52 mm respectively (P 0.0001). The diagnostic cutoff values of P0.0001and QFS were 17mm and 9mm, respectively. The sensitivity, specificity, accuracy and area under the ROC curve were 80.9%. 70.2% and 0.928%; 97.1%, 73.9%. 84.7% and 0.932. There was no significant difference in IFS and QFS between patients with IFI in different age groups. Conclusion: the appearance and / or appearance of quadratus femoris muscle is significant. The abnormal signal was a reliable sign of MRI in the diagnosis of IFI. Reference to the diagnostic bounds of IFS and QFS is of great value to the diagnosis of IFI.

【正文快照】： 坐骨股骨撞击综合征(ischiofemoral impingement syndrome,IFI)这一概念在2009年由Torriani等[1]提出,定义为与坐骨结节和股骨小粗隆间隙狭窄相关的髋部疼痛,股方肌出现形态学异常和(或)MRI信号异常。通常情况下股骨小粗隆与坐骨结节始终保持适当的间隙,股方肌位于该间隙内,一
