摘要
目的:研究健康人群不同体位下坐骨-股骨间隙(IFS)和股方肌间隙(QFS)宽度的变化及其与年龄、性别的关系,为临床诊断坐骨股骨撞击综合征(IFIS)提供影像学依据。方法:招募健康志愿者82例(男性45例,女性37例)。按20~39岁、40~59岁和≥60岁分为3组,分别在中立位、外旋30°和外旋60°体位下行髋关节MRI扫描,比较不同体位、不同性别、不同年龄组间IFS、QFS宽度的差异。结果:健康人群不同体位下女性组IFS和QFS宽度均小于男性组(P<0.05);并且随外旋角度的增加,IFS和QFS宽度有逐渐减小的趋势。不同体位下各年龄组之间IFS、QFS宽度的差异均有统计学意义(P<0.05)。随着年龄的增加,IFS宽度有逐渐减小的趋势。两组间比较除40~59岁组与≥60岁组间IFS、QFS宽度差异无统计学意义外,其余两两间差异均有统计学意义(P<0.05)。不同体位下20~39岁组的IFS、QFS宽度均大于其他两组。结论:健康人群各体位下男性IFS和QFS宽度均大于女性。不同体位下各年龄组间IFS和QFS宽度有一定差异,并且随着年龄的增加IFS宽度有减小的趋势。随着股骨角度增加,IFS和QFS宽度均减小。
Objective:The objective of this study was to investigate the changes of the width of the ischio-femoral space(IFS)and quadratus femoris space(QFS)in normal people at different postures,and to provide imaging basis for clinical diagnosis of ischio-femoral impingement syndrome(IFIS).Methods:A total of 82 normal volunteers were recruited(45 males and 37 females).They were divided into three groups as 20~39,40~59 and≥60 years.MRI scans of hip joint were performed in neutral position and in external rotations at 30°and 60°.IFS and QFS widths at different postures,genders and age were compared.Results:The widths of IFS and QFS in males were significantly higher than those in females at different postures,and the widths of IFS and QFS decreased gradually with the increase of external rotation angle.The widths of IFS and QFS at different postures and ages were significantly different(P<0.05).With the increase of age,the width of IFS decreased gradually.The differences between the two groups were statistically significant except for the differences in IFS and QFS width between the 40~59 years group and the≥60 years group(P<0.05).The widths of IFS and QFS in the 20~39 years group at different positions were larger than those of the other two groups.The widths of IFS and QFS in the 20~39 years group at different positions were larger than those of the other two groups.Conclusion:The widths of IFS and QFS of males at different positions in normal population are larger than those in females.There are differences in the widths of IFS and QFS between different age groups at different postures.With the increase of age,the width of IFS decreases.As the external rotation angle increases,both the IFS and QFS widths decrease.
