目的研究成年无症状人群的坐骨股骨间隙(IFS)及股方肌间隙(QFS)宽度的变化范围,并分析与年龄、性别的关系。方法搜集2015年3月至2015年12月共计103名无症状志愿者进行1.5 T MRI检查,其中男43名,女60名。按年龄段分为3组,青壮年组18~39岁,中年组40~59岁,老年组60~80岁。对206个髋关节的IFS宽度、QFS宽度进行测量并记录。结果无症状人群中IFS、QFS宽度分别为(24.01±7.11)mm、(19.20±7.50)mm,QFS左右侧不对称,差异有统计学意义(P<0.05)。青年组IFS宽度比老年组宽,差异有统计学意义(P<0.05),青年组QFS宽度比中年组和老年组都宽,差异均有统计学意义(P<0.05)。IFS、QFS宽度与年龄均呈负相关(相关系数r分别为-0.271、-0.306,P均<0.05)。男性的IFS、QFS宽度平均值大于女性,差异有统计学意义(P<0.05)。结论成人无症状人群中双侧的IFS、QFS宽度并非完全对称,男性大于女性,且随着年龄的增加宽度有缩小的趋势。
Objective To investigate the range of width of isthmic femoral space (IFS) and quadriceps femoris (QFS) in asymptomatic adults and to analyze the relationship with age and gender. Methods A total of 103 asymptomatic volunteers from March 2015 to December 2015 were enrolled in the 1.5 T MRI examination, including 43 males and 60 females. By age group is divided into 3 groups, young adults 18 to 39 years old, middle-aged group 40 to 59 years old, aged 60 to 80 years. The IFS width and QFS width of 206 hips were measured and recorded. Results The width of IFS and QFS in asymptomatic subjects were (24.01 ± 7.11) mm and (19.20 ± 7.50) mm, respectively. There was a statistically significant difference in left and right QFS (P <0.05). The width of IFS in youth group was wider than that in elderly group (P <0.05). The QFS width in youth group was wider than that in middle age group and elderly group (P <0.05). IFS, QFS width and age were negatively correlated (r = -0.271, -0.306, P <0.05 respectively). The average width of IFS and QFS in males was greater than that in females, with significant difference (P <0.05). Conclusion The bilateral IFS and QFS widths in asymptomatic adults are not completely symmetrical. The male is larger than the female, and the width decreases with age.
