目的：应用MRI探讨正常人群的坐骨-股骨间隙（IFS）宽度的变化与年龄、性别、坐骨间距、股骨颈角等因素的关系。方法：收集我院2016年4—10月行髋关节MRI检查的志愿者的资料共计46例，其中男24例，女22例。测量并记录志愿者的年龄、性别、IFS、坐骨间距等。结果：IFS宽度、股骨头颈轴长的平均值分别为（23.30±6.77） mm、（80.54±6.78） mm，男性组平均值大于女性组（P＜0.05）；坐骨间距、坐骨角的平均值分别为（98.91±13.52） mm、（131.02±4.51）°，女性组平均值大于男性组（P＜0.05）；股骨颈角平均值为（17.79±4.20）°，男、女之间差异无统计学意义（P＞0.05）。IFS宽度与年龄、坐骨间距、坐骨角、股骨颈角呈负相关（P＜0.05），与股骨头颈轴长呈正相关（P＜0.05），与身高、体质量无相关性。结论：女性骨盆结构与男性的差异可能是其更容易罹患坐骨-股骨撞击综合征的原因。随着年龄的增长，IFS宽度逐渐变窄。
Abstract
Objective: To discuss the relationship between the ischiofemoral space(IFS) and elements such as age, gender, intertuberous diameter, the femoral neck angle in asymptomatic population by using MRI. Methods: A total of 46 asymptomatic volunteers(24 with male, 22 with famale) with 1.5T MRI were selected in our hospital from April to October 2016. Age, gender, IFS, intertuberous diameter and other data of volunteers were measured and recorded. Results: The mean width of IFS and femoral neck long axis was(23.30±6.77) mm, (80.54±6.78) mm, respectively. These data of women were lower than that of men(P<0.05). The mean intertuberous diameter and ischial angle was (98.91±13.52) mm, (131.02±4.51)°, respectively. These data of women were higher than that of men(P<0.05). The angle of femoral neck was (17.79±4.20)°, and these data were no significant difference between male and female(P＞0.05). There was a negative correlation between IFS and age, intertuberous diameter, ischial angle, femoral neck angle, and there were a positive correlation between IFS and femoral neck long axis, and there were no correlation between IFS and height, weight. Conclusions: The pelvis differences between women and men may be the cause of ischiofemoral impingement occurring more frequently in women. The width of IFS has gradually decreased with age increased.
