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.
