Ischiofemoral impingement (IFI) syndrome is the presence of pressure and edema findings in the quadratus femoris muscle due to narrowing of the space between the ischial tuberosity and the lesser trochanter. Our aim is to recognize the deformation or edema of the quadratus femoris muscle in IFI syndrome, to measure the ischiofemoral space (IFS), the width of the quadratus femoris space (QFS) and to compare with the normal group.
Methods:
In this retrospective study, hip MRIs of 100 patients, 50 with IFI syndrome and 50 in the control group, were evaluated. IFS, QFS and quadratus femoris muscles were be evaluated in the patients' hip MRIs. Edema and fatty atrophy in the quadratus femoris muscle were categorized as 4 degrees. Differences in IFS, QFS, quadratus femoris muscle edema and fatty infiltrations between the two groups were be evaluated.
Results:
The mean IFS and QFS in the case group were significantly smaller than in the control group. There was a statistically significant difference between the two groups (p < 0.001). Also, female IFS and QFS widths were smaller than male IFS and QFS widths; there was a statistically significant difference between the 2 groups (p < 0.001). There was a strong positive (r = 0.933) and significant (p < 0.001) correlation between IFS and QFS. There was a statistically significant difference in the ischiofemoral distance and quadratus femoris distances between the control group with no edema and fatty atrophy in the quadratus femoris muscle and the case group with varying degrees of edema and fatty atrophy (p <0.001).
Conclusions:
In conclusion, narrowing of the ischiofemoral and quadratus femoris distances causes impingement in the quadratus femoris muscle and is a cause of posterior hip pain. MRI examination can provide reliable information for the evaluation of ischiofemoral impingement syndrome
