Purpose: The aim of this study is to evaluate the MR imaging features of patients with external snapping hip syndrome.
Materials and Methods : We retrospectively reviewed 63 hip MR images. The images were analyzed according to the thickness and contour of the iliotibial band and the gluteus maximus, the presence of bone marrow edema, bursitis, joint effusion and other associated findings.
Results: The MR imaging of 22 hips with snapping hip syndrome depicted the causes of external snapping hip syndrome in twenty cases (90%). The MR imaging features of the snapping hip included thickening of the iliotibial band in twelve cases (55%) and/or thickening of the anterior band of the gluteus maximus in nineteen (86%), and a wavy contour of the iliotibial band or the anterior band of the gluteus maximus in ten cases (45%). These findings show a significant p value (<0.01).
Conclusion: The majority of patients with snapping hip syndrome revealed thickening of the iliotibial band, thickening of the anterior band of the gluteus maximus and wavy contour of the those structures on MR imaging.
