Brief Summary

In this study, the investigators seek to describe the normal 3D hip joint morphology in asymptomatic volunteers and compare it to various hip joint deformities. Asymptomatic volunteers will be asked to undergo a non-contrast MRI of the hip at 3 Tesla, utilizing a high-resolution morphologic 3D sequence (3D T2 DESS) that enables the segmentation of labrum and cartilage. 3D morphological parameters of the asymptomatic group will subsequently be compared with the 3D morphological parameters of patients with hip deformities, which were collected as part of a previous retrospective study.

Hip Dysplasia

This group is defined according to the following radiographic parameter: lateral center edge angle (LCE) \< 23°. The data was obtained from a retrospective study.
