The main objective is to show that the upper acetabular anteversions calculated in standing, sitting, sitting hip in maximum flexion and supine positions are lower in patients with symptomatic DWI compared to healthy volunteers.
Patient at least 18 years of age but < 50 years of age
Patient with a confirmed diagnosis of DWI for whom arthroscopic impingement surgery is proposed
Patient who has given and signed free and informed consent
A patient who is a member of a social security plan or a beneficiary of such a plan
Patient who has already undergone surgery on the same hip
Patient with previous spine surgery
Patient already included in the study for the opposite hip
Pregnant or breastfeeding patient
Parallel
Scanner and EOS imaging
Other interventionCross-sectional imaging and 3D reconstruction to measure and compare acetabular anteversion in 4 functional pelvic positions.
Anteversions comparison
Comparison of anteversions of the superior plane of the acetabulum obtained from 3D CT reconstruction of the pelvis positioned standing, seated, seated hip in maximum flexion, and supine after matching by low-dose EOS X-ray images, between patients with symptomatic DWI and healthy volunteers.
