Brief Summary

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.

Conditions

Femoro-acetabular Impingement

Outcome Measures

Primary Outcomes (1)

• 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.
