Corrections in alpha angle following two different operative approaches for CAM-type femoral acetabular impingement - Ganz surgical hip dislocation vs anterior mini-open

Figure 1 A 31-year-old male with bilateral hip femoroacetabular impingement with left hip treated using Ganz surgical hip dislocation while right hip treated through anterior mini-open approach. Both hips showed adequate correction of alpha angle (Top panels: Post-operative cross-table lateral X-ray images. Bottom panels: Showing measurement of alpha angle with left hip being 45 degrees and right being 42 degrees).
