Abstract

Objective: We aim to determine if pelvic incidence (PI) differed between a symptomatic femoroacetabular impingement (FAI) population and a control.

Methods: We retrospectively identified a cohort of symptomatic FAI patients and compared measured PI to a control group.

Results: The PI was significantly lower in the FAI group compared to the control (51.32±1.07 vs. 55.63±1.04; P < 0.01).

Conclusion: The mean PI was significantly decreased in the FAI population compared to a control.

Keywords: False profile; Femoroacetabular impingement; Pelvic incidence; Spinopelvic parameters.
