Motion simulation of 3d ct images to compute joint interference distinguishes between multiple hip pathologies

We developed and tested a radiology-driven framework to simulate hip kinematic motion and articular interference in young and active adults with diagnosed cases of two common hip pathologies. We “place” the hips of thirty-five individuals (15 control; 10 femoroacetabular impingement, FAI; and 10 acetabular dysplasia, AD) via kinematic simulation in one provocative pose, flexion adduction internal rotation (FADIR), and assess patterns of interference. These techniques statistically differentiate FAI from control and dysplastic hips.
