Biomechanical Investigation of Symptomatic FAI and Two Groups of Asymptomatic Controls

Conditions studied: Femoroacetabular Impingement
In brief
Femoroacetabular impingement (FAI) is an orthopaedic condition that is primarily characterized by the presence of anatomic bony abnormalities in the femoral head and/or the acetabulum resulting in an abnormal contact between the two during hip motion, especially in positions of increased hip flexion and rotation, ultimately leading to hip pain. Unfortunately, a FAI diagnosis is frequently only made once symptoms have become severe to an extent that they limit everyday life activities. Moreover, another important aspect that has been consistently overlooked in past FAI movement studies is the influence muscle strength and activation can have on movement pattern and symptom presentation. The diagnosis and management of FAI needs to be addressed through a more wholesome investigation of the biomechanical influence on the manifestation of symptoms. This project aims to further unravel the link between spinopelvic anatomy, its biomechanical contribution to femoro-pelvic motion and the manifestation of femoroacetabular impingement in adult male population. By, for the first time, integrating three-dimensional (3D) instrumented motion analysis with state-of-the-art full-body biplanar X-ray imaging (EOS imaging, Paris France), we will more specifically investigate the presence of an association between spinopelvic kinematics and the link to symptomatic FAI morphology, as well as investigate the presence of differences in these measures between symptomatic and asymptomatic subjects with comparable femoral morphology.
