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., conditionsModule conditions: Femoroacetabular Impingement, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: NON_RANDOMIZED, interventionModel: PARALLEL, interventionModelDescription: Cross-sectional, case-control prospective clinical study, primaryPurpose: DIAGNOSTIC, maskingInfo masking: SINGLE, maskingDescription: 3 study groups, based on clinical examination and medical imaging:* symptomatic CAM-FAI patients* asymptomatic CAM controls* healthy controls, whoMasked: PARTICIPANT, enrollmentInfo count: 99, type: ESTIMATED, armsInterventionsModule interventions name: EOS, interventions name: 3D motion lab analysis, outcomesModule primaryOutcomes measure: The presence of CAM morphology in combination with symptoms, secondaryOutcomes measure: The Copenhagen Hip and Groin Outcome Score (HAGOS), secondaryOutcomes measure: Radiographic spinopelvic parameters, secondaryOutcomes measure: 3D motion analysis parameters, eligibilityModule sex: MALE, minimumAge: 21 Years, maximumAge: 35 Years, stdAges: ADULT, contactsLocationsModule locations facility: University Hospitals of Leuven, status: RECRUITING, city: Leuven, state: Vlaams-Brabant, zip: 3000, country: Belgium, contacts name: Stijn Ghijselings, MD, role: CONTACT, phone: +32 16 33 88 18, email: stijn.ghijselings@uzleuven.be, contacts name: Orthopedic Research, role: CONTACT, phone: +32 16 33 88 18, email: orthopedie.research@uzleuven.be, geoPoint lat: 50.87959, lon: 4.70093, hasResults: False
