Study of Hip Bone Shape and Movement in Adult Men With and Without Femoroacetabular Impingement Using 3D Motion and Full-Body X-Ray Imaging

What this Trial Is About

Researchers are investigating femoroacetabular impingement FAI, an orthopedic condition where abnormal bone shapes in the hip cause painful contact during movement. This study focuses on adult males aged 21 to 35 and aims to explore how spinopelvic anatomy and biomechanics contribute to FAI symptoms. The project uniquely combines advanced 3D motion analysis with full-body biplanar X-ray imaging to better understand the relationship between hip and pelvic motion and symptomatic FAI. Participants will be divided into three groups males with symptomatic CAM-type FAI, males with asymptomatic CAM morphology, and healthy males with no abnormal hip features. Each subject undergoes detailed diagnostic assessments, including low-dose full-body X-rays in various positions and hip-specific 3D motion analysis during daily and athletic movements. Movements such as walking, squats, lunges, and running are repeated multiple times while data is collected with motion capture systems and an instrumented treadmill. Throughout the study, researchers will measure the presence of CAM morphology with symptoms, hip and pelvic X-ray parameters, and 3D motion data. Participants will complete outcome questionnaires like the Copenhagen Hip and Groin Outcome Score. This comprehensive approach aims to identify biomechanical differences between symptomatic and asymptomatic individuals. The trial will include safety monitoring and follow participants until study completion in late 2026.
