ClinConnect Summary

This clinical trial is studying a condition called femoroacetabular impingement (FAI), which causes hip pain due to abnormal contact between the hip joint's bones during movement. The researchers want to better understand how the structure of the spine and pelvis affects hip motion and contributes to FAI symptoms, especially in young adult males. They will use advanced imaging techniques to look at bone movement and compare individuals who have symptoms with those who do not, even if they have similar bone shapes.

To join the study, participants must be males aged 21 to 35 years old. There are specific requirements based on their hip condition: some must have a specific type of FAI (called CAM-FAI), while others must be asymptomatic controls with similar bone structures or healthy controls with no symptoms at all. Participants can expect to undergo detailed imaging and motion analysis to help researchers learn more about this condition and improve diagnosis and treatment options in the future. It's important to note that those with certain types of joint problems, like osteoarthritis or a different type of FAI, won't be eligible for this trial.
