Trial Outcomes & Findings for Prevalence of Femoroacetabular Impingement in Asymptomatic Patients (NCT NCT00606047)

NCT ID: NCT00606047

Last Updated: 2020-03-27

Results Overview

Prevalence of femoroacetabular impingement (FAI), a newly recognized cause of early arthritis of the hip, will be investigated by means of hip MRI to evaluate for abnormal morphology of the anterior head-neck junction of the femur. Participant MRIs were reviewed by two independent radiologists. The prevalence of FAI was calculated as determined by an abnormal alpha angle (greater than 50.5 degrees).

Measure
Asymptomatic Patients
Asymptomatic, healthy patients (without hip pain or prior hip disease) will be recruited. Patients will undergo a magnetic resonance imaging (MRI) of the hip joints to evaluate for the prevalence of femoroacetabular impingement (FAI). Magnetic resonance imaging (MRI): Participation in this study will involve patients coming to the hospital after regular work hours for an MRI of the hip joints.
