Prevalence of Femoroacetabular Impingement in Asymptomatic Patients

March 25, 2020 updated by: Ottawa Hospital Research Institute
Femoroacetabular hip impingement syndrome is a newly recognized cause of early arthritis of the hip. In this condition a variation in the shape of the upper thigh bone causes it to repeatedly come in contact with the hip socket leading to cartilage damage and arthritis. The purpose of this study is to investigate whether patients without hip pain have variations at the hip joint such as those seen in hip impingement syndrome.

Detailed Description

Participants in this study will be asked to come to the hospital after regular work hours for an MRI of the hip joints. Prior to the MRI, a physician will perform a range of motion check of the participants hips. The MRI will take approximately 20 minutes during which the participant will have to lie still in a closed space. Participants will receive a letter which can be forwarded to their family doctor if the MRI has any abnormal findings including signs of hip impingement.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
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).
Radiation: 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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Prevalence of Femoroacetabular Impingement (FAI)
Time Frame: Pre-operative on Day of MRI
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).
