Prevalence of Femoroacetabular Impingement in Asymptomatic Patients

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.

About this study

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.

Primary outcomes

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).
