Femoroacetabular impingement FAI is a relatively recently described but important cause of hip pain which frequently affects young and otherwise healthy patients. FAI results from an abnormal contact between the acetabulum and the femur secondary to a variety of morphologic abnormalities of the hip. There are two types of FAI, termed cam impingement and pincer impingement, which have distinct imaging findings. Early diagnosis of FAI is crucial as these patients will frequently develop early osteoarthritis of the hip without timely surgical intervention.
