title: Femoroacetabular impingement.
abstract: Femoroacetabular impingement, both cam and pincer types, is a recently appreciated cause of hip pain, acetabular cartilage and labral damage, and hip degenerative change. Abnormalities in the morphology of the acetabulum or the proximal femur may be the primary predisposing factor. This article reviews the imaging findings and treatment strategies of cam- and pincer-type femoroacetabular impingement.
