Femoroacetabular impingement syndrome is a condition arising from a mechanical conflict between the proximal femur and acetabulum. The standard initial imaging method when this impingement is suspected is an anteroposterior radiograph of the pelvis and an axial view of the proximal femur. In imaging examinations, the axial radiograph is often overlooked or not performed correctly, which may result in underdiagnosis of this significant condition. In this article, we present a review of the literature concerning femoroacetabular impingement syndrome and a case report demonstrating the use of ultrasound in diagnosing this disease.
