Cam FAI is characterized by a non-spherical ...

Magnetic resonance imaging (MRI) has become a valuable technology for the diagnosis and treatment of femoroacetabular impingement (FAI). This article reviews the basic pathophysiology of FAI, as well as the techniques and indications for MRI and magnetic resonance arthrography. Normal MRI anatomy of the hip and pathologic MRI anatomy associated with FAI are also discussed. Several case examples...

The acetabular labrum is a critical structure within the hip joint. It is a significant cause of pain, and it plays an integral role in the development of osteoarthritis. This article reviews the normal anatomy, imaging techniques, and normal MR appearance of the labrum. The clinical presentation of labral tears and their association with developmental dysplasia and femoroacetabular impingement...

Arthroscopic treatment of chondral lesions of the hip is challenging. Understanding the etiology is paramount not only in treating hip chondral damage but also in mitigating the cause, using arthroscopic means. This article addresses chondral lesions of the hip caused by either injury or morphologic conflicts such as seen in femoroacetabular impingement. Fractures, aseptic necrosis, and metabol...

Femoroacetabular impingement (FAI) is a mechanical process by which the human hip fails due to pathological contact between the skeletal prominences of the acetabulum and the femur. This repetitive pathological contact occurs during normal activities of daily living as well as, more prominently, in an athletic population. This causes a microtraumatic effect and subsequently irreversible chondra...

A growing interest exists in the diagnosis and treatment of femoroacetabular impingement. Although cam morphology of the proximal femur may conceptually appear to be a relatively simple topographical aberrancy, it is actually positioned amid a complex developmental, kinematic, and biomechanical region of the human body. The authors introduce a new classification scheme and review the historical...
