A CT-based method ("HipMotion") for the noninvasive three-dimensional assessment of femoroacetabular impingement (FAI) was developed, validated, and applied in a clinical pilot study. The method allows for the anatomically based calculation of hip range of motion (ROM), the exact location of the impingement zone, and the simulation of quantified surgical maneuvers for FAI. The accuracy of HipMo...

Femoroacetabular impingement (FAI) is an increasingly recognized condition, which is believed to contribute to degenerative changes of the hip. This correlation has led to a great deal of interested in diagnosis and treatment of FAI. FAI can be divided into two groups: cam and pincer type impingement. FAI can lead to chondral and labral pathologies, that if left untreated, can progress rapidly ...

Femoroacetabular impingement (FAI) is a clinical syndrome resulting from abnormal hip joint morphology and is a common cause of hip pain in young adults. FAI has been posited as a precursor to hip osteoarthritis (OA); however, conflicting evidence exists and the true natural history of the disease is unclear. The purpose of this article is to review the current understanding of how FAI damages ...

British Journal of General Practice, July 2013 e513 INTRODUCTION Femoroacetabular impingement (FAI) is a pathological hip condition characterised by abnormal contact between the acetabulum and femoral head–neck junction.1 This can occur within the normal physiological range of motion as a result of osseous abnormalities described as either cam or pincer deformities. Cam deformities describe an ...

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...
