[Femoroacetabular impingement: association between the over-coverage and acetabular cartilage delamination areas].
BACKGROUND Femoroacetabular impingement (FAI), it is a clinical syndrome relatively recently recognized as source of hip mechanic pain and early osteoarthritis. Two types of FAI have been described, based on the bone morphology and pattern of chondral and labral damage; the cam type is frequently associated with chondral delamination; and the pincer type is associated with a contre-coup injury ...

متن کاملHip-femoral acetabular impingement.
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...
متن کاملComparison of MRI alpha angle measurement planes in femoroacetabular impingement.
Insufficient femoral head-neck offset is common in femoroacetabular impingement (FAI) and reflected by the alpha angle, a validated measurement for quantifying this anatomic deformity in patients with FAI. We compared the alpha angle determined on magnetic resonance imaging (MRI) oblique axial plane images with the maximal alpha angle value obtained using radial images. The MRIs of 41 subjects ...
