Femoroacetabular impingement (FAI) is a painful and early contact between the proximal femur and the acetabular rim or the pelvis. The pathological bony abutment typically leads to a characteristic pattern of chondrolabral damage and is one of the main reasons for development of early osteoarthritis in the young hip joint. Classically, FAI was described as an intraarticular problem but the extraarticular impingement has recently gained in importance. This article provides an overview of the concept of FAI, the clinical presentation, the radiological assessment including its coxometric parameters and the treatment options currently available.

Der Artikel beschreibt anhand von Fallbeispielen die verschiedenen Typen von FAI, die klinischen Symptome, die typischen Zeichen in der Bildgebung sowie die verschiedenen Behandlungsmöglichkeiten.
