Femoroacetabular impingement (FAI) is a cause of progressive osteoarthritis of the hip in younger patients. Three types of FAI have been described: a cam-type, a pincer-type and a mixed type. Early recognition of the morphologic hip features of each type of impingement is important, because arthroscopic treatment is still successful in the initial stage to prevent or delay further hip degeneration. This article reviews the imaging features of the different types of FAI. Magnetic resonance arthrography (MRA) is the preferred modality to detect, localise and characterise the type of FAI and the resulting injuries of the acetabular hyaline cartilage and fibrocartilaginous labrum.
股骨髋臼撞击症（FAI）是年轻患者髋关节进行性骨关节炎的一个病因。已描述了三种类型的FAI：凸轮型、钳夹型和混合型。早期识别每种撞击类型的髋关节形态学特征很重要，因为在初始阶段进行关节镜治疗仍能成功预防或延缓髋关节进一步退变。本文综述了不同类型FAI的影像学特征。磁共振关节造影（MRA）是检测、定位和鉴别FAI类型以及髋臼透明软骨和纤维软骨盂唇所致损伤的首选检查方法。
