The concept of femoroacetabular impingement (FAI) emerged following the observation that FAI can be precipitated by acetabular reorientation and can produce new labral damage. Interest in the association between chondrolabral damage and variations in femoral and acetabular anatomy has established a causal relationship between mechanical aberration in the function of the hip joint and the development of labral and cartilage damage. The accepted definition of FAI is that it is characterized by abnormal mechanical contact between the rim of the acetabulum and the upper femur. Combinations of certain morphologies and movements may lead to FAI.
股骨髋臼撞击症（FAI）的概念是在观察到髋臼重新定向可引发FAI并能导致新的盂唇损伤后出现的。对软骨盂唇损伤与股骨和髋臼解剖结构变异之间关联的关注，确立了髋关节功能中的机械异常与盂唇和软骨损伤发展之间的因果关系。FAI的公认定义是其特征为髋臼边缘与股骨上端之间存在异常机械接触。某些形态和运动的组合可能导致FAI。
