What is Femoral-Acetabular impingement (FAI)?
Femoroacetabular impingement (FAI) is a condition where the shape of the femoral neck of acetabulum are abutting one another causing pain or damage. There are two types (or a combination of both):
- CAM impingement: is when there is a bump lesion on the femoral neck that impinges on the acetabulum (the socket)
- Pincer impingement: is when the acetabulum (the socket) is protruding out and impinging on the femoral neck.
