Hip Impingement
Hip Impingement
Hip impingement, also known as femoroacetabular impingement (FAI), occurs when the ball of the hip (femoral head) presses against the hip cup (acetabulum). When this happens, the labrum (cartilage that surrounds the acetabulum) can be damaged, causing hip stiffness and pain and eventually leading to arthritis.
Causes and Risk Factors
Many people believe that the abnormal shape has been present since birth. However, this abnormal shape can also develop over time and is more common in young athletes who participate in sports that require a lot of hip twisting and squatting.
