Cam Impingement

Cam Impingement

What is cam type femoroacetabular impingement (FAI)?

Femoroacetabular impingement (FAI) is ‘impingement’ or abnormal contact between the ball (femoral head) and socket (acetabulum) of the hip joint. The cam lesion (or femoral neck ‘bump’) refers to the abnormally-shaped femoral head, which comes into abnormal contact with the edge of the hip socket, thus limiting the range of movement in the hip. This contact frequently results in damage (or tears) to the cartilage along the rim of the socket (i.e., the labrum) or to the cartilage lining the socket (i.e., the articular cartilage). Tears of the hip ligament (i.e., ligamentum teres) may also result.

Treatment of cam-type FAI involves removing the cam lesion and restoring normal bony anatomy. This prevents further impingement and the hip is protected from further damage. Range of motion is also improved. This treatment can be performed via minimally invasive keyhole surgery (hip arthroscopy).
