The hip joint is a ball and socket joint, around the rim of the socket is a labrum. The labrum is a cartilaginous ring around the socket and improves the stability of the hip.
The hip labrum has the same function like the glenoid labrum in the shoulder. The labrum covers the rim of the acetabulum (where the head of the femur connects with the pelvis) (Guanche, 2010).
There are multifactorial reasons for labral tears (Guanche, 2010): the labrum can be damaged either by injury or trauma to the hip, resulting from an impingement, by a sudden movement of pivoting or twisting or by developmental hip problems.
If possible conservative with resting, reduced level of activity and physiotherapy; in severe cases hip arthroscopy is the treatment of choice.
