[3] Sporting activities are likely causes, specifically those that require frequent lateral rotation or pivoting on a loaded femur as in hockey or ballet.

[1] Constant hip rotation places increased stress on the capsular tissue and damage to the iliofemoral ligament.

[3] Traumatic injuries are most commonly seen in athletes who participate in contact or high-impact sports like football, soccer, or golf.

Since there is very little soft tissue to diminish the force between the impact and the greater trochanter, the entire blow is transferred to the surface of the hip joint.

[6] Tears of the hip labrum can be classified in a variety of ways, including morphology, etiology, location, or severity.

Impingement occurs when the femoral head rubs abnormally or lacks a full range of motion in the acetabular socket.

The increased stresses that the femur and or acetabulum experience may lead to a fracture of the acetabular rim or a detachment of the overstressed labrum.

[2] The most common labrum tears in Japan are in the posterior region, likely due to the customary practice of sitting on the floor.

[1] An acetabular labrum tear can occur in a variety of ways such as frequent twisting movement, direct trauma, or degeneration.

[1] But many hip labral tears are not directly related to any specific action,[4] making it difficult to prevent such an injury.

It may be possible to lower the risk by strengthening the gluteus, stretching before exercise, and discontinuing the use of repetitive twisting activities.

The top leg is raised keeping the knee and hip straight; especially effective where there is an anterior pelvic tilt.

[1] A warm-up using body weight squats can induce creep before exercise to help prevent a hip labrum tear.
