An acetabular labrum tear or hip labrum tear is a common injury of the acetabular labrum resulting from a number of causes including running, hip dislocation, and deterioration with ageing. Most are thought to result from a gradual tear due to repetitive microtrauma .
It occurs when the ball shaped femoral head contacts the acetabulum abnormally or does not permit a normal range of motion in the acetabular socket. [3] Damage can occur to the articular cartilage, or labral cartilage (soft tissue, ring-shaped bumper of the socket), or both. [4] The condition may be symptomatic or asymptomatic.
A hip labral tear is characterized by damage to cartilage surrounding the outer rim of the hip joint. Some studies suggest that hip labral tears could be the reason for up to 55 percent of cases ...
The acetabular labrum (glenoidal labrum of the hip joint or cotyloid ligament in older texts) is a fibrocartilaginous ring [1] [2] [3] which surrounds the circumference of the acetabulum of the hip, deepening the acetabulum. The labrum is attached onto the bony rim and transverse acetabular ligament. It is triangular in cross-section (with the ...
The acetabular labrum reduces the size of the opening of the acetabulum and deepens the surface of the hip joint. At the lower part of the acetabulum is the acetabular notch, which is continuous with a circular depression, the acetabular fossa, at the bottom of the cavity of the acetabulum. The rest of the acetabulum is formed by a curved ...
A complex labral tear. An arthroscopic probe is seen at the junction of the labrum and acetabular rim. Hip arthroscopy was initially used for the diagnosis of unexplained hip pain, but is now widely used in the treatment of conditions both in and outside the hip joint itself.
The bumper keeps the ball on the track. The labrum tries to keep the ball in the socket, and the shoulder socket is a pretty shallow joint. It's not as confined as a hip joint. The labrum deepens ...
