In the United States acetabular labrum tears usually occur in the anterior or anterior-superior area, possibly due to a sudden change from labrum to acetabular cartilage. [2] The most common labrum tears in Japan are in the posterior region, likely due to the customary practice of sitting on the floor.
The most severe degrees of labral pathology is often unresponsive to labral repair, with damage far too diffuse for focal debridement. In these cases, labral reconstruction is the best option for not only restoring the biomechanics of the acetabular labrum, but for treatment of the patient's pain.

The edge of the acetabulum is surrounded by the acetabular labrum, a fibrous structure that envelops the femoral head. (See fig. 1) The labrum acts as a seal, or gasket, around the femoral head. However, this is not its only function, as it has been shown to contain nerve endings, which may cause pain if damaged. [18]
It involves the surgical correction of any bony abnormalities causing the impingement and correction of any soft tissue lesions, such as labral tears. [6] The primary aim of surgery is to correct the fit of the femoral head and acetabulum to create a hip socket that reduces contact between the two, allowing a greater range of movement. [30 ...
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 capsule of hip joint, articular capsule, or capsular ligament is strong and dense attachment of the hip joint.. Anterosuperiorly, it is attached to the margin of the acetabulum 5 to 6 mm. beyond the labrum behind; but in front, it is attached to the outer margin of the labrum, and, opposite to the notch where the margin of the cavity is deficient, it is connected to the transverse ligament ...
It is bounded by a prominent uneven rim, thick and strong on top, which serves as the point of attachment for the acetabular labrum. 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 ...
Elementary fracture Description Associated fractures Description Posterior wall: This is the most common variety of acetabular fracture. It typically occurs due to dashboard injury; when a person travelling in a vehicle involved in a head-on collision, the force applied over the flexed knee travels along the femur bone to the head of the femur, breaking the posterior wall of the acetabulum.
