Acetabular labrum
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 apex represented by the free margin).[2][3]
Not to be confused with Lunate surface of acetabulum.Acetabular labrum
The labrum contributes to the articular surface of the joint[2][1] (increasing it by almost 10%[1]). It embraces the femoral head,[2] holding it firmly in the joint socket[3] to stabilise the joint. It thus also seals the joint cavity, facilitating even distribution of synovial fluid so that friction is reduced and dissolved nutrients are better distributed.[2]
The anterior portion of the labrum is most susceptible to tears.
