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 ...
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 .
The transverse acetabular ligament (transverse ligament [1] or Tunstall's ligament [citation needed]) bridges the acetabular notch, creating the a foramen (through which blood vessels and nerves pass into the joint cavity). [2] The ligament is one of the sites of attachment of the ligament of head of femur. [1] [3]: 789
It attaches to the posterior surface of the acetabular rim and acetabular labrum, and extends around the circumference of the joint to insert on the anterior aspect of the femur. [2] The ischiofemoral ligament limits the internal rotation and adduction of the hip when it is in a flexed position. [3]
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 ...
FAI is characterized by abnormal contact between the proximal femur and rim of the acetabulum (hip socket). In most cases, patients present with a deformity in the femoral head, or acetabulum, a poorly positioned femoral-acetabular junction, or any or all of the foregoing. [3]
The acetabular labrum is a fibrocartilagenous structure similar in composition to the meniscus. It is a ring of tissue that surrounds the acetabulum of the pelvis, and allows the head of the femur to articulate smoothly and efficiently with the acetabulum. The labrum plays an important role in maintaining the biomechanical stability of the hip ...
