Hip Labrum Anatomy

Understanding hip anatomy is important to understanding a labral tear and its possible effects. A change of this type increases the impact and load on the joint.

A damaged labrum can also result in a shift of the hip center of rotation.

Hip labrum anatomy. It provides an articulating surface for the acetabulum allowing the head of the femur to articulate with the pelvis. In addition to cushioning the hip joint the labrum acts like a rubber seal or gasket to help hold the ball at the top of your thighbone securely within your hip socket. The hip labrum is a ring of strong flexible cartilage that rims the outer edge of the hip socket acetabulum.

The intact labrum seals the lubricating fluid within the hip and contributes to stability of the joint. Athletes who participate in such sports as ice. The labrum serves several purposes including.

The anterior portion is most vulnerable when the labrum tears. Hip labrum anatomy and function. The hip labrum has many functions including shock absorption joint lubrication pressure distribution and aiding in stability with damage to the labrum associated with osteoarthritis.

Without the protection of the seal or with a hip thats off center repetitive motion can create multiple small injuries to the labrum and to the hip joint. The acetabular labrum is a ring of cartilage that surrounds the acetabulum of the hip. The glenoid labrum is a ring of fibrocartilage that runs around the cavity of the scapula wingbone in which the head of the humerus the bone in the upper arm fits.

A hip labral tear involves the ring of cartilage labrum that follows the outside rim of the socket of your hip joint. The acetabular labrum is a c shaped fibrocartilaginous structure with an opening anteroinferiorly at the site of the acetabular notch. The hip is a ball and socket synovial joint formed by the articulation of the femoral head with the acetabulum.

The hip like the shoulder has a labrum. The acetabular labrum is a fibrocartilaginous structure like the glenoid labrum and it is shaped to outline the acetabular socket. The acetabulum covers 170 of the femoral head.

The etiology of labral tears includes trauma femoroacetabular impingement fai capsular laxityhip hypermobility dysplasia and degeneration. Here it is bridged by the transverse ligament thus forming the acetabular foramen beneath it. The labrum deepens this cavity the glenoid cavity and effectively increases the surface of the shoulder joint.

Elsewhere it is attached to the margins of the acetabulum. A ring of rubbery fibrocartilage around the rim of the acetabulum which deepens the hip socket and acts as the suction seal of the hip joint.
