Hip Anatomy Labrum

This is lined by a ring of cartilage called the labrum. 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.

Hip labrum anatomy and function.

Hip anatomy labrum. The hip like the shoulder has a labrum. 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. Many of the symptoms of a hip labral tear are similar to symptoms of a groin strain snapping hip syndrome sports hernia or other athletic injuries of the hip joint.

A damaged labrum can also result in a shift of the hip center of rotation. The intact labrum seals the lubricating fluid within the hip and contributes to stability of the joint. It also helps regulate the fluid within the joint.

The hip labrum is a ring of strong flexible cartilage that rims the outer edge of the hip socket acetabulum. The labrum supplies cushioning and support for the hip joint. Medical definition of labrum.

The term labrum is used in anatomy to designate a lip edge or brim. The labrum deepens this cavity the glenoid cavity. The labrum serves several purposes including.

The socket of the hip joint that the thigh bone sits in is called the acetabulum. 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. Anteriorly and posteriorly the attachment of the capsule is much closer to the base of the labrum.

A change of this type increases the impact and load on the joint. The labrum is well innervated and thus injury to the labrum can result in pain. Acetabular labrum the labrum is a fibrous cartilage ring which lines the acetabular socket.

Understanding hip anatomy is important to understanding a labral tear and its possible effects. Superiorly the capsules attachment is removed from the labrum by a few millimeters forming the perilabral sulcus. Tears can occur in the labrum also known as a hip labral tear or acetabular labral tear.

Furthermore just because a tear is seen in the hip labrum on an mri it does not mean the tear is necessarily the cause of the pain. The capsule of the hip joint attaches to the margins or immediately adjacent to the acetabulum and transverse ligament. A hip labral tear can be difficult to diagnose.

It deepens the cavity increasing the stability and strength of the hip joint.
