Labrum

Labrum

The Labrum is a fibrocartilaginous structure that is attached around the margin of the hip joint. In the human body, there are two labra - one in the shoulder and the other in the hip. The function of the labrum is to deepen the socket and provide a suction seal for the joint.

Anatomy

The labrum is a type of cartilage found in the shoulder and hip joints. It is a ring of tough, fibrous tissue that surrounds the socket of the joint. In the shoulder, it is called the glenoid labrum, while in the hip, it is called the acetabular labrum.

Function

The labrum serves several important functions in the body. It deepens the socket of the joint, providing more stability and reducing the risk of dislocation. It also acts as a shock absorber, cushioning the joint against impact and wear. Additionally, the labrum helps to maintain the suction seal of the joint, which is important for maintaining joint health and function.

Clinical significance

Damage to the labrum can cause a variety of problems, including pain, instability, and loss of function. Labral tears are a common injury, especially in athletes and people who perform repetitive overhead movements. These tears can be caused by trauma, degeneration, or structural abnormalities.

Treatment for labral tears typically involves physical therapy, medication, and in some cases, surgery. The goal of treatment is to reduce pain and inflammation, improve function, and prevent further damage to the joint.
