Labrum

The labrum is a ring of cartilage that surrounds the socket of certain joints, like the shoulder and hip. It acts like a bumper or gasket, deepening the socket to help stabilize the joint and provide attachment points for ligaments and tendons. This structure helps prevent dislocation and allows for smooth movement. When the labrum is torn or damaged, it can cause pain, instability, or a catching sensation in the joint, often resulting from injury or repetitive stress. Treatment varies from rest and physical therapy to surgical repair, depending on the severity of the damage.
