The acetabular labrum is a ring of cartilage located in the hip joint, specifically around the edge of the acetabulum, which is the socket of the hip bone. This structure helps to deepen the socket, providing stability and support to the joint. It also plays a role in distributing weight and reducing friction during movement. In addition to its stabilizing function, the acetabular labrum contains nerve endings that contribute to proprioception, which is the body's ability to sense its position in space. Damage or injury to the labrum can lead to pain and decreased mobility, often requiring medical evaluation and treatment.
