acetabular labrum

The acetabular labrum is a ring of soft, fibrous tissue that surrounds the edge of the hip socket (acetabulum). Its main functions are to deepen the socket, providing stability to the hip joint, and to help keep the ball of the thigh bone (femoral head) securely in place. The labrum also helps cushion the joint and maintain the flow of lubricating fluids, which keeps the cartilage healthy. Damage or tears to the labrum can cause pain, stiffness, and instability, often resulting from injury or wear over time.
