The labrum is a type of cartilage that surrounds the socket of ball-and-socket joints. A labrum is found in both the shoulder and the hip joint. The labrum forms a ring around the edge of the bony socket of the joint. It helps to provide stability to the joint by deepening the socket, yet unlike bone, it also allows flexibility and motion.
There are two general types of hip labral tears: degenerative tears and traumatic injuries.
A degenerative tear is a chronic injury that occurs as a result of repetitive use and activity. Degenerative labral tears can be seen in the early stages of hip arthritis.
A traumatic hip labral tear is usually an acute injury as a result of a sports injury, fall, or accident. Hip labral tears are commonly associated with sudden, twisting movements that cause immediate pain in the hip.
