Among all the tears, the first type of tear is the one in which the labrum is torn completely from the bone. This type of injury is usually related to a shoulder injury in which the shoulder is subluxated or dislocated. Sometimes, this tear occurs and the individual does not realize that the shoulder has slipped out of its socket. This can make the situation worse and cause other types of ligament injuries around the shoulder. The second type of lip tear is a tear inside the actual lip. The sides of the lip may fray after a while, which is a slight tear where the lip slowly begins to unravel like a thread, so that the edge is no longer even and smooth. This type of tearing has been shown to be quite common and rarely causes symptoms. It is often seen in the shoulder as people age. Sometimes the labrum may have a large tear where a portion of the labrum enters the joint and causes clicking and jamming as the ball moves in the socket. This lesion is seen very rarely, and most other included labrum lesions do not cause these symptoms. The third type of labral tear is found in the area where the biceps tendon attaches to the upper end of the orbit. The alveolus can be divided into four different regions: anterior, posterior, superior and inferior. A SLAP tear is a type of labral tear most commonly seen in overhead throwing athletes such as baseball players and tennis players. SLAP stands for anterior to posterior superior labral tear. The torn labrum seen in a SLAP injury is located at the top of the shoulder socket, where the biceps tendon attaches to the shoulder (Shoulder SLAP Injury - Topic Overview). A Bankart lesion is a labral tear that occurs when a shoulder dislocates. When the shoulder is in the center of the paper, the socket of the hip bumps against the two bones to create a cushion. Its function is to narrow the spacing of the hip joint, increase stability and equalize joint stress. The stability afforded by the labrum allows for normal physical function such as walking. The hip labrum or acetabular is a ridge of cartilage that runs around the edge of the hip joint. The purpose of the cartilages is to create a deeper and more stable hip socket. The labrum can be torn from its attachment and cause pain, clicking, or entrapment (Hip Labral Tear, Mayo Clinic Staff). The labrum can tear for many reasons. Some people tear their labrum due to falls or sports injuries when the hip is forced into extreme positions. It can also be damaged by repeated trauma in sports that require regular rotation of the hip (A Patient's Guide to Labral Tears of the Hip, The Methodist Hospital System).
