With all of the tears, the first type of tear is one where the labrum is torn all of the way off of the bone. This type of tear usually correlates with an injury to the shoulder where the shoulder has subluxated or dislocated. Sometimes, this tear occurs and the individual does not realize that the shoulder has slid out of the socket. This can make it much worse and cause other types of injuries to the ligaments around the shoulder.
The second type of labrum tear is tearing within the actual labrum. The sides of the labrum after a while may get frayed, meaning a slight tear where the labrum slowly starts to unravel like yarn, so that the edge is no longer even and smooth. This type of tearing is proven to be pretty common and rarely causes symptoms. It is often times seen in the shoulder as people get older. Sometimes the labrum may have a large tear where a portion of the labrum gets into the joint and causes clicking and catching as the ball moves around in the socket. This tear is very rarely seen, and most of the other included labrum tears will not cause these symptoms.
The third type of labrum tear is in the area where the biceps tendon attaches to the upper end of the socket. The socket is able to 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 Superior Labral tear from Anterior to Posterior. The torn labrum seen in a SLAP tear is at the top of the shoulder socket where the biceps tendon attaches to the shoulder (Shoulder SLAP Tear - Topic Overview).

... hip’s socket bumping up against the two bones to create a cushion. Its function is to tighten the hip joint’s spacing, increase stability and even out joint stress. The stability the labrum allows permits normal physical function such as walking. The hip or acetabular labrum is a ridge of cartilage that runs around the rim of the hip joint socket. The cartilages purpose is to create a deeper and more stable hip socket. The labrum is able to be ripped away from its attachment and cause pain, clicking or catching (Hip Labral Tear, Mayo Clinic Staff).
The labrum can tear for many reasons. Some people tear their labrum from falls or sporting injuries when the hip is forced into extreme positions. It can also be damaged by repetitive trauma in sports that require regular rotation of the hip (A Patient's Guide to Labral Tears of the Hip, The Methodist Hospital System).
