Labrum SLAP Tear
A labrum SLAP tear is a tear in the cartilage that is part of your shoulder joint.
A labrum is a rim of cartilage that goes around the socket part of a ball-and-socket joint. In your shoulder, this is called the glenoid labrum. You also have a labrum in each hip joint.
Your shoulder has three bones: the scapula (shoulder blade), humerus (upper arm bone), and clavicle (collarbone). They work together in a ball-and-socket joint where your arm connects to your trunk.
Your labrum is soft tissue that connects the socket part of the scapula (called the glenoid) with the head of the humerus. A tear in the labrum results in insufficient cushioning between those bones.
