Definition: A Bankart tear is a specific injury to a part of the shoulder joint called the labrum. The shoulder joint is a ball-and-socket joint, but the socket of the shoulder joint is extremely shallow, and thus inherently unstable. To compensate for the shallow socket, the shoulder joint has a cuff of cartilage called a labrum that forms a cup for the end of the arm bone (humerus) to move within.
When the labrum of the shoulder joint is torn, the stability of the shoulder joint is compromised. A specific type of labral tear is called a Bankart tear, and is due to dislocation of the shoulder causing the tear.
