A SLAP tear is an injury to the labrum of the shoulder, which is the ring of cartilage that surrounds the socket of the shoulder joint. Injuries to the superior labrum can be caused by acute trauma or by repetitive shoulder motion.| orthoinfo.aaos.org
In a shoulder dislocation, the head of the upper arm bone (humerus) may come either partially or completely out of the socket. To treat a dislocation, your doctor will place the ball of your upper arm bone back into the shoulder socket, a procedure called a "reduction."| orthoinfo.aaos.org
