During shoulder arthroscopy, your surgeon inserts a small camera, called an arthroscope, into your shoulder joint. The camera displays pictures on a video monitor, and your surgeon uses these images to guide miniature surgical instruments.| orthoinfo.aaos.org
Shoulder fractures most often involve the clavicle (collarbone), proximal humerus (top of the upper arm bone), or the scapula (shoulder blade). Shoulder dislocations can involve any of the three different joints that make up the shoulder.| 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
Shoulder instability occurs when the head of the upper arm bone is forced out of the shoulder socket. Once a shoulder has dislocated, it is vulnerable to repeat episodes. When the shoulder slips out of place repeatedly, it is called chronic shoulder instability.| orthoinfo.aaos.org
