Forequarter and Shoulder Amputation
Shoulder disarticulation is when the entire arm is removed, but the shoulder blade (scapula) and collar bone (clavicle) are still present. In the forequarter amputation the scapula and clavicle are also removed. The major difference between these two levels is that some shoulder movement is retained with a shoulder disarticulation. The forequarter amputation also makes the body appear asymmetrical as the shoulder width is reduced significantly.
