Shoulder Separation

A shoulder separation is not truly an injury to the shoulder joint. The injury actually involves the AC joint. The AC joint is where the collarbone meets the shoulder blade. The most common cause for a separation of the AC joint is from a fall directly onto the shoulder. The fall injures the ligaments that surround and stabilize the AC joint. If the force is severe enough, the ligaments attaching to the underside of the clavicle are torn. This causes the "separation" of the collarbone and wing bone. The wing bone actually moves downward from the weight of the arm. This creates a "bump" or bulge above the shoulder. The injury can range from a little change in configuration with mild pain, to quite deforming and very painful.
