injured shoulder is lower than the uninjured one. Usually the victim is unable to raise his arm above the level of his shoulder. The injured person may attempt to support the injured shoulder by holding the elbow of that side in his other hand; that is, in fact, a characteristic position assumed by a person with a broken collarbone. Since the collarbone lies near the surface of the skin, you may be able to detect the point of fracture by the deformity and localized pain and tenderness.

TREATMENT. When the fracture is open, stop the flow of blood and treat the wound before attempting to treat the fracture. You must bend the victim's arm on his injured side and place his forearm across the chest. The palm of his hand should be turned in, with the thumb pointing up. His hand should be raised about 4 inches above the level of his elbow. Support his forearm in this position by means of a wide sling.

Next, use a wide roller bandage (or any wide strip of cloth) to fasten the victim's arm to his body. Wrap the bandage several times around his body, and ensure it goes down over the hand so the arm is held close against his body.

Treat the victim for shock and obtain medical care as soon as possible.
