The<unk> has a body, neck, and spine; any of these may be fractured. The most commonly injured areas are the<unk>  body, spine, neck, and glenoid rim; the<unk>  body or neck is injured in about 80% of cases. Fractures that occur in the body may be vertical, horizontal, or comminuted (involving multiple fragments). Those that occur in the neck are usually parallel to the glenoid fossa. When they occur in the glenoid fossa, fractures are usually small chips out of the bone or extensions of fractures occurring in the<unk>  neck. The<unk> is protected from the front by the ribcage and chest, and from the back it is protected by a thick layer of muscles. Also, the<unk> is able to move, so traumatic forces exerted on it are dissipated, not absorbed by the bone. Thus a large amount of force is required to fracture it.
