Scapular Fracture - Anatomy

Anatomy

The scapula has a body, neck, and spine; any of these may be fractured. The most commonly injured areas are the scapular body, spine, neck, and glenoid rim; the scapular 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 scapular neck.

The scapula 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 scapula 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.

Famous quotes containing the word anatomy:

    Man is a shrewd inventor, and is ever taking the hint of a new machine from his own structure, adapting some secret of his own anatomy in iron, wood, and leather, to some required function in the work of the world.
    Ralph Waldo Emerson (1803–1882)

    But a man must keep an eye on his servants, if he would not have them rule him. Man is a shrewd inventor, and is ever taking the hint of a new machine from his own structure, adapting some secret of his own anatomy in iron, wood, and leather, to some required function in the work of the world. But it is found that the machine unmans the user. What he gains in making cloth, he loses in general power.
    Ralph Waldo Emerson (1803–1882)

    I love to see, when leaves depart,
    The clear anatomy arrive,
    Roy Campbell (1902–1957)
