The sternum is a flat bone located in front of the thorax, in the midline of the body (in the center). It is articulated on each side with the first seven ribs as well as with the clavicles in which it forms the sternoclavicular joint. Located under the skin, it is in front of a large part of the heart.
The sternum is made of the fusion of three bony pieces:
It consists of three parts:
Manubrium: is the most superior portion and has a quadrangular shape.
Body: is longer, thinner and flatter than manubrium.
Xiphoid process: is the smallest of the three parts. In the young, it is a cartilaginous piece that ossifies throughout the development.
