What Is It?
When a bone breaks or cracks, the injury is called a fracture. In the collarbone (clavicle), fractures can happen in three separate areas:
The collarbone is one of the most common fractures. In most collarbone fractures, the ends of the fractured bone do not move apart widely, and the area of tissue damage involves only the collarbone. In rare cases, a sharp portion of the fractured bone either will pierce the surface skin (an open fracture), or cut into one of the large nerves or blood vessels that travel through the shoulder. In severe impact injuries, it is also possible for a portion of the fractured collarbone to penetrate the upper part the lung, causing serious breathing problems.
