Collarbone Fractures
Introduction
Fracture of the collarbone (clavicle) is a break in the long bone that runs horizontally from the top of the breastbone (sternum) to the top of the shoulder blade (scapula). Collarbone fractures often occur after a fall on an outstretched arm or a shoulder or after a direct blow. These fractures cause pain, swelling, and sometimes a bulge or bump where the bone is broken. Doctors can usually identify collarbone fractures based on a physical examination, but x-rays are taken to pinpoint the fracture's location and determine the extent of the injury. Most collarbone fractures require only a sling, but some types of fractures require surgery. (See also Overview of Fractures .) Collarbone fractures are a common fracture, particularly among children. In some collarbone fractures, the broken pieces stay in place (called a nondisplaced fracture). Collarbone fractures often occur after a fall on an outstretched arm or a shoulder or after a direct blow. Most occur near the middle of the bone. The broken pieces of bone may stay in place (called a nondisplaced fracture) or be out of place (called a displaced fracture). In some collarbone fractures, the main ligaments that hold the collarbone to the shoulder bone are torn.
