A clavicle fracture is a break in the clavicle bone (also called the collarbone). It connects the sternum (breastplate) to the shoulder.

The clavicle can fracture in three different places:

  • Middle third—the middle portion of the clavicle, which is the most common site for a clavicle fracture
  • Distal third—the end of the clavicle connecting to the shoulder
  • Medial third—the end of the clavicle connecting to the sternum

A clavicle fracture is caused by trauma to the clavicle bone. The trauma is usually caused by:

  • Direct blow to the clavicle
  • Falling on an outstretched arm or on the point of the shoulder
  • Newborn babies can break a clavicle passing through the birth canal
