How do people break their collarbones?

A clavicle breaks when force or pressure causes it to snap. Common causes are:

• Collisions (trauma) when an arm is outstretched, like during skiing, hockey, football and other sports.
• Direct hits to the clavicle, such as in a car accident.
• Falls onto the clavicle or an extended arm.
• Passing through the birth canal for a baby.
