Clavicle fractures occur as a result of direct trauma to the shoulder region or direct contact with the clavicle. The clavilce is the first bone in the body to ossify and serves as the only bony connection between the arm and the trunk. This may be a reason why it is a good target area as it can prevent subjects from using their arms to their full extent. EMS must observe for signs of respiratory complications as some clavicle fractures may involve the lungs. [19]
A downward strike to the clavicle also has the potential to become a life threatening injury, if stuck with enough force. The subclavian artery runs underneath the collarbone and if struck forcefully enough a fragment of the bone or the bone itself can cause a tear in the artery.
