A clavicle fracture, more commonly known as a broken collarbone, frequently occurs in children, adolescents and young adults. The clavicle is the bone that joins the shoulder blade to the upper part of the breastbone and it is not fully hardened until around the age of twenty, which is why children and adolescents are more at risk. Older people are also more prone to clavicle fractures as the bones become weaker with age. Babies may also fracture a collarbone during the birthing process. If you suspect you have fractured your clavicle, you should see a doctor immediately. Although fractures normally heal well, if they are not diagnosed and treated appropriately, healing may be incomplete and surgery may be needed to realign the broken bone.
