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
• Newborn babies can break a clavicle passing through the birth canal

A risk factor is something that increases your chance of getting a disease, condition, or injury.

• Advancing age, because of the increased risk of falling
• Osteoporosis
• Certain congenital bone conditions
• Participating in contact sports
• Violence

Symptoms include:

• Pain, often severe
• Sagging shoulder, down and forward
• Inability to lift the arm because of pain
• A lump or visible deformity over the fracture site
• Tenderness and swelling of the affected area

The doctor will ask about your symptoms, physical activity, and how the injury occurred. The injured area will be examined.

Tests may include x-rays. This is a test that uses radiation to take a picture of structures inside the body, especially bones to look for a break.

Treatment will depend on the severity of the injury. Treatment involves:

• Putting the pieces of the bone back in position, which may sometimes require anesthesia and more rarely surgery
• Keeping the pieces together while the bone heals itself

To help prevent clavicle fractures:

• Do not put yourself at risk for trauma to the clavicle bone.
• Eat a diet rich in calcium and vitamin D.
• Build strong muscles to prevent falls and to stay active and agile.
