Symptoms of a broken collarbone include:

• Pain that increases when moving the shoulder.
• Swelling, tenderness or bruising.
• Skin over the break might look like a tent when gently pinched.
• A bump on or near the shoulder.
• A grinding or crackling sound when moving the shoulder.
• Stiffness or not being able to move the shoulder.

Newborns often will not move their arm for days after breaking the collarbone during birth and will cry if someone moves the arm.

When to see a doctor

If you notice symptoms of a broken collarbone or enough pain to prevent using the arm as usual, see a health care provider right away. Waiting to be treated can lead to poor healing.

Common causes of a broken collarbone include:

• Falls, such as falling onto the shoulder or onto an outstretched arm.
• Sports injuries, such as a direct blow to the shoulder on the field, rink or court.
• Traffic accidents, from a car, motorcycle or bike crash.
• Birth injury, usually from a difficult vaginal birth.

Teenagers and children are at higher risk of a broken collarbone than are adults. The risk goes down after age 20. Then it rises again in older people as they lose bone strength with age.

Most broken collarbones heal without difficulty. Complications, when they occur, might include:

• Nerve or blood vessel injury. Rarely, the jagged ends of a broken collarbone may injure nearby nerves and blood vessels. Seek immediate medical attention for numbness or coldness in an arm or hand.
• Poor or slow healing. A badly broken collarbone might heal slowly or not all the way. Poor joining of the bones during healing can shorten the bone.
• A lump in the bone. As part of the healing process, the place where the bone knits together forms a bony lump. The lump is easy to see because it's close to the skin. Most lumps disappear over time, but not all.
• Osteoarthritis. A fracture that involves the joints that connect the collarbone to the shoulder blade or the breastbone might increase the risk of later developing arthritis in that joint.

During the physical exam, a health care provider inspects the area for tenderness, swelling or an open wound. X-rays show where the break is, how bad it is and whether the joints are injured. A CT scan might give more-detailed images.

For healing, any broken bone must be kept still. People who have a broken collarbone usually need to wear a sling. Bone healing usually takes 3 to 6 weeks for children and 6 to 12 weeks for adults.

A newborn's collarbone that breaks during delivery typically heals in about two weeks with only pain control and careful handling of the baby.

Medicines

A pain medicine that you can buy without a prescription might be all that's needed to ease pain. Some people might need a prescription medicine with a narcotic for a few days. Because narcotics can be habit-forming, it's important to use them for only a short time and only as directed by a health care provider.

Therapy

Exercises to restore movement begin soon after treatment starts. It's usually important to begin moving to lessen stiffness. Later, other exercises or physical therapy can help the joint move better and build muscle strength.

Surgery

Surgery might be needed if the collarbone has broken through the skin, is out of place or is in several pieces. Broken collarbone surgery usually includes using plates, screws or rods to hold the bone in place while it heals. Surgical complications are rare but can include infection.

Children and teenagers younger than 16 rarely need surgery because they heal more quickly than adults do.

Applying ice to the area for 20 to 30 minutes every few hours during the first 2 to 3 days after a collarbone break can help control pain and swelling.

Depending on how bad the break is, your health care provider or a provider in the emergency room might recommend a surgeon who treats bone injuries, also called an orthopedic surgeon.

What you can do

It might be helpful to write a list that includes:

• Details about symptoms, what caused the injury and when it happened.
• Information about past medical problems.
• All medicines, vitamins and dietary supplements you take, including doses.
• Questions to ask the health care provider.

What to expect from your doctor

Your provider might ask:

• Have you broken a bone before?
• Have you been told you have weakened bones?
