Introduction

Broken collarbone
Broken collarbone

A broken collarbone, or fractured clavicle, is a common injury. It usually happens after a fall or a blow to the shoulder.

It takes about six to eight weeks to heal in adults, and three to six weeks in children.

The collarbone is a long slender bone that runs from the breastbone to each shoulder.

You can feel it at the top of your chest, just below your neck. Tough bands of tissue (ligaments) connect the collarbone to the breastbone and shoulder blades.

When to get medical help
 
See your GP straight away if you've injured your collarbone. If your GP thinks it's fractured, they'll refer you for an X-ray to confirm the injury and have it treated with a sling and brace.

If you can't see your GP or if the injury is severe – for example, the bone is poking through the skin or the pain is unbearable – go straight to your nearest hospital accident and emergency (A&E) department.

What you should do

While you wait to see a doctor, stabilise the arm by using a towel as a sling (this goes under the forearm and then around the neck). Try to move the arm as little as possible.

Over-the-counter painkillers, such as paracetamol or ibuprofen, can help reduce the pain – aspirin shouldn't be given to children aged under 16.

Holding an ice pack to the injured area can also help reduce the pain and swelling. A bag of frozen peas wrapped in a tea towel works well. Avoid applying ice directly to the skin as it can burn.

Symptoms of a broken collarbone

A cracked or broken collarbone will be very painful. There may also be:

  • swelling or tenderness around the injured area
  • bruising to the skin
  • bleeding if the bone has damaged the tissue and skin (this is rare)
  • numbness or pins and needles if nerves in the arm are injured

Your shoulder may be slumped downwards and forwards under the weight of the arm, as the broken collarbone is no longer providing support.

There may have been a snapping or grinding noise when your collarbone broke. In severe cases, one end of the bone may poke through the skin.

Treating a broken collarbone

Most broken collarbones are left to heal naturally using a simple triangular sling to support the arm and hold the bones together in their normal positions.

The sling is usually fitted in hospital after an X-ray has confirmed the collarbone is broken. You'll be given painkillers to relieve the pain. 

Surgery under a general anaesthetic is only needed if the injury is severe – for example, where the bone has broken through the skin – or if the bones have failed to line up and are overlapping significantly.

Several techniques can be used to repair the collarbone. Fixing the break with a plate and screws is the most common method. Your surgeon will explain the technique they'll be using, and the advantages and disadvantages of this method.

Being discharged

You may need to stay in hospital overnight, depending on the extent of the injury.

Before you're discharged, you may see a physiotherapist, who can show you some gentle arm and shoulder exercises to do at home with your arm out of its sling. These will help reduce stiffness, relieve some of the pain, and strengthen your shoulder muscles.

Follow-up

You'll probably need to go back to the hospital outpatient department about one week later to make sure your collarbone is healing properly. See your GP if you have any concerns before this appointment.

You should go back to the A&E department if you notice any weakness developing in your arm or hand, or if your pain suddenly becomes worse.

How long does it take to heal?

In adults, it usually takes about six to eight weeks for a broken collarbone to heal, although it can take longer. In children, it usually takes about three to six weeks to heal.

However, it will take at least the same period again to restore full strength to your shoulder.

While the fracture heals, a lump may develop along the collarbone. This is normal and often improves over the following months. Occasionally, the fracture doesn't heal (non-union) and you may need to have surgery. This should be discussed with your surgeon.

Recovery advice

You may find the following advice helpful while recovering from a broken collarbone:

  • use extra pillows at night to keep yourself more upright if you find sleeping uncomfortable
  • use ice packs and painkillers if pain and swelling continues while your arm is in a sling
  • try to move your elbow, hand and fingers regularly as soon as it's comfortable to do so
  • when you think the fracture has started to heal, try removing the sling for short periods at a time if it's not too painful
  • avoid contact sports for at least 10 to 12 weeks after the injury – your doctor will tell you when you can go back to work and resume normal activities

It's important to let your arm hang freely. Avoid resting your arms and elbows on chairs, tables, pillows or inside the sleeves of clothes until your collarbone has healed.
