Clavicle Fracture (Broken Collarbone)

Picture
A broken collarbone is also known as a clavicle fracture. This is a very common fracture that occurs in people of all ages.

The clavicle is a long bone and most breaks occur in the middle of it. Occasionally, the bone will break where it attaches at the ribcage or shoulder blade.




Anatomy:
The collarbone (clavicle) is located between the ribcage (sternum) and the shoulder blade (scapula), and it connects the arm to the body.

The clavicle lies above several important nerves and blood vessels. However, these vital structures are rarely injured when the clavicle breaks, even though the bone ends can shift when they are fractured.

The clavicle is part of your shoulder and connects your ribcage to your arm.
Causes:
Clavicle fractures are often caused by a direct blow to the shoulder. This can happen during a fall onto the shoulder or a car collision. A fall onto an outstretched arm can also cause a clavicle fracture. In babies, these fractures can occur during the passage through the birth canal.

Symptoms:
Clavicle fractures can be very painful and may make it hard to move your arm. Additional symptoms include:
  • Sagging shoulder (down and forward)
  • Inability to lift the arm because of pain
  • A grinding sensation if an attempt is made to raise the arm
  • A deformity or "bump" over the break
  • Bruising, swelling, and/or tenderness over the collarbone.
Doctor Examination:
During the evaluation, your doctor will ask questions about the injury and how it occurred. After discussing the injury and your symptoms, your doctor will examine your shoulder.

There is usually an obvious deformity, or "bump," at the fracture site. Gentle pressure over the break will bring about pain. Although a fragment of bone rarely breaks through the skin, it may push the skin into a "tent" formation.

Your doctor will carefully examine your shoulder to make sure that no nerves or blood vessels were damaged.

In order to pinpoint the location and severity of the break, your doctor will order an x-ray. X-rays of the entire shoulder will often be done to check for additional injuries. If other bones are broken, your doctor may order a computed tomography (CT or CAT) scan to see the fractures in better detail.

Treatment:

Nonsurgical Treatment
If the broken ends of the bones have not shifted out of place and line up correctly, you may not need surgery. Broken collarbones can heal without surgery.

Arm Support A simple arm sling or figure-of-eight wrap is usually used for comfort immediately after the break. These are worn to support your arm and help keep it in position while it heals.

Medication Pain medication, including acetaminophen, can help relieve pain as the fracture heals.

Physical Therapy While you are wearing the sling, you will likely lose muscle strength in your shoulder. Once your bone begins to heal, the pain will decrease and your doctor may start gentle shoulder and elbow exercises. These exercises will help prevent stiffness and weakness. More strenuous exercises can gradually be started once the fracture is completely healed.

Complications The fracture can move out of place before it heals. It is important to follow up with your doctor as scheduled to make sure the bone stays in position.

If the fracture fragments do move out of place and the bones heal in that position, it is called a "malunion." Treatment for this is determined by how far out of place the bones are and how much this affects your arm movement.

A large bump over the fracture site may develop as the fracture heals. This usually gets smaller over time, but a small bump may remain permanently.

Surgical Treatment:
If your bones are out of place (displaced), your doctor may recommend surgery. Surgery can align the bones exactly and hold them in good position while they heal. This can improve shoulder strength when you have recovered.

This a good article giving a quick insight into Collar bone fracture. Unfortunately, I met with a free fall on hard road because of icy road. Mutiple fractures have occured and Doctors advised me after a X-ray, to wear sling belt. My question is how long I've to wear that, as, by today, it exactly 2 months that I met with accident. My pain has considerably reduced, but still I can't sleep on that side, as, it pains a lot. But I've started doing regular exercises to the level best I can do, without hurting myself. Doctors have advised me phyisio therapy which is very expesnive here. Can you please advice me ? Thanks in advance
