CONDITION
The collarbone (clavicle) is an S-shaped
bone on the front of your body that attaches your shoulder
bones to your breastbone. When a collarbone is broken
(fractured), it usually breaks in the middle (Figure
1), but fractures sometimes occur on either end. Some
collarbone fractures require surgery but most will heal
without it.

CAUSES
Most clavicle fractures are caused by one
of three things:
- falling on an outstretched hand
where force is passed up through the arm to the
collarbone
- falling onto the outside of the
shoulder where force is passed through the shoulder to
the collarbone
- direct impact or force to the
clavicle.
Clavicle fractures can also happen to
babies as they move through the birth canal during
childbirth.
SYMPTOMS AND SIGNS
- You will have pain over the broken
bone.
- If the fracture is in the middle of
the collarbone (and most are), you will notice a lump or
deformity sticking up where the bones are broken.
- If the fracture is on the shoulder
end of your collarbone, you will usually not notice a
lump but you will have swelling over the front of your
shoulder and it will hurt to reach across your body.
- If the fracture is near the chest
end of your collarbone, you will have pain where your
collarbone joins with your breastbone. There will
sometimes be a lump or depression at the joint, depending
on whether the end of collarbone is pushed out or in, and
it will hurt to move your arm or shoulder.
- If the breastbone end of the
collarbone is pushed too far backward (dislocated), it
can injure your airway (the tube that goes from your
mouth to your lungs), major arteries and/or veins (blood
vessels that carry blood to and from your heart to your
body) and nerves (the body’s “electric
wires” that control body processes and movements).
These injuries can be life-threatening and may cause the
following symptoms:
- If your airway is compressed,
you may feel short of breath, have throat tightness
or make wheezing sounds.
- If you have a blood vessel
injury, your arm may be pale or grey, you may have
decreased or absent pulse in the arm on the side of
the fracture or swelling in that arm.
- If you have a nerve injury,
your voice may be hoarse and you may have problems
swallowing or feel like you are choking.
- You will have pain when you try to
move your shoulder or lift your arm because this moves
the fractured collarbone.
- You will notice swelling over the
fracture and may have some bruising in the area.
- You may find it most comfortable to
hold your arm across your chest to minimize movement of
the broken collarbone.
