There are, broadly speaking, two types of bone injuries that concern a first-aider. The one is a fracture, the other a dislocation.
When a bone injury occurs, it is not just the bone that is affected; the surrounding tissue and their functions are also affected.
FRACTURES
A fracture is a break or crack in a bone. Adult bones require considerable force to break, but children's bones are more flexible and supple. These young bones sometimes split instead of breaking. This is called a greenstick fracture.
The elderly's bones aren't as resilient as they used to be and are prone to breaking more easily. The elderly usually break the head of the femur (the upper leg bone) where it connects with the hip.
A fracture where the bone protrudes through the skin is called an open fracture. A fracture without a surface wound is a closed fracture.
Fractures are caused by either direct or indirect force. Direct force is a blow that affects the bone under its impact, causing it to break. Indirect force is when the impact caused a fracture at a distant point, e.g. a twisting action in the ankle breaks a bone in the lower leg or, by falling on outstretched arms you break the collar bone.
Priorities:
If the casualty is unconscious, ensure that the casualty's airway is open, that the casualty is breathing and that there is a carotid pulse.
Control bleeding, but do not apply direct pressure. Press firmly next to the fracture, this is called indirect pressure. Never touch the bone, because this could lead to severe infection.
Immobilize the fracture.
You will notice:
Discomfort around the fracture.
You may notice:
Swelling and bruising.
Pain.
Shortening of the affected limb.
Unusual shape to the affected area.
A grating sound if the bone ends move.
Difficulty and discomfort in movement.
With fractures of the small bones in the hands and feet, there may be normal movement accompanied by severe discomfort, but little visible signs of injury.
Note:
With fractures of bones that protect the body's organs (skull, ribs, pelvis etc.) always suspect underlying organ injuries.
DISLOCATIONS
Following a strong wrenching force or a violent contraction of muscles, it is possible for a bone to become displaced at a joint. It most commonly happens at the shoulder, finger, thumb and jaw.
You will notice:
Swelling.
Discomfort.
You may notice:
Pain.
An unusual shape to the affected joint.
Bruising. Treatment:
Do not try to force the dislocated part back in its socket.
Put a cold compress on the affected area.
Seek medical attention. FRACTURES
