How do I recognise and treat a fracture/broken bone?

Bones can break as a result of direct or indirect force (such as twisting).
What are the signs and symptoms of a broken bone?
(The signs and symptoms can be identical to dislocations)
The signs and symptoms of a fracture or broken bone include:
Pain or tenderness
Swelling or bruising
Unnatural movement
Loss of power and inability to bear weight
Lumps or dips in the skin – this may be because the bone is overlapping or out of place
Deformity – it is worth comparing to the other side of the body to notice this
Crepitus – this is a noise made by two bones rubbing against each other when the injured area is moved.
How is a fracture/broken bone treated?
The initial treatment by the first aider should be as follows:
Immobilise the injury (for example, a sling)
Gently cover any exposed bone with a sterile dressing
Reassure the casualty and treat for shock
Send the casualty to the hospital for an X-Ray and further treatment.
