Simple (closed) – partial or complete break, bones don’t break the skin
Compound (open) – most serious, ends are torn apart and the bone is exposed to infection.
How does a bone fracture heal?
1st Step – swelling around the break, blood supply is increased
2nd Step – Periosteum makes new cells and new minerals
