Healing - Fractures

healing process

Osteogenic bone stem cells
Osteoblasts bone-making cells
Osteoclasts bone destroying (cutting) cells
Osteocytes mature bone cells
What happens during week 1? A hematoma (blood clot) forms to stop bleeding
What happens during weeks 2-3? A soft callus (fibrocartilage) forms to bridge the broken pieces together and new blood vessels grow back into broken end
What happens during weeks 4-16? Osteoblasts form a hard callus (bone) forms to repair break
Why are the weeks 4-16 dangerous? Dangerous because if you break your bone again it won’t break “where it is supposed to” and could cause more damage to the body.
What happens during weeks 17-52? Osteoclasts break down hard callus to bring the bone back to its original shape
