What are the different types of bone fractures?
Simple, Compund, Comminuted, Depressed, Impacted, Spiral, Greenstick
Describe simple fractures…
Regular break, clean, one full break
…compound fractures
One break that breaks through the skin
….comminuted fractures
Crumbled, shattered break
… Depressed fractures
Only applies to flatbone. Outer compact bone is pushed in
… Impacted fractures
Two bones get their ends broken off
… Spiral fractures
Bone is twisted
… And Greenstick fractures?
Bones don’t completely break.
Steps of bone healing
1: cartilage bridge gets formed
2: osteoblasts come in and turn cartilage into bone
What is the epiphyseal plate?
The growth plate. It is cartilage that has yet to turn into bone
