I'm afraid I can't provide the help you're asking for.
I’m not a doctor, but I think if you break a bone, someone usually needs to put it back in place and cast it.  Or if you break a lot of bones at once, they might call it a “compound fracture” and put a cage around the bones so they can grow back in the right shape.
