Break Points for Bones

Hi,
I'm trying to do some research on breaking points for different bones, but I'm not sure where to look. Can anyone point me in the right direction? Also, are there different measurements for different levels of severity?

For example: x psi is a fracture, y psi is a break, z is (something worse?) ?

Any help is great! Thank you in advance!
