Q

why is it better to use someone’s own bone when using a bone graft to repair a fracture, rather than using bone from the bone bank?

Q

what is the pathology behind acute osteomyelitis?

A

inflammation results in increased pressure.
pus is released into medulla/periosteum.
pus in joint causes bone destruction and reformation.
