Okay,
first of all, stop the "with my luck crap" I am a civilian, not a doctor. I'm sure yours knows what he's doing, and if your fiance who works in the same hospital says he's good, TRUST HER! You need to have confidence in your doctor, and a positive attitude going into surgery.
As for the cadaever. It's not a cadaever disc. It is ground up cadeaver bone that is milled into the shape of a disc. It acts the same way a cage does, the only difference is that all the bones, my vertabrae and cadaever fuse into on solid mass of bone eventually. Perhaps that is not the best approach since you have a collapsed vertabrae and bad disk. My problems pre surgery were not the same.
I know this is scary, but you've got your whole life ahead of you, and a wife that's a nurse to help you after surgery. Dude, you're lucky! Now, quit whining and go plan your wedding
