ell, seeing as that news was old apparently I'll say something that is relatively new. medtronic has recently gotten FDA approval of a new spine graphting(sp?) method. The old spine graphting method required 2 operations one to shave bone from your hip and another one to put that bone in your spine where it will eventually grow back. This new thing only requires one surgery, they put a sponge in your spine. The sponge by itself isn't very interesting, but it is soaked in genetically engineered proteins, which promote growth of bones. if this is old please feel free to insult me.
