So I'm allergic to nickel and my neurosurgeon ditched the idea of using the titanium plates (since they are mixed with a bit of nickel) my only choices are now using tantalum or a cadaver bone. He said he wasn't sure if he could acquire the tantalum cages though. Cadaver bone has a 15-20% non-fusion rate that follows and I'd have to be in a hard collar for 3 months (initially 6 weeks if using a cage). So is tantalum something that is used in the U.S that can be acquired? Should I push the surgery date to wait for the tantalum or just suffer through the 3 months of hard collar with a earlier surgery date with the cadaver bone while risking the non-fusion rates? Even if tantalum is acquired, I figure I would have to get tested for it, but I heard it was a bio-inert and there were no reports of tantalum allergies.
