Have you read the informative site provided?
If you haven't been able to find it, here it is:

There is a small segment within this info site that addresses what you may be referring to, I'm not sure.
Given the fact that you've got '5' things wrong with your back, there is NO way we can give you advice that only a professional can give.
We can offer you support and links to informative sites, but we can not zero in on whether this implant is right for you.
If your Dr is telling you that this procedure hasn't been FDA approved for YOUR case management, then take HIS word as gold, not ours.
All we can do is provide you with our experiences, and the LINKS to informative sites.
PLEASE READ these links!! THEN ask (for support) We cannot give medical advice.
