Sherry, I believe you are correct with respect to the Prestige Disc. It requires screws in the vertebrae above and below the disc. If you were to do multi-level, it would require two sets of discs with screws on at least one of the vertebrae which would make it unstable.
Take a look at this link: https://www.medtronic.com/patients/c...vice/index.htm
Good luck with your surgery!! It will be done before you know it!!
