prestige or Pro Disc advice

[Bill1961]

Anyone have opinions on which FDA disk is more desirable Pro Disc or Prestige? My view is that the Prestige is a better option. If there is a problem revision is easy, four screws. The Prodisc has a center keel and the remote chance of vertebrae fracture or if revision was required you could could lose a lot of vertebrae from a cleave effect.

If someone has one I would appreciate your view.

Thanks.
