Is there a disc less prone to injure facets? Keel vs. non?

[ans]

Hi Folks,

Is there? I hear good things about the Active-L but dunno if it's for public consumption yet.

Also, if one needs a revision, does it make sense to get a non-keeled on versus a keeled one?

The reason I ask is b/c my MRIs show "moderate" facet damage and even if my facet injections don't help me I'd wonder about facet compromise w/ADR down the line.

Thanks and be well. - Allan
