Seeking input

[Wally]

I am new to this group and am looking for input. I am a 61-year-old guy with DDD at L4/L5 and L5/S1 who is considering ADR. I have sent my images and data to three providers and received favorable responses. I am considering other providers and performing due diligence on my options. My pain levels are not currently extreme, thanks in part to facet joint injections a few months ago, but the pain is returning and I know that I need to do something structural for the longer term.

Obviously things can go wrong with any surgery or device, but I am interested in maximizing my chance for a positive outcome. I am interested in input about prosthetics, surgeons, etc. that might be useful. Thanks in advance for whatever you can tell me.

The implants which have been mentioned to me as options by the folks I have been in touch with are the Prodisc, M6, and possible the Aktiv.
