Ranier CAdisc (Cervical / Lumbar Artificial Disc) Now that the Ranier CAdisc-C and CAdisc-L (Compliant Artificial Disc for cervical and lumbar) is being used in trails I wanted to post in the case anyone has any feedback or experience with this new artificial disc. Apparently it's being manufactured, tried and only offered in UK thus far. My point of interest in this concept is the reversibility of it. It seems by it's very design it could easily explant (easily be removed) allowing for far less risk should the disc need to be removed (revision) for fusion. At the same time, by it's design, it's hard to tell if it will provide ample grip in preventing migration.

No major treatments so far aside from exercising and core strengthening best I can.

re: Ranier CAdisc (Cervical / Lumbar Artificial Disc) 
I emailed Ranier in early June just out of curiosity about US availability. Here's the reply from Louisa at Ranier. A very nice woman:
Hello,
Just curious to know when/if your CAdisc L and C will one day be available to US patients or is that still unknown?
Thanks for any help.Dear Carson
At this time it is still unknown, by the end of the year CAdisc - L will be available within Europe. I suggest you keep a close eye on our website to see when things may change.
Best wishes
