Prodisc ADR fusing and not moving

[energyofhope]

I've had one Prodisc-L in my low back fuse about 18 months after insertion, and recently one Prodisc-C in my neck stopped moving and there is eveidence of fusion from the facets at that level. I suspect that my worsening neck pain is related to this latest "finding" on CT.

Has anyone here experienced a similar phenomenon with ADR fusing? If so, has this created a problem with pain, and what was your solution? Did you need to have a decompression surgery leaving ADR in place, or a complete removal of the prosthesis with "standard" fusion?

Thank you all!
