How was the diagnosis confirmed that your Prodisc-C had migrated forward? The only way that I know would be an A/P and Lateral Xray confirmation that was compared with the same X-rays when the disc was placed. What you would see at that point would be the CoCr plate of the disc sticking out in front of the spine. It is possible (and unfortunately a potential weakness of the keeled design) as the product is held in place by bony ingrowth to the superior and inferior aspect of the plate. The advantage of this is no screws, however the disadvantage appears to be that the device can "slide" in the keel space if one was jarred enough prior to it completely healing into place.

Rgardless, if you have x-ray confirmation, then I would agree that you may be looking at a revision. I recently had my Prodisc-C done at UCH Carrolwood with Dr. Billys (Florida Orthopaedic). I had several physician reviews of my MRI and all confirmed my C6-C7 herniation. However, I had three local Tampa Bay based opinions and 2 of three said ACF over ADR. I did some research with some local spine reps and was lead to Dr. Billys. He suggested ADR over ACF, based largely on my age and activity level. He has been nothing but professional and great to deal with. I am 3 weeks post-op today and am now in physical therapy 3x per week. I want to do everything that I can to avoid future issues and realize that this may seem like more of an agressive path this early, however as a medical device rep (non-spinal related) and former surgical rep, I tend to side with agressive therapy choices.

Since you make a comment about the Tampa area, I would suggest a visit to Dr. Billys (unless he is the one who did your original case and you want to look elsewhere). A local spine sales rep suggested to me that there is also a high volume ADR operator in Orlando, although I do not know the name off hand, maybe someone on this board can help. After a few visits with Dr. Billys, I felt comfortable with his knowlege and experience as an enroller in several ADR studies (even offering to assist with getting me into the Discover study, or a new disc on disc study). He has also spoken on ADRs and ADR/ACF combonation procedures (which may also be an option based on your symptoms, assuming you want BCBS to financially support the procedure) at regional spine meetings.

Regardless, I wish you all the best of luck with alleviating your pain and finding a suitable solution for you... Feel free to PM me if you wish.
