Hi! Thanks for helpful information! I'm new to even finding about "ADR". I recently saw a really good Spine repair discussion (forum) from "Texas Back Institute" on Artificial Disc Replacement (cervical and lumbar), it's 2 biggest benefits of pain reduction and better movement, plus regular Spinal Fusion (sometimes, not always, better for a few situations). The 3 doctors/surgeons were Guyer, Shellock, and Blumenthal. All stressed the importance & value of the surgeons' experience for getting the best choice for each person's situation and surgeons expertise. They also mentioned a few ADR limiting factors. I don't know what financial help there is accepted or available, or the costs. But not finding many other leads (for me) near Chicago, I plan to go back to "TBI" & get some more "ADR" info there.
