Thank you dale
 

thank you for telling me what the adr is. i did some research on the adr and it turns out that the dr i have actually participated in the clinical trial that led to FDA approval of the first artificial disc, a metal-and-plastic device. so i am hoping that he is thinking that i would better benift from an alif rather than an adr but i will ask the next time i see him once again thank you for answering my question.

do it do it do it!
 

i am a participant and was one of the first 2 levels here in so cali to get the prodisc implants:D, it has been a life altering experience for me! finally no more back pain!!
if you are right for the surgery and have faith in your surgeon, go for it!
