I read an article you wrote where you commented on having successfully removed Pro-Disc C from an anterior approach without too much difficulty. Have you had the same success removing Mobi-c? Sadly I have both and the Mobi-c has been a nightmare, while the Prodisc C is holding up. There is a lot of hype (And pressure/Marketing) pushing these devices, but little in the way of patient counseling about what happens if they do not work out. Thank you.
