hi jjames,
sorry for the battle w/FDA approvals.
i would recommend contacting Synthes, the manufacturers of Prodisc, if you have not already re: anticipated FDA approval of two-level lumbar Prodisc,
http://www.synthes.com/html/. I've spoken w/them pre- and post-op and they are very helpful.
Dr. Yue should be able to give you the inside scoop as well. Is Dr. Yue still participating in the Activ-L trial? If so, sometimes doctors in the trials can petition the FDA for a compassionate exemption (or something like that) for two-level cases.
Would your insurance pay for one-level Prodisc as part of a hybrid operation (w/a fusion)?
if i remember correctly, there is a guy on this forum that recently had a 4-level lumbar Prodisc w/Dr. Yue... i can't remember his name, but i'm sure Dr. Yue would... wonder how he made that happen?!
Best of luck,
Liz
