Michelle, I can only tell you what I know about ProDisc-L.
It comes in 2 different foot prints (maybe 3, from what Dr. Bertagnoli was telling me), medium and large (Dr. B. said he could also use size small).
There are 3 different heights, 10, 12 and 14 mm.
There are 2 Lordotic angles, 6 degrees and 11 degrees.
That gives 12 (or 18) anatomical implant combinations, to best match a patients anatomy.
I don't know about other disc brands, but the ProDisc does come in a variety of sizes.
