Robin,
Sorry to hear of your troubles. Wonder if part of the reason is due to the fact that the L2-L3 disk replacement has not been approved by the FDA, whereas L4-L5 and L5-S1 has. Mine is at L5-S1 and Dr McAfee's office said I didn't even need a discogram because it was so obvious as to where the trouble was.
In answer to "who has done the most ADR surgery in the US" I doubt if there's a scoreboard. I suspect that most of the clinical trials docs have done a similar amount. I really don't care if Dr McAfee has done 150 and a guy in TX has done 160, as long as they're good at it. I do know that Dr McAfee did the first
two-level replacement in the US and I have no doubt he's one of the best.
