My friend just had this procedure and it did not work for him. I hope he wont be mad that I am commenting about him so I wont mention his name. But he is still in pain and It doesn't seem that North American Spine wants to take care of him here. I am not sure what they can do to fix anything though. It cost him all the money he could come up with and I really hope that these guys do everything in there power to fix him or make it right.
