Ask for a copy of your MRI when you have it taken. Send a copy up to Otto or some other doctors. When I was in physical there was another guy that had a disk replacement, from a donor, he was up and round within two days of surgery. Based on the description of my pain my doc had me go for an MRI even before he saw me. He didn't even bother with an X-ray. I believe the replacement was done at Robert Wood Johnson here in NJ. Maybe Otto can get you more info on it. My doc also told me if I keep going the way I have been that I'll be back for fusion or replacement. At least I have time on my side since every year the procedures get better. He wasn't happy when I got back into the boat.
Find a good doctor no matter where you have to go. Check their background and find the best.
For example here is my surgeon's. He is the chief of Spinal Surgery at Jersey Shore Medical Center, Neptune, NJ. His expertise includes degenerative and congential disorders of the spine, microsurgery, scoliosis, spinal trauma, and reconstructive surgery. Dr. Lospinuso completed two prestigious fellowships in scoliosis and spinal surgery at the Hospital for Special Surgery, Cornell University Medical Center, New York.
I was lucky since he was recommended by a pediatric orthopedist as the only person that would cut him. Get second opinions even if you have to leave the state.
As for Chiros, if I would have gone to one I would now be sitting in a wheel chair. Any manipulation would have severed my nerv.
