Jim,
Sorry to hear about the bone necros. I think the Pittsburgh hospital is the one doing the ECM experiments. Extra Cellular Matrix. I saw this on 60 minutes. It appears that new tissue can be grown around an artificial structure to replace and replicate the original tissue. They profiled a nice man with a new esophagus. He was all smiles. I'm not sure if bone is possible with this stuff but it might be worth asking the ENT about. Good luck to you on this journey.
