I just saw my feldenkrais person, and told her about the recommendations and my worries. She had referrals to people who specialize in bone "Bones for Life" a subgroup of practitioners with her training, and a machine the WBV which is supposed to stimulate bone growth.

But the most interesting comment she had was why get surgery like they suggest when I could just continue to wear a brace? If the brace works from the outside, why not use it for life?

This is a good thought. I'm going to stay with it for a bit.
