appolinaria-
Anytime they can go in and not fuse, and make the smallest incision possible, that is the best thing to do.
I've heard a lot of good things about Dr. Jho (
www.drjho.com), maybe one negative. I don't know where you are located, but I think he's in Pittsburgh, PA. I had my (good) surgeries done at Duke University Hospital. Sometimes teaching hospitals are good to look at.
Good luck to your husband.
