As far as speeding up the bone healing process, have you asked your ortho about a bone stimulator device?
I had a bad collarbone break, and after 8 weeks there wasn't much healing. The doc put me on a bone stimulator, and she was amazed at the results after wearing the stimulator for 5 weeks.
Check into it. Athletes wear them to get back in the game as soon as possible. I believe that it definitely reduced my recovery time.
Or maybe your type of break takes a long time regardless...
