I don't know how big the broken portion is. Maybe if it's not too large you could graft it back together. The easiest thing would probably be to root the top and allow the bottom to send out new branches. It will take a while for each piece to regenerate, especially because they are now going into dormancy.

Sorry to hear about your damage. I had a good amount of storm damage also. At least I didn't lose many branches, just most of my inflos : (

The grafting is probably the best idea.
