Often branches can be saved with tape and support, there's also some plant glues out there. Next time i would try doing a supercrop of the long branches when they get too stiff and woody, less chance of a big break. If you're still in the veg period i wouldn't worry too much and just let her grow through it. And hopefully the branch will heal up for you, it'll be obvious fairly quick if she won't, within a few days you'll see if the leaves are limp and dying off.
