Start working out the bicep lightly. Doing some light dumbell curls a couple times a week and just getting it back use to being used and put under some kind of load. I'm sure it will get fatigued quickly during the sessions and the strength won't be much but don't rush it. Work your other body parts as you normally would, but be carefull to take it easy on things that involve the bicep such as doing movements for back. After the muscle gets healthy and used to being worked again, you will be suprised how quickly the size comes back to it. Also, there is a section to this board called "weight training/ weight lifting" and you'd probably find alot more answers there and I'm sure there are some guys on here who suffered the same injury and rebounded strong from it and will be happy to give you some tips and advice about what worked for them. Good luck.
