Ouch, I hope you have a speedy recovery. Getting around on crutches makes for very strong hands and arms once you get off of them. Make sure they are properly adjusted for you.
Okay, traveling through TSA checkpoints. Here is what TSA says about that.

If you don't have any metal under your bandage (staples) then you shouldn't have any problems. The operative word is shouldn't. Since you're new on crutches, when you get to the airport get on board a wheelchair ASAP. You don't want to further injure yourself by falling over. That will get you boarded before anyone else. During checkin make sure you get a seat that allows you maximum comfort.
Take care of yourself and don't let TSA ride roughshod over you.
