Be on the safe side and ask the surgeon to give you one when you have the surgery. There is little chance you would need it but a 8.5" x 11" piece of paper or a scribbled note on a prescription pad is worth taking, if only for the peace of mind.

Be prepared at airport security also, if you are traveling with anytime of brace or cast, you will be taken aside and it will be manually screened. I have had 15 hand surgeries and the last time i flew I had one of my splints on and the TSA inspector took me aside and I questioned him about it. And he said that it is a TSA regulation. So don't be surprised. They run the handheld metal detector thing over it... which in my case it went wild because there's a metal bar in the splint and then they run the plastic explosive tissue over it and check it in the machine.
What ever you do . . DON'T make jokes about a bomb in your cast!
Since 9-11, I make sure to wear shoes that slip on and off, no belt etc. It makes the search quicker. There's nothing worse than being in a hurry and having to untie your shoes, take off your belt, take off your watch, check your pockets etc etc. Although I appreciate them keeping me safe, that sure is a hassle sometimes.
