Hi Carol,
Sure. I had a patient a few years back that ended up in the ED with symptoms of a heart attack that were simply symptoms of extreme anxiety from his cast. He was a big, strong, strapping guy who worked at the local drag strip. Needless to say, he was no sissy but just got the same cast-trophobia as you describe.
First, make sure your surgeon knows your concerns. S/he is going to stress the hard cast with the nature of the surgery. But I'm sure that your doc could do two things. First would be to use a splint of some sort or a removable cast. But to do so, I'm sure s/he is going to require you to raise your right hand and swear on a stack of bibles to be good.
Second would be to use an anti-anxiety agent like Xanax during the course of your cast.
