From what I hear, Dr. Lenke is supposed to be one of the best. I'm sure his office will get back to you; however, if you don't hear from them in a day or so, it wouldn't hurt to put in a second call. I had to do that with a NY surgeon that I wanted an appointment with. I have heard of a number of people with greater than 80 degree curves, so don't feel bad that you're alone out there.
In my case, it was about 5 or 6 months from the time that I discovered I needed surgery to the actual surgery date. The decision is a hard one to make, but once you have you will have a certain level of peace about the whole thing. Not that you still can't be nervous, but it's nice to have a plan.
