Dancing hip hop ---> back problems?

Hello,

I've had a scoliosis surgery in July 2011 (so, 1 1/2 years ago). During this surgery, two steel rods and 16 screws were implanted to my spine.

I went to hospital half a year ago from now (in August 2013). The doctors told me that everything's fine. A few weeks ago, my orthopaedist x-rayed me one more time, and he told me the same.

Before the surgery, the doctors had told me I was going to be able to do everything one year after it if everything's healed well. Then, one year after it, when I asked whether I may dance hip hop, they said no and also forbade me some other things, although everything had healed.

Now, I want to try dancing hip hop yet. My friend also does, and she told me in the beginning you would only move your arms and legs. But would it make sense to start dancing if I can't bend over? I know I will never be able to do some special steps. It's stupid if I begin, like it and then have to stop. I've already tried dancing hip hop on a class trip and I liked it. During this class trip, our teacher taught us some steps. And is dancing hip hop really bad for one's back?
