Martial arts training afters scoliosis surgery?

I had scoliosis surgery 12 years ago and have harrington rods on my spine. However, i have done may activities since the surgery, including taekwondo for two years, without issues and have now considered hapkido. I was just wondering if it is safe for people who have had this surgery considering the throwing and falling of this martial art. I have done a little of it in my taekwondo class and didn't have issues, but we never got to the full extent of falling and throwing.
