I have a back surgery that was done on 2008 due to an scoliosis problem I have rods. Is it ok if I do a sky jump with an instructor???

Better ask the surgn. The specifics of your general health and or how involved your case is is beyond the scope of an internet answer. You should ask your PCP and or the doc who handled the scoliosis surgery if this would be something you are free to do. Since there is a chance of an abrupt stop (crashing into ground at high speed), this may be something you and your rods should not do.
