Project walk for Tay

My son went to Chicago to have growth rods put in his back for his scoliosis. The surgery was botched and now he's paralyzed from the waist down and he has a vent and a trach. I want to take him to  the children's hospital  in Boston so they can help him possibly regain his ability to walk again. I want my son to regain as much function in his legs as he can. I also want him to go back to normal as much as he can.
