From the report, it sounds like you had suffered a fracture in your spine along with spinal cord injury at that time. When did it happen? Did you lose function in your legs/ sensation in your legs immediately after the injury or did this problem happen only after the operation? In this kind of situation, it is important to go through the history in detail before any clear answer can be given. I am happy to try and help if you wanted to consult in person (if you live in Bangalore) or via video consultation.
