Talk to Neuro Physician on Fracture In Vertebral Column

My cousin 25 years old was playing hide and seek with friends. His friends fulled up in the air and left him to fall to the concrete ground. He fell and struck the ground. Then he was unable to stand up and get immobilised. We took him to the hospital and the Dr. recommended the x-rays, CT scan, and MRI. After performing all the tests, the attending surgeon advised him to go through surgery, but there is an 80% chance of cutting the nerve which would lead to being paralysed. Now he is not feeling well and having backache while roaming with a bent back. Need expert advises
