One really important caveat here-- nature abhors a vacuum, and spinal cord injuries are no exception. A chronic injury to the spinal column will result in scar tissue coming in over the wound, which is a totally separate issue from the initial injury. If your spinal cord injury is over a month old, you have a completely separate problem, ie, how to clear out the scar tissue so that nerve regeneration is even possible.
