A 38-year-old Bulgarian man who was paralyzed from the waist down can walk again after groundbreaking surgery, and is believed to be the first person in the world to recover from complete severing of the spinal nerves. Polish surgeons transplanted nerve-supporting cells from Darek Fidyka's nose to his spinal cord in order to help the ends of severed spinal nerve fibers to grow and rejoin, something previously thought to be impossible, reported The Guardian newspaper in the U.K. The successful surgery on Fidyka, who was paralyzed four years ago, offers hope to the millions of spinal cord injury patients around the world.
