(1) A man who was paralyzed in a car crash four years ago has regained some use of his hands. Surgeons at Washington University School of Medicine in the U.S. took healthy nerves from other parts of the man and used them to rewire the nerves in his arm. (2) The 71-year-old broke his neck in the accident and was left unable to walk. Though he could still move his arms, he had lost the ability to grasp or hold things in either hand. The university doctors said the pioneering operation may prove to be a breakthrough for some patients with spinal cord injuries. (3) The man received extensive therapy after the operation. He was able to move the thumb and fingers of his left hand eight months after surgery. After ten more months, the patient could move the fingers of his right hand and begin to feed himself and even write to some extent considering the severity of his injury and the fact that 22months had passed between his accident and the surgery, these results are remarkable.
