Emmett has never been able to walk as well as other children. He has cerebral palsy. When doctors predicted he might soon need a wheelchair, the future looked grim. An American surgeon learned of his plight and offered to help. Within days, 12-year-old Emmett had flown to the United States where they used a special computerised system to pinpoint precisely what had gone wrong. The doctors decided massive surgery might help to put things right. But there were no guarantees. So it was back to the drawing board for Emmett and he was scared. Yet it was his big chance to live like other people - on his own two feet.
