Uday Hussein
In December 1996, somebody tried to assassinate Uday.  Uday was driving at the time, and he was hit by many bullets.  He was permanently injured. At first, doctors thought he was paralyzed. He was evacuated to Ibn Sina Hospital. He had many surgeries, but a bullet was so close to his spinal cord that his doctors could not remove it. Eventually, he was able to walk, but not without a limp. Because of Uday's disabilities, Saddam gave Qusay more responsibility and authority, and named him as his heir apparent in 2000.
