Oscar Leonard Carl Pistorius is a South African former professional sprinter and convicted murderer. Both of his feet were amputated when he was 11 months old as a result of a congenital defect; he was born missing the outside of both feet and both fibulae. Pistorius ran in both nondisabled sprint events and in sprint events for below-knee amputees. He was the 10th athlete to compete at both the Paralympic Games and Olympic Games.

The Paralympic Games or Paralympics, also known as the Games of the Paralympiad, is a periodic series of international multisport events involving athletes with a range of disabilities. There are Winter and Summer Paralympic Games, which since the 1988 Summer Olympics in Seoul, South Korea, are held almost immediately following the respective Olympic Games. All Paralympic Games are governed by the International Paralympic Committee (IPC).
