Oscar Leonard Carl Pistorius (born 22 November 1986) is a South African sprint runner. Known as the 'Blade Runner' and 'the fastest man on no legs', Pistorius, who has a double amputation, is the world record holder for sport class T44 in the 100, 200 and 400 metres events and runs with the aid of Cheetah Flex-Foot carbon fibre transtibial artificial limbs by Ossur. In 2007, Pistorius took part in his first international competitions for able-bodied athletes. However, his artificial lower legs, while enabling him to compete, have generated claims that he has an unfair advantage over able-bodied runners. The same year, the International Association of Athletics Federations (IAAF) amended its competition rules to ban the use of 'any technical device that incorporates springs, wheels or any other element that provides a user with an advantage over another athlete not using such a device'. The federation claimed that the amendment was not specifically aimed at Pistorius.
