If you look at videos from last year, Alan was shorter than me but now he's taller than me. 

South African legend Oscar Pistorius lost his first competitive 200 metre sprint this morning at the London Paralympic Games and then lit another controversy for officials to handle when the celebrated athlete questioned the fairness of the prosthetics worn by his Brazilian conqueror.

Those in attendance for Pistorius's first final in the stadium since his participation in the Olympic Games last month were left stunned as Pistorius, who had a large lead as he entered the straight, was run down by Alan Oliveira.

Oliveira won the T44 race in 21.45 seconds, with Pistorius 21.52 and American Blake Leeper finishing in 22.46.

However, it was not only the crowd that was unhappy that Pistorius was not able to complete his fairytale return to the Paralympic arena following his foray into the Olympics, where he ran a 400 semi-final and was part of the South African 4x400 relay team that made the final .

The International Paralympic Committee use a formula to determine the length of the blades used by competitors and the prosthetics, or carbon fibre blades were measured on race day, but Pistorius claimed that Oliveira's were too long.

"We're not racing a fair race here," Pistorius said.

"I don't think there's any difference in the stuff that he uses and we use, it's all the same but there are restrictions on their heights and the guys have made their heights a lot higher in the last couple of months so I think that definitely needs looking at," Pistorius said.

"If you look at videos from last year, Alan was shorter than me but now he's taller than me. I don't take away from their performances. I think they're great athletes, but it's clear that these guys have very long strides.

"Alan's a great athlete he's always been up there among the top. I  think he's a terrific guy and a terrific athlete but he's never run a 21 second race and I don't think he's a 21 second athlete."

"I've never lost a 200 race in my career. I've never seen a guy come back from eight metres on the 100 metre mark to overtake me on the finish line. I've never seen that in my life."

Pistorius said he raised concerns to the IPC after the US trials, "but nothing's been done about it".

"I believe in the fairness of sport I believe in running on the right length. We've got a formula that is pretty much the same for every person ... and I stuck with that years."

However, the IPC which has dithered and backflipped for days after a bungle in awarding the medals for the F35/36 discus competition, was quick to act on Pistorius' comments. He was taken back to the media to stand with an IPC spokesperson who read a prepared statement.

"Following tonight's race Oscar has shared his concerns with the International Paralympic Committee and we have had a meeting discuss those concerns," the director for communications Craig Spence said.

" We have agreed that we will meet again with our Science and Medial Director for Oscar to share his concerns without the emotions of tonight's race and the timing of that meeting will be established in due course.
