Czyz with his "space" improved prosthesis

Wojtek Czyz with his improved long-jump prosthesis. The prosthesis consists of four pieces. The first is a shaft used to attach the prosthesis to the stump of the leg, the second is the artificial knee, the third is the knee joint element, an L-shaped bracket connecting the artificial knee to the fourth element, a carbon fibre spring that substitutes for the lower part of the leg and the foot.
