A prosthesis is a device made to replace a missing human body part. They are used by people who are missing body parts due to accidents, health problems (amputees) or being born without them. Originally, prostheses were simply pieces of wood (for example, wooden legs), but now they are made of lighter materials.
In sports[change | change source]
In Para-alpine skiing, the device needs to be made to work like an ankle because the way the ankle moves is very important in skiing. The device for skiing is only used in skiing. People use other prostheses when they are not skiing.
