Abstract
Areal spacers for prosthesis parts can be cemented into bones and enable a prosthesis part to be cemented in with a correction of the position of its functional surfaces without producing additional risks during the cementing. Since the spacers themselves consist of hardened bone cement, a secure, homogeneous binding with the fluid bone cement arises. At the same time, these spacers also enable a fine kit-like graduation and an exact positioning of prosthesis parts during cementing.
