Abstract

A vertebral column replacement body or spacer has first and second anchoring sides each facing in the mounted or implanted state of the body an adjacent vertebra, wherein each anchoring side has a tooting for ensuring that displacement in the ventral or dorsal directions is safely prevented. The vertebral column replacement body has two body elements which are slidingly guided relative to each other and transversely of the anchoring sides, wherein, after a desired relative position has been reached, a first body element can be braced against the second body element by radially widening the first body element.
