Abstract

A prosthesis for partial replacement of a vertebral body includes upper and lower contact plates that contact upper and lower vertebral bodies and a bridging element to be inserted into a bone cavity that bridges an intermediate vertebral body to be replaced that lies between the upper and lower vertebral bodies. The bridging element has anchoring projections which can be moved between a retracted implantation position and a protruding anchoring position.
