<p>The invention relates to a prosthesis for the partial replacement of a vertebralbody, comprising an upper connection plate (5) for connecting to an upper vertebralbody (1), a lower connection plate (6) for connecting to a lower vertebral body(2) and a bridging part (7), which interconnects the upper and lower connectionplates (5, 6) with the inclusion of at least one articulation for bridging at leastone vertebral body (3) that lies between the upper and lower vertebral bodies(1, 2) and is to be partially replaced. The bridging part (7) is accommodated ina cavity of the vertebral body (3). The bridging part comprises lateral anchorprojections (9) to secure it in the cavity, said projections penetrating theosseous material that lies on both sides of the bridging part (7). The cross-sectionof said part narrows towards the rear, preferably having a trapezoidal shape.</p> |
