  • Patent number: 6106557
    Abstract: A reconstruction system for vertebra, with at least one annular middle body and two annular end bodies. The end surfaces of the middle body and of the end bodies are formed such that the bodies may be stacked over one another and one end surface of the end bodies comprises a receiving section. The system includes two approximately right-angled vertebra body plates having a pair of limbs. One limb is formed such that in a direction perpendicular to the axis of an end body, it is insertable into the receiving section in a manner such that the one limb is prevented from moving away from the end body in the direction of the axis. The other limb comprises at least one bore for a bone screw and at least one threaded bore. A connection plate is provided, which at the ends comprises openings for connection to the other limb of each vertebra body plate via a screw.
