Abstract

The invention relates to a spinal implant composed of a plurality of parallel plates. The deliberate introduction of contours in the plates allows for the creation of biomechanically advantageous functions and adjustment options. The elasticity of the anchoring elements enables the disclosed implant to be adjusted to the osseous endplates, resulting in uniform force distribution and thus prevention of the risk of compaction or endplate compression fracture. The plate structure allows for the use of production methods in which hook-like undercut contours can be created, thus enabling the implant to be superbly anchored in the bone without causing damage thereto. Furthermore, the plates can be interconnected by an actuator in such a way that the height and/or the angular position can be adjusted. The vertical adjustment can vary along the length of the implant such that the segment can also be angularly adjusted.
