The invention relates to a method for planning an individual interference pin eyes facettgelenk - implant (9). Furthermore, the invention also relates to a planning unit (13) for an individual interspinöses facettgelenk - implant (9) as well as a corresponding facettgelenk - implant for implantation in the interference pin eyes space.It is their object a method for planning an intermetallic pin eyes facettgelenk - implant (9), a corresponding facettgelenk - implant (9) and a planning unit (13) to describe for this purpose, with the aid of which the natural function of the vortices columns segment and a restored by means of an implant induced connection degeneration is avoided.The object is achieved by a method, in which x-ray - movement of receptacles of the affected vertebra columns section is produced, an optimum segmental height of a vortex columns segment and an optimum of segmental distance is simulated, in such a way that this a degeneration of a vortex columns segment counteracts a maximum, and the simulation results with computer tomography - receptacles are brought into agreement, in order to important production - and the function parameters for an individual interspinöses facettgelenk - implant (9) for supporting the degenerated to generate vortices columns segment.The above-mentioned object is also achieved by means of an individually scheduled facettgelenk - implant (9) and a corresponding planning unit (13).
