Abstract:
1. A method of manufacturing an intervertebral disc prosthesis for insertion into an intervertebral disc compartment which is formed between a first and a second vertebra, the method comprising the steps of: a) biometrically determining the shape of a first dome formed within an apophyseal ring of the first vertebra; b) providing a first constituent element which is provided on one side with a first joint member and has on the other side a first abutment face which abuts against the first vertebra when the intervertebral disc prosthesis is inserted into the intervertebral disc compartment, wherein the first abutment face has a shape that has no rotational symmetry and has a vertex being configured such that the first constituent element is allowed to rotate within the first dome by at least 10° when the vertex of the first abutment face contacts a vertex of the dome; and c) rotating the first constituent element using operating means after the vertex of the first abutment face contacts the vertex of the first dome, but before the first dome is deformed until its shape at least substantially complements the shape of the first abutment face, wherein the shape of the first abutment face is determined such that, after application of a force that presses the abutment face against the first dome, the first dome is deformed until its shape at least substantially complements the shape of the first abutment face.
