Abstract: The invention relates to an intervertebral disc prosthesis for the total replacement of the intervertebral disc within the lumbar and cervical spine. For a two part as well as for a three part intervertebral disc prosthesis, according to the invention, in accordance to the design of the edges of the sliding partners, there are aspects for at least one of the sliding partners, in which there is an wavelike design of the edge, as the respectively different high edge regions preferably fluently merge.

Abstract: The present invention relates to an intervertebral disc prosthesis for the total replacement of an intervertebral disc of the cervical or lumbar spine. The prosthesis provided by the invention is intended for coupled physiological motion within the disc space. The design of the disclosed prosthesis is based on an inlay positioned within the articulation area of two adjacent sliding partners and provides the advantage of comprising a ball and socket shaped articulation area, which enables limitation of rotation around the sagittal, frontal and longitudinal axis. The inlay is protected against luxation due to its position within a recess of one of the adjacent sliding partners. An additional protuberance going through the inlay is protecting against luxation of the adjacent sliding.

Abstract: Disclosed is an intervertebral disc prosthesis for the total replacement of a natural intervertebral disc within the lumbar and cervical spine, comprising of articulating sliding partners. The upper sliding partner has means for a firm assembly to an upper vertebral body and the lower sliding partner has means for a firm assembly to a lower vertebral body. At least one sliding surface is between two sliding partners. Two- and three-part functional designs are planned and both having in common, that, as a result of the shape of the articulating surface(s), the laterolateral and dorsoventral motion amplitudes differ. The resulting angles including the rotation around a fictitious vertical axis can be defined to a desired extent.
