Abstract
Abstract The invention presents a prosthetic intervertebral disc which is formed such that its outer dimensions match a natural intervertebral disc and connects two adjacent vertebrae with its upper and lower reception surface (2, 3). The body of the intervertebral disc (1) is made of one part, comprises a solid, elastically deformable material and has parallel, partially overlapping slits (5) transversely to the connecting axis (4). At the same time, the adjacent slits (5) form parts of leaf springs (7) in a region of overlap (6) for transmission of forces from a reception surface (2) to the other reception surface (3). <IMAGE>
