Abstract

The intervertebral implant is in the form of a three-dimensional structure (10) comprising (a) a top side (1) and an underside (2) which are designed to rest against the end plates of two adjacent vertebras, (b) a left side face (3) and a right side face (4), (c) a front face (5) and a rear face (6), (d) a horizontal center plane situated between the top side (1) and the underside (2), (e) a vertical center plane (8) situated between the left side face (3) and the right side face (8) and (f) a plurality of boreholes (9) passing through the implant structure (10) that are designed to receive longitudinal affixation elements (20), the axes (19) of said elements intersecting the horizontal center plane (7). At least one of the boreholes (9) is designed in a manner that the affixation element (10) received in it can be rigidly connected to the intervertebral implant. Said connection is implemented using a thread or by matching conical surfaces.
