    摘要： The invention relates to a surgical instrument for determining the size and/or height of an intervertebral implant that can be inserted into an intervertebral gap between two neighbouring vertebral bodies of a vertebral column, said intervertebral implant having a first contact element that rests on an articular surface of a vertebral body and a second contact element that is mounted directly or indirectly on the first contact element and that is designed to rest on an articular surface of the other vertebral body. The instrument comprises a retaining part that defines a longitudinal direction and at least one sample implant containing a first and a second sample-implant contact element, each of which having at least one contact surface designed to rest on one of the articular surfaces. One distal end of the retaining part is provided with at least one contact-element retaining element for detachable connection to the sample implant(s). The first and/or the second sample-implant contact element can be detachably connected to the contact-element retaining element(s) in relation to the longitudinal direction in at least two defined, different angular positions relative to the contact-element retaining element.

    摘要： The invention relates to an intervertebral implant (1) comprising two carrier plates (4, 6) for arranging on adjacent vertebral bodies, with a convex, bulged, articulated surface (15) on one carrier plate, and a concave, bulged, articulated surface (14) on the other carrier plate, said articulated surfaces being flat against each other and thus supporting the carrier plates in a pivotable manner, and the highest or lowest point of the articulated surfaces being positioned between the rear edge (16) and the centre of the carrier plates. The aim of the invention is to achieve an introduction of force which is as homogeneous as possible from the carrier plates into the adjacent vertebral bodies. To this end, the convex articulated surface in the central region of the carrier plate extends on both sides of the central line of the carrier plate between the front edge (17) and the rear edge (16), approximately at the same distance, and projects further from the carrier plate on the end thereof facing the rear edge than on the end thereof facing the front edge.

    摘要： The invention relates to a kit for an intervertebral implant (1), which comprises an upper and a lower end plate (4, 5) which are fitted to adjacent vertebral bodies (2,3) and bearing elements which are arranged between the end plates and which can be used to pivot opposite supports of the end plates. According the invention, the outer sides of the end plates, which are oriented towards the vertebral body, comprise anchoring projections (10, 11). The kit comprises end plates of a first type which comprise at least one anchoring projection which is embodied as a fin or a rib (9) and which extends in a parallel manner in the direction of insertion of the intervertebral implant, and end plates of the second type, whereby the anchoring projections thereof are different from fins or ribs, which extend in a parallel manner in the direction of insertion in such a manner that the anchoring of the end plates can be adapted to the anatomical features. Also, for each intervertebral implant, the kit comprises end plates of the first type and also of the second type. The invention also relates to an intervertebral implant which is constructed in said manner.
