Abstract: The invention relates to an intervertebral disk implant having two implant plates contacting prepared vertebral body surfaces in the implanted state and an implant core which can be introduced between the implant plates. The invention further relates to a method for the manufacture of an intervertebral disk implant.

Abstract: An implant (10) for anchoring on a bone (1) has a plurality of anchoring pins (20) which extend away from a fastening side of the implant and are provided for anchoring the implant in the bone. In different areas of the fastening side of the implant, the pin arrangement and/or the geometry of the pins are chosen differently. In particular, in different areas of the fastening side of the implant, the volume of the anchoring pins (20) per unit of surface area of the fastening side of the implant is different, preferably in such a way that the geometry and/or arrangement of the pins (20) is chosen according to the proportion of bone tissue in the total tissue of the bone substance, opposite which the area of the fastening side is provided, in such a way that, in areas where there is a relatively higher proportion of bone tissue as a whole, less tissue is displaced by the anchoring pins than in areas where there is a relatively smaller proportion of bone tissue.

Abstract: A bone fixation element consisting of a hollow member having a wall, a plurality of perforations locating in the wall, a front end which is suited for insertion into the bone, a rear end, and a longitudinal axis. The stiffness of the hollow member may vary along its longitudinal axis from the rear end to the front end. Changes in the porosity and/or the thickness of the wall of the bone fixation element may result in changes in stiffness of the bone fixation element. An increase in porosity and/or decrease in thickness may result in a decrease in stiffness, and a decrease in porosity and/or increase in thickness may result in an increase in stiffness.

Abstract: The present invention concerns a fastening element for use in bone, and in particular to a device for fixating implants on or in bone. The device may have a longitudinal axis for anchoring in bone and may comprise a core and at least one wing extending from the core. The wing may have an enlarged peripheral portion adapted to contact bone. A cross-section of the device transverse to the longitudinal axis may have first and second portions, the first portion comprising the core and defining a first cross-sectional area, the second portion comprising the enlarged peripheral portion of the at least one wing and defining a second cross-sectional area, and the second cross-sectional area preferably is greater than the first cross-sectional area.
