Abstract:
1. An implant for an intervertebral space comprising: a shaped body comprising: a top contact surface to be placed on an end plate of the vertebra adjoining the implant from above, a bottom contact surface to be placed on an end plate of the vertebra adjoining the implant from below, wherein the top and bottom contact surfaces are convex; two lateral side surfaces having a length greater than their width, a front and a rear surface as well as a central axis that intersects the two contact surfaces, a longitudinal axis that intersects the front and rear surfaces, and a transverse axis that intersects the lateral side surfaces; an opening extending along an axis that is parallel to the central axis; and a central plane defined by the longitudinal axis and the transverse axis and situated between the contact surfaces and at right angles to the central axis of the body, wherein the contact surfaces have a plurality of teeth with central axes, wherein the central axes of the plurality of teeth are inclined relative to the central plane in such a manner that rotation of the body 90 degrees about the longitudinal axis is facilitated in one direction and impeded in the other direction; and wherein the maximum distance between the two lateral side surfaces is smaller than the maximum distance between the two contact surfaces.
