An intervertebral spinal implant includes a shaped body with a first bearing side, a second bearing side located opposite to the first bearing side, a front part, a rear part, a concave side and a convex side. The concave side and the convex side are both connected to the bearing sides as well as to the front part and the rear part. The first bearing side and the second bearing side are each provided with at least two projections for penetration within a vertebral body's wall. The projections are formed by elongated sliding-guiding runners which extend in a diverging manner from the concave side of the body towards the convex side of the body. The sliding-guiding runners extend in a curved manner so that they also extend from the concave side of the body towards the rear part of the body in addition to extending towards the convex side of the body. The sliding-guiding runners are provided with a smooth surface facing the convex side of the body and with a rough surface facing the concave side of the body.

Intervertebral spinal implant

A prosthesis of an anterior spinal column, comprising a perforated sleeve body () with at least one anchoring element, teeth and overgrowth holes and a positioner () situated within the body (). The body () has in its wall at least one manipulative hole () and at least one positioning hole (), whose longitudinal axes are parallel with each other. The positioner () comprises at least one situating element () cooperating with at least one positioning hole () of the body () and at least one hole () formed therethrough, which may be situated radially inward relative to the manipulative hole (). At least one end face () of the body () or/and body's wall are provided with at least one pair of opposite guidelines (). For introducing the prosthesis into the intervertebral space, a guiding instrument is used in the form of a rod with a shaped working element () at one end. The prosthesis may be implanted with the use of the prosthesis guiding instrument.
