Definitions

  • the invention relates to an implant for fixing adjacent spinal bones of the spine, which are partially removed on the opposite surfaces to form a receiving space for the implant to be driven in with a tool.
  • an open-cell implant bone tissue with subsequent bone cell formation can ingest in a known manner and thereby form a unit with the bones.
  • Such an open-cell implant must be pushed out from the abdominal cavity after the viscera has been pushed sideways Hammer or striking tool are driven into the created receiving space of the adjacent vertebral bones, and this is only possible if the attack surface of the implant for the striking tool is solid, because otherwise the cell wall parts of the implant could splinter and then cause damage lead for the patient.
  • the angle of inclination is small and is between about 4 to 8 °.
  • the wall thickness of the tubular body is approximately 3 to 6 mm, and the proximal end of the metallic implant which faces the attack of the striking tool or which has a larger diameter, or else both ends, are to be designed with solid walls. This can be achieved, for example, by one or both ends of the open-cell, metallic implant consisting of a full-walled metallic ring or exist which is or are connected to the open-cell implant body by welding.
  • FIG. 1 shows a cylindrical or frustoconical implant body with an interrupted longitudinal section and an end view
  • FIG. 2 shows a tubular implant body in
  • Figure 5 is a partial side view of the spine with a partial section through two adjacent vertebrae fixed by the implant. 20th
  • the implant 1 consists of an open-celled, metallic body in the form of a cylinder according to FIG. 1 or a tube according to FIG. 2, the body being advantageously conical with an angle of inclination between 4 25 to 8 ° and with a wall thickness of the tubular Im ⁇ plantates between 3 to 6 mm.
  • the implant 1 to be driven with a hammer or a striking tool into a receiving space produced by prior removal on the facing surfaces of two adjacent vertebral bones 2 and 3 has a full-walled design at a proximal end 4 to which the striking tool engages. It is advantageous that the other-
  • the full-walled ends 4 and 5 of the implant 1 can consist of metallic rings which are welded to the open-cell, metallic implant body 1.
