Abstract
Abstract The intervertebral prosthesis, which can be implanted from the ventral direction, consists of a disc-shaped prosthesis body (1) on whose ventral edge (3) there are tabs (4) with through openings (5) for bone screws. <??>The new prosthesis guarantees, as an intervertebral disc replacement, a stable stiffening (arthrodesis) of two vertebrae (6) relative to one another, both immediately after implantation by means of screwing to the vertebrae (6), and in the long term by means of the incorporation and adherence of bone tissue. <IMAGE>

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
53 words
A metal intervertebral prosthesis for an arthrodesis, the prosthesis consisting of a discoid prosthesis body (1), tabs (4) which are formed with passages (5) for bone screws being devised on the ventral edge (3) of the body (1), characterised in that the thickness of the prosthesis body (1) narrows conically ventrally to dorsally.
Claim 2
Dependent Claim
15 words
A prosthesis according to claim 1, characterised in that the prosthesis body (1) is reniform.
Claim 3
Dependent Claim
30 words
A prosthesis according to claim 1 or 2, characterised in that the disc surfaces of the prosthesis body (1) have a structure (2) promoting the invasion and/or ongrowth of tissue.
Claim 4
Dependent Claim
20 words
A prosthesis according to claim 3, characterised in that the structure (2) comprises at least one single-layer metal wire mesh.
