Abstract
Abstract 1. A vertebral prosthesis comprising a plate portion (13) which is capable of being connected to two separate vertebrae, for example by scews, characterized in that, in its median zone, said plate portion (13) transversely carries in advance an artificial graft (16) made of a material suitable for promoting boney growth and having at its surface accommodation means (21) for promoting such boney growth.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
63 words
A vertebral prosthesis comprising a plate portion (13) which is capable of being connected to two separate vertebrae, for example by screws, characterised in that, in its median zone, said plate portion (13) transversely carries in advance an artificial graft (16) made of a material suitable for promoting boney growth and having at its surface accommodation means (21) for promoting such boney growth.
Claim 2
Dependent Claim
63 words
A vertebral prosthesis comprising a plate portion (13) which is capable of being connected to two separate vertebrae, for example by screws, characterised in that, in its median zone, said plate portion (13) transversely carries in advance an artificial graft (16) made of a material suitable for promoting boney growth and having at its surface accommodation means (21) for promoting such boney growth.
Claim 3
Dependent Claim
44 words
A vertebral prosthesis according to claim 1, characterised in that the artificial graft (16) is at least partially embraced over a part at least of its perimeter by two arms (17) which are fixed with respect to the plate portion (13) which carries it.
Claim 4
Dependent Claim
32 words
A vertebral prosthesis according to claim 2, characterised in that, joining together, said arms (17) jointly form a casing (18) which embraces the artificial graft (16) over the whole of its perimeter.
Claim 5
Dependent Claim
15 words
A vertebral prosthesis according to claim 3, characterised in that said casing (18) is tubular.
Claim 6
Dependent Claim
20 words
A vertebral prosthesis according to claim 4, characterised in that said casing (18) is of a section of circular contour.
Claim 7
Dependent Claim
39 words
A vertebral prosthesis according to any one of claims 2 to 5, characterised in that the artificial graft (16) and the arms (17) which embrace it extend jointly in cantilever relationship from the plate portion (13) which carries them.
Claim 8
Dependent Claim
33 words
A vertebral prosthesis according to any one of claims 2 to 6, characterised in that the arms (17) which embrace the artificial graft (16) are in one piece with the plate portion (13).
Claim 9
Dependent Claim
43 words
A vertebral prosthesis according to any one of claims 1 to 7, characterised in that, the plate portion (13) being provided at its ends with lugs (15) for receiving fixing means such as screws, the artificial graft (16) extends between said lugs (15).
Claim 10
Dependent Claim
41 words
A vertebral prosthesis according to any one of claims 1 to 8, characterised in that the accommodation means (21) of the artificial graft (16) extend in the form of tubes from one of the transverse surfaces (20) thereof to the other.
Claim 11
Dependent Claim
31 words
A vertebral prosthesis according to any one of claims 1 to 9, characterised in that the plate portion (13) is of metal and the artificial graft (16) is of sintered alumina.
