Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
A sliding cervical spinal prosthesis characterized in that it comprises a part (A) formed by
a support element (1) having a plate (1b) curved to correspond very approximately with
the external profile of one of the vertebrae (C3a), the said plate (1b) forming two fixing
arms (1b1, 1b2), the said element (1) comprising a part (B) in a very approximately
horizontal plane in the form of a profiled implant (2) adapted to cooperate equally well
with the fibro-cartileginous joint surface (C2b) of the facing vertebra (C2a) as with a
complementary part (B') which another part (A') fixed integrally to the said vertebra (C2a)
provides.
Claim 2
Dependent Claim
43 words
A prosthesis according to claim 1, characterized in that the part of the support element (1)
having the implant (2) is formed by an open ring (1a), extended opposite its opening (1a1)
and in a substantially orthogonal plane by the curved plate (1b).
Claim 3
Dependent Claim
31 words
A prosthesis according to claim 1, characterized in that the implant (2) has a centring and
fixing stud (2a) adapted to be force fitted in the thickness of the ring (1a).
Claim 4
Dependent Claim
23 words
A prosthesis according to claim 1, characterized in that the implant (2) has a very
approximately circular general shape as viewed in plan,
Claim 5
Dependent Claim
37 words
A prosthesis according to claim 4, characterized in that the top face of the implant (2) has
a raised profile (2b) very approximately complementary to the hollow profile (C2b) of the
vertebra (C2a) with which it cooperates.
Claim 6
Dependent Claim
47 words
A prosthesis according to any one of claims 1 to 4, characterized in that the top face of the
implant (2) pertaining to the part (B') a hollow profile (2b') very approximately
complementary to the raised profile (2b) of the implant (2) pertaining to the part (B).
