Abstract

The hook (32) comprises a body (33) and a laminar portion (37) which is suitably profiled and adapted to penetrate a foramen opening at the base of the occiput against which it bears. The body is arranged to receive an osteosynthesis rod or plate and has a plane of symmetry (P). The laminar portion (37) has a curvature adapted to the thickness of the occipito-cervical shell and is inclined relative to one side or the other of the plane of symmetry (P) so as to be adaptable to the anatomy of the edge of the occiput in the region of the foramen. This inclination may be for example substantially 45°. This asymmetry of the laminar portion (37) relative to the body (33) of the hook (32) enables the surgeon to avoid having to previously remove a piece of the edge of the occiput of the patient and consequently damage the occiput.

Claims

AMENDED CLAIMS [received by the International Bureau on 5 December 1995 (05.12.95); original claims 1 and 2 amended; remaining claims unchanged (1 page)]
1. Hook for an occipito-cervical'rod or plate of an occipito-cervical osteosynthesis instrumentation, said hock comprising a body suitably profiled and adapted to penetrate a foramen opening at the base of the occiput against which it bears, said body being adapted to receive an osteosynthesis rod or plate and having a median plane of symmetry said strip being inclined relative to either side of said plene of symmetry with respect to which two branches of its body are symmetrical so as to adapt itself to the anatomy of the edge of the occiput in the region of the foramen, said strip being itself symmetrical on each side of a median plane angularly offset from said plane of symmetry by a determined angle.
2. Hook according to claim 1, wherein said angle relative to said plane of symmetry is about 45 degrees.
3. Occipito-cervical osteosynthesis instrumentation comprising two separate similar parts, namely a right part and a left part, each part being constituted by a cervical rod having asperities and an elongate occipital plate which is in one piece with said rod and extends said rod toward said occiput in the position of use, and adjustable means for anchoring said rod to the vertebrae C1-C3 and for anchoring said plate to said occiput, each of said parts being pre-angulated and so profiled as to be adapted to the anatomy of the occipito-cervical connection, said adjustable means for anchoring said plate to said occiput comprising hooks adapted to penetrate the foramen openings at the base of said occiput against which they bear, each
