Skull to spine fixation device
First Claim
1. A spinal fixation device for fixation of a skull to adjacent bones of the spine consisting of a rod of biocompatible material formed into a loop having two straight spaced coplanar portions intermediate two bights which extend in planes that are not parallel to each other and are not perpendicular to the plane of the straight intermediate portions, wherein one of said bights is substantially circular in a curved plane starting generally perpendicular to the plane of the straight intermediate portions and curving away therefrom, and having the other bight generally V-shaped with its apex extending towards the substantially circular bight, whereby the apex of that V-shaped bight can be accommodated between the adjacent pair of spinous processes closest to the skull against which the substantially circular bight lies.

Abstract
A device (10B) for fixation of a skull (20) to adjacent bones (21) of the spine has one generally circular bight (13B) in a curved plane starting generally perpendicular to the plane of two straight spaced complanar portions (11B) and curving away therefrom, and another bight (12B) of generally V-shape with its apex (14B) extending towards the substantially circular bight (13B) so that the apex (14B) of the V-shaped bight can be accommodated between the adjacent spinous processes (16D, 16E) closest to the skull (20) against which the generally circular bight (13B) lies.
