Spinal/skull fixation device
First Claim
1. A device for fixation of a skull to bones of an adjacent spine comprising biocompatible rod-like material formed in the slope of a loop of substantially circular form terminating in and connecting a pair of generally parallel legs, with the loop and the legs at their junction lying in planes that are generally perpendicular to each other, and the legs being provided adjacent said junction with opposed kinks extending away from each other, whereby, when the loop has been secured to the base of the skull by means of wires passing through holes in the skull and the legs have been secured to bones of an adjacent spine by sublaminae wires, wires engaged round the legs at both sides of the kinks effect fixation of the skull in relation to the adjacent bones of the spine.

Abstract
A device for fixation of the skull (15) to adjacent bones (18A . . . 18E) of the spine (19) comprises a loop (11) of substantially circular form connecting a pair of legs (12) generally perpendicular to the loop, outward kinks (14) being provided adjacent the junction of the loop and legs, whereby, with the loop secured to the skull by wires (16) and the legs secured to the spine by sublaminae wires (20), wires (20'"'"', 20") at both sides of the kinks (14) effect fixation of the skull in relation to the adjacent bones of the spine.
