Abstract

A spinal stabilizing system includes a collar having a tubular sidewall with an interior surface and an exterior surface, the interior surface at least partially bounding a longitudinal passage extending therethrough. A shoulder radially inwardly projects from a second end of the sidewall so as to at last partially encircle the longitudinal passage. A pair of spaced apart channels transversely extend through the sidewall at the first end thereof. The system further includes a screw having a threaded portion and an enlarged head mounted on the end thereof, the head of the screw resting against the shoulder of the collar so that the head can pivot on the shoulder, a locking slot being formed on the head of the screw. A pin is secured to the collar and projects into the locking slot on the head of the screw such rotation of the collar facilitates rotation of the screw.
