Lateral mass fixation system

Abstract

A device for accessing and guiding at least one fixation device to a spine may include a distal portion configured to fit in a facet of the spine and a proximal portion extending from the distal portion. The proximal portion may be detachable from the distal portion and may be hollow or solid. A system for accessing and guiding at least one fixation device to a spine may include a distal portion configured to fit in a facet of the spine, a proximal portion extending from the distal portion, and a slidable guide device for sliding over the facet guide device to guide at least one instrument to the spine.
