Abstract

A vertebral facet distractor intended to be positioned between first and second articular facets in an articular facet joint to provide distraction between the first and second articular facets includes an elongated generally cylindrical contour including opposed top and bottom surfaces, an outer sidewall, an inner sidewall, and a central lumen that defines an opening in the bottom surface. The outer sidewall is provided with a surface irregularity to promote bone fusion when the vertebral facet distractor is positioned between the first and second articular facets in the articular facet joint.
