Abstract
A facet joint replacement implant may have a posterior stabilization surface designed to restrict posterior motion of a vertebra with respect to an adjacent, inferior vertebra. The facet joint replacement implant replaces the natural articular surface of one of the vertebrae, and articulates with a natural articular surface or with an articular surface of a second implant on the other vertebra. The posterior stabilization surface may be on a posterior flange of a superior facet joint implant, which extends posteriorly of a corresponding inferior facet joint implant. The inferior facet joint implant has an abutment surface that abuts the posterior stabilization surface as the superior vertebra begins to move posteriorly with respect to the inferior vertebra, thereby limiting the posterior motion.
