Abstract
A spinal implant is provided having an elongate member with a longitudinal axis and threads extending over at least a portion of the outer surface thereof. The implant includes a stabilization feature associated with the elongate member that is selectively configurable between a delivery configuration and a deployed configuration in which the stabilization feature is oriented at an angle with respect to the longitudinal axis of the elongate member. Also, at least a portion of the implant can include a fusion-promoting bioactive material. In another aspect, the invention includes methods for providing stabilization within a facet joint by delivery of an articulating intra-facet screw.
