Abstract
A implantable interference device configured for intra-facet placement within a facet joint is provided. The device includes a shank capable of engaging opposing faces of the facet joint. The shank can further include a head extending from a proximal end of the shank wherein the head is configured to engage and/or buttress opposing faces of the joint, and also configured for preventing over-insertion of the device. Optionally, at least a portion of the shank can include or be formed of a fusion-promoting bioactive material. Further, a method for providing fixation of a facet joint by intra-facet placement of an interference device within the facet joint is provided.
