Abstract: A translaminar screw is formed from a polymer material (such as PEEK, PLLA, PCL, carbon fiber PEEK, and the like) so that the screw does not come loose, even after an extended period of mobilization. Spinal implants, instrumentation, and methods relating to stabilization and/or fusion of a facet joint via trans-facet and intra-facet delivery of the implants are disclosed herein. The implant or screw functions as a sort of flexible mechanical staple and/or key that prevents sliding motion between the diarthroidal surfaces of the facet joint. The spinal implant includes an elongated member extending from a distal tip to a proximal end having a head formed thereon. The elongated member can further include a threaded portion. The implant member can be, for example, a polymer translaminar screw that is formed from one of a PEEK, PLLA, PCL, carbon fiber PEEK, or similar polymer or other relatively flexible material.
