Abstract: Implementations described and claimed herein provide a spinal facet cage implant for implantation in a spinal facet joint. In one implementation, the implant includes a distal leading end, a proximal trailing end, a first face, and a second face. The distal leading end has a distal surface generally opposite a proximal surface of the proximal trailing end. The first face has a first surface that is generally parallel with a second surface of the second face. The first and second faces extend between the distal leading end and the proximal trailing end. The first and second surfaces having one or more textured features adapted to provide friction with the spinal facet joint. One or more windows are defined in the first and/or second surfaces, and one or more side windows are defined in the first and/or second side surfaces.

Abstract: A method for implanting a bone screw in a vertebra may first involve inserting the bone screw and a bone screw delivery mechanism through a proximal end of a guide tube along a first trajectory. A proximal end of the bone screw is attached to a distal end of the bone screw delivery mechanism, and a distal end of the guide tube is positioned adjacent the vertebra. The method may next involve advancing the bone screw and the bone screw delivery mechanism through a bend in the guide tube to cause the bone screw to exit the distal end of the guide tube along a second trajectory and contact the vertebra. The method may further involve rotating the delivery mechanism to cause the bone screw to screw into the vertebra and detaching the bone screw delivery mechanism from the bone screw.
