摘要:
An implant and method for spinal facet joint stabilization uses a wedge and plate adapted to accept prongs of a surgical instrument for installing the implant into a posterior spinal facet joint. The wedge has an anterior end with a threaded bore. A notch in each lateral side of the plate aligns with a groove in each lateral side of the wedge. Each notch and groove pair receives a prong of the surgical instrument to hold the wedge and plate during implantation. A superior tube of the surgical instrument supports a superior rod having an end configured for installing a bone screw attaching the plate to the superior vertebra of the spinal facet joint. An inferior tube of the surgical instrument supports an inferior rod having an end configured to attach to the threaded bore of the wedge along with the plate during introduction of the implant into the spinal facet joint, and installing the set screw to attach the plate to the wedge.
