The present invention provides a facet compression system, including: an articulating facet washer; one or more of a rigid, semi-rigid, and flexible cable coupled at its proximal end to the articulating facet washer; and one of a deployable and a deployed anchoring device coupled to a distal end of the cable; wherein the cable is selectively tensioned at the articulating facet washer, thereby compressing and immobilizing a facet joint of a spine of a patient. Optionally, the articulating facet washer is operable for pivoting in multiple planes relative to a structure disposed therethrough. Optionally, the articulating facet washer is operable for rotating relative to a structure disposed therethrough. Optionally, the deployable anchoring device includes an overwrapped compression cap. Optionally, the cable is selectively tensioned at the articulating facet washer via one or more of a zip tie ratchet mechanism, a crimping mechanism, and a screw mechanism.
