Abstract:
A removable anchoring pedicle screw includes an implant mounting screw, an anchor screw, and a nose piece. The anchor screw is configured to be rotated relative to the implant mounting screw such that the nose piece engages an expandable anchor. The expandable anchor is disposed between the implant mounting screw and the nose piece such that rotation of the anchor screw relative to the implant mounting screw causes expansion of the expandable anchor.
