Anchor removal instruments and methods for using the instruments are provided. In some embodiments, an intervertebral implant anchor extractor tool comprises a support, a support retainer configured to hold the support fixed with respect to the implant, an extractor having an anchor retainer, and an extractor guide. An embodiment of a method of using this implant anchor extractor tool comprises the steps of obtaining access to an anchor, grasping the anchor, and applying a withdrawal force on the anchor while applying a countervailing force against the implant or a vertebral structure.
1. A tool for removing an anchor from an intervertebral implant comprising: an elongated support comprising a vertebral body bumper at a first end of the support and a stabilization handle disposed perpendicular to the elongated support proximal to a second end of the elongated support;a coupler con
1. A tool for removing an anchor from an intervertebral implant comprising: an elongated support comprising a vertebral body bumper at a first end of the support and a stabilization handle disposed perpendicular to the elongated support proximal to a second end of the elongated support;a coupler configured to fix the support to the implant;an elongated extractor comprising an anchor attachment at one end of the extractor and an extraction actuator, the anchor attachment adapted to couple to an anchor disposed within a channel of the intervertebral implant;an extractor guide disposed along the support proximal to the first end of the support; andan extractor support disposed along the support proximal to the second end of the support, wherein the elongated extractor is supported by the extractor support and guided, by the extractor guide, into engagement with the anchor to facilitate coupling the anchor attachment with the anchor for removal of the anchor from the channel of the intervertebral implant. 2. The tool of claim 1 in which the coupler comprises a rod with screw threads on one end and a drive adapter on another end. 3. The tool of claim 2 in which the elongated support further comprises a tube extending between the first end of the support and the second end of the support, the tube configured to hold the coupler. 4. The tool of claim 1 further comprising a drill. 5. The tool of claim 4 in which the elongated support further comprises a head and a removable drilling guide receivable in the head. 6. The tool of claim 1 in which the anchor attachment comprises a hook and a closure configured to grasp an anchor. 7. An instrument for removing an anchor from an intervertebral implant comprising: a support comprising a vertebral body bumper and a stabilization handle;a coupler configured to fix the support to the implant;an extractor comprising an anchor attachment and an extraction actuator, wherein the anchor attachment comprises a hook and a sliding rod closure mechanism; andan extractor guide disposed along the support. 8. The instrument of claim 7 in which the coupler comprises a screw. 9. The instrument of claim 7 in which extraction actuator comprises a handle. 10. The instrument of claim 7 in which the extractor further comprises a rod extending between the anchor attachment and the extraction actuator. 11. An intervertebral implant anchor extractor tool comprising: a support comprising a stabilization handle;a support retainer configured to hold the support fixed with respect to an implant;an extractor having an anchor retainer, the anchor retainer including a clamp comprising a hook and a tip of a slidable rod; andan extractor guide. 12. The anchor extractor tool of claim 11 in which the extractor comprises guide surfaces configured to mate with complementary surfaces of the extractor guide. 13. The anchor extractor tool of claim 12 in which the guide surfaces comprise a planar surface configured to mate with a complementary planar surface of the extractor guide. 14. The anchor extractor tool of claim 11 in which sliding of the slidable rod is controlled by a rotating knob encircling the slidable rod. 15. A vertebral implant system comprising the anchor extractor tool of claim 11, an implant anchor, an implant having a pathway configured to receive the anchor from a side of the implant and guide the anchor into a vertebral endplate, and a tool configured for insertion of the anchor to the implant and a vertebral endplate. 16. The vertebral implant system of claim 15 in which the anchor comprises a body having at least one curved plate elongated along a longitudinal axis extending between a penetration end of the anchor and a driving end of the anchor, and a longitudinal rib extending along at least part of a face of the plate.
