1. ) A method of implanting a bone spacer having a helical lock in an intervertebral space comprising the steps of:

  • obtaining a bone spacer inserter instrument comprising an elongate shaft portion and a central locking rod portion;

    positioning a coil driver over said elongate shaft portion of said bone spacer inserter;

    loading a helical lock implant on a distal end of said elongate shaft portion wherein said elongate shaft portion occupies a central core space of said helical lock and wherein a cutting tip of said helical lock is orientated distally on said bone spacer inserter;

    positioning a bone spacer implant against an engagement face disposed on a distal end of said elongate shaft portion;

    advancing said locking rod portion into a spacer lock of said bone spacer thereby fixing said bone spacer implant to said bone spacer inserter instrument;

    advancing the bone spacer and helical lock instrumentation assembly through an incision and into a predetermined position in an intervertebral space;

    advancing through rotation said coil driver about its central axis thereby driving a tooth face on said coil driver to transmit torsional forces against a butt surface of a helix lock;

    and continuing torsional forces on said coil driver until said helix lock is fully threaded into adjacent vertebral bone and said bone spacer.
