HELICAL LOCK SPACER, INSTRUMENTS AND METHODS
First Claim
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.

Abstract
Disclosed are bone spacing implants for bone fusion with an open helix locking system and insertion instrumentation for implanting a spacer and fixating with a helix lock without removal of instrumentation between steps. Implanting methods comprise the steps of: positioning a coil driver over an elongate shaft portion of a bone spacer inserter; loading a helical lock implant on a distal end of an elongate shaft portion wherein an elongate shaft portion occupies a central core space of the helical lock; positioning and fixing a selected bone spacer implant to the bone spacer inserter instrument; advancing the bone spacer and helical lock instrumentation assembly into an intervertebral space; advancing through rotation a coil driver transmitting torsional forces against a butt surface of a helix lock until the helix lock is fully threaded into adjacent bone and the bone spacer.
