Abstract
Instruments and methods for inserting a spinal fixation rod include various components for inserting a rod with visual guidance. One kit includes a plurality of hollow elongated extension tubes and rod templates. The tube connectors connect the extension tubes in series. Another kit includes a rod guidance instrument having a sleeve. A guide member is attachable to the midsection of the sleeve, and a spinal fixation rod is attachable to the distal end of the sleeve. A method for inserting a spinal fixation rod into a plurality of rod receiving implants includes the steps of contouring a fixation rod to conform to a predetermined shape, contouring a guide member to match the shape of the contoured rod, and guiding the fixation rod into a rod receiving implant by maneuvering the guide member through a guide slot representing the location of the rod receiving implant.
