Method and apparatus for directional guidance in the performance of a partial vertebrectomy within a cervical spine

A physical guidance device for use in guidance of a bone removal tool in performance of an anterior cervical surgical procedure that includes placing an implant into a void created between two vertebral endplates of a single vertebra in a cervical spine, the implant having been given clearance from the Food and Drug Administration (FDA), wherein the performance of the anterior cervical surgical procedure results in leaving adjacent intervertebral discs functionally intact.

A physical guidance device for use in guidance of a bone removal tool for performing a multi-aperture surgical procedure involving a vertebral body of a cervical spine during performance of an anterior cervical spinal surgery, the multi-aperture surgical procedure including creating a first void in the vertebral body, the first void having an entrance and a terminus region, and creating a second void in the vertebral body of the cervical spine where the first void was created, wherein at the conclusion of the surgical procedure the endplates of the single cervical vertebra remain functionally intact.

A physical guidance device for use in an anterior cervical spinal surgical procedure that does not include a fusion to an adjacent vertebra, the physical guidance device being used for guiding removal of bone from a selected starting point to a selected termination point during performance of surgical procedure involving a cervical vertebral body, the procedure including placement of an implant into a void created between vertebral endplates of a single vertebra of the cervical spine, the implant having been given clearance from the Food and Drug Administration (FDA).
