  • Publication number: 20040015168
    Abstract: A surgical method and apparatus for implanting a spinal fusion implant includes a rigid centering guide having a distal end sized to be inserted into the disc space with the guide extending along a longitudinal axis from a distal end to a proximal end. The guide includes a first external guide surface which extends at least partially between the distal end and the proximal end. The external guide surface is shaped complimentary to an external guided surface of a drill guide. The external guide surface and the guided surface are nested such that the guided surface slides against the external guide surface along a path of travel parallel to the longitudinal axis.
