1. A kit of parts for use in inserting an interbody fusion cage between a superior vertebra and an inferior vertebra, the superior vertebra including an inferior endplate and a vertebral body, the inferior vertebra including a superior endplate and a vertebral body, the superior and inferior endplates defining a disc space therebetween, the kit comprising:
a plurality of modular inserter tips, each modular inserter tip having a distal end, a proximal end and a cage attachment surface adjacent said distal end and facing said proximal end for releasable attachment to an interbody fusion cage of respectively different sizes, each modular inserter tip having an opening extending into said proximal end for receipt of a portion of a depth stop, said opening terminating in an interior surface extending transversely within said opening and defining a depth stop contact surface, the distance between the cage attachment surface and the depth stop contact surface of each modular inserter tip being substantially the same;
a depth stop adapted to be selectively releasably attached to each modular inserter tip of said plurality of modular inserter tips, said depth stop including a tip contact surface for contacting a respective depth stop contact surface on each modular inserter tip, said depth stop including a movable stop axially movable relative to an attached modular inserter tip and being sized and configured to engage an exterior surface of one of said vertebrae when said interbody fusion cage is disposed in said disc space, said movable stop being spaced axially from a common first location on each modular inserter tip of said plurality of modular inserter tips by a first distance that is selectively axially adjustable; and
at least one elongate pull rod that is adapted to be movably received in said depth stop and releasably attached to an anchor plate supported by said interbody fusion cage having deployable anchor blades, said pull rod being operable to move proximally relative to and toward the proximal end of said modular inserter tip to deploy said anchor blades.
