1. A modular inserter assembly 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, said modular inserter assembly comprising:
a depth stop and a modular inserter tip releasably attached to said depth stop, said modular inserter tip including a cage attachment surface for releasable attachment to said interbody fusion cage, said depth stop including a movable stop axially movable relative to said 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 first location on said modular inserter tip by a selectively adjustable first distance, said modular inserter tip having a distal end and a proximal end, said distal end comprising a pair of flexible latches terminating in a pair of bilateral hooks for releasable attachment to said interbody fusion cage, said first location on said modular inserter tip is said cage attachment surface, each of said hooks comprising a cam cooperatively engageable with a movable portion of said depth stop to cause movement of said hooks toward each other in a manner to allow release from said interbody fusion device.
