Abstract
An expandable interbody fusion device includes superior and inferior plates that are configured to receive a sequentially inserted stack of expansion members or wafers in interlocking engagement. The superior and inferior plates have openings therethrough in communication with aligned holes through the wafers for receipt and containment of bone graft to promote fusion between opposing vertebral bodies. One of said superior and inferior endplates has a multi-contoured opening extending therethrough.
