Claim Text:
1. An implant assembly for use in spinal surgery, comprising: an intervertebral implant constructed of human allograft bone tissue, the implant having a body with upper and lower fixation surfaces adapted to abut at least partially resected surfaces of opposing vertebral bodies, the implant further including a keying feature protruding outwardly from at least one of the fixation surfaces and having an aperture therethrough, wherein the keying feature is adapted to be inserted into a prepared opening intersecting one of the resected surfaces and a foot print of the implant is sized such that the implant is positioned entirely within a foot print of the opposing vertebral bodies; a fixation element having an external threaded portion, the fixation element further having a cannulated opening extending longitudinally through the fixation element and a plurality of fenestrations extending from the external threaded portion to the cannulated opening to provide a pathway through which a flowable material can be introduced into the fixation element through the cannulated opening and flow out of the screw through the fenestrations, and wherein the fixation element is adapted to be inserted through the aperture of the keying feature of the intervertebral implant to compressively interconnect the intervertebral implant against the one of the resected surfaces.
