Title: Expandable intervertebral fusion implant having improved stability

Abstract: An expandable intervertebral implant includes two separate shells having corrugated mating surfaces which resist compression and shifting when the parts are distracted by a special installation tool. The shells include two planar wings which provide a large bearing area against adjacent vertebral endplates to prevent the implant from sinking into cancellous bone.
