Abstract
An expandable intervertebral fusion implant includes a pair of shells having mating surfaces which resist shifting when the parts are assembled. The shells have opposed legs provided with teeth which permit the shells to be ratcheted outward in a non-parallel fashion after they have been placed between spinal elements.
