A modular intervertebral prosthesis system includes first and second baseplates
and an insert designed to mate to the baseplates. The baseplates include a mounting
section and a intervertebral section extending away from the mounting section generally
perpendicular thereto. The intervertebral section has at least one aperture passing
therethrough. When installed, the insert is disposed between the intervertebral
sections of the baseplates and faces the apertures. In this way, the insert is
not insulated from the vertebral members, thereby allowing for osteoinduction,
osteoconduction, and/or osteointegration, if desired. The insert may take the form
of an articulating-type insert or a fusion-type insert, with the baseplates being
operative with both types of inserts. After installation of the insert between
the baseplates, the insert may be readily removed, at least initially.
