An implantable, spinal, vertebral replacement device comprises a tubular cage for fitting into a space left by a missing vertebral body and for optionally retaining bone graft material. First and second transverse plates are respectively positioned at opposed ends of the tubular cage for supporting the respective cage ends and for pressing a plate face against an adjacent vertebral body in spinal column-supporting relation. The transverse plates are each joined in transverse relation to at least one vertebral attachment plate which, in use, extends generally parallel to the spine. The vertebral attachment plate defines screw holes for screw securance to at least one vertebral body adjacent to the space. Preferably, one or more vertebral attachment plates are connected to the pair of adjacent vertebral bodies that bracket the space left by the missing vertebral body.

A floor section assembly having a post anchor built into one of the floor panels for use with portable sectionalized flooring suitable for a volleyball court or the like is disclosed. The post anchor includes a base assembly attached to the undersurface of one of the panels and is coupled to a plurality of adjacent panels by tubes attached to the undersurface of the panels and coupled together by a rigid member extending through aligned tubes. This structure provides a broad base of support for the post carrying a volleyball net which can absorb moments placed on the post without the need for connecting the post to the base on which the flooring is assembled.
