Abstract

A bone support assembly comprising a support plate, bone fasteners, and a bone fastener cover assembly. The support plate comprises a fixed base portion comprising base apertures, and a slot portion comprising slot-shaped apertures. The bone fasteners are disposed in ones of the base apertures and the slot-shaped apertures, the bone fasteners and the support plate, in combination, being adapted and configured for holding the support plate to bone material. The bone fastener cover assembly comprises a cover plate, and at least one cover plate fastener effective to fasten the cover plate to the support plate. The cover plate and support plate, in combination, accommodate both longitudinal and transverse sliding movement of the cover plate along the top surface of the support plate to thereby cover and uncover ones of the apertures, having bone fasteners therein, while the cover plate is attached to the support plate.
