    at least two bone screw receiving holes extending through said plate from said upper surface through said lower surface, each of said bone screw receiving holes having a central longitudinal axis and being adapted to receive a bone screw to attach for engaging said plate to the cervical spine; and

    a lock adapted to overlie at least a portion of said at least two bone screw receiving holes, said lock having an elongated segment having a width, a length longer than said width, and a surface adapted to bear against said plate, said lock being adapted to engage said plate and being adapted to retain at least two bone screws to said plate when said length of said elongated segment is generally transverse to the longitudinal axis of said plate.
