A bone screw retention system is provided for a plate which defines a plurality of transversely extending bores that are configured to receive a bone screw for engaging the plate to the cervical spine. One or more retention members, having an elliptical, arcuate, straight, or other shape, can be positioned therein a cavity of the plate such that portions of the retention member(s) extend into a portion of an upper region of each bore to retain a bone screw therein.
