摘要:
A single to multi-level spine plate has configured bone screw bores that cooperate with bone screws to retain a bone screw in a determinative position. In one form, the determinative position is a self-capture position wherein the bone screw is retained without the aid of any additional bone screw retention device. In another form, the determinative position is a limited angulation orientation of a bone screw relative to the spine plate. This limited angulation may be different for end plate bone screw bores than for middle plate bone screw bores. The bone screw bores may be configured to prohibit angulation once set. In another form, the determinative position is the reception of a cooperating bone screw at a centroid of the bone screw bore when installed.
