A dynamic spine plate is formed with only a single row of bone screw bores that extend along a generally superior/inferior axis of the spine plate, providing a single-sided dynamic spine plate. The single-sided dynamic spine plate is formed from a plurality of spine plate components that are coupled dynamically to one another. This provides a modular, single-sided dynamic spine plate. The spine plate components are coupled dynamically to one another via socket and projection interfaces, the socket and projections interfaces incorporating resilient coupling and retention structures that allow limited movement of the spine plate components relative to one another. This provides for dynamic extension of the spine plate components relative to one another. The resilient coupling structure connects the spine plate components, providing a self-biased, snap fit coupling of spine plate components. Rotation stabilizers may be provide on the present single-sided dynamic spine plate that provide rotational stability to the spine plate in addition to the bone screws that will attach the spine plate to the vertebrae.
