An intervertebral spacer device includes first and second plates having plate surfaces, the first and second plates being spaced from one another with inner ones of the plate surfaces opposing one another and external ones of the plate surfaces facing in opposite directions. The spacer device includes at least one domed arch strip spring disposed between the inner surfaces of the first and second plate members for counteracting compressive loads applied to the external surfaces of the first and second plates. The at least one domed arch strip spring has lateral ends that are coupled with the first plate and a curvate central portion that is maintained adjacent the inner surface of the second plate.
