Claim:
1. An intervertebral fusion device comprising: an elongated member having a leading end, a trailing end, and a central vertical through hole that extends therethrough, the elongated member further including an upper surface configured to grip an upper vertebral endplate, and a lower surface opposite the upper surface along a vertical direction, the lower surface configured to grip a lower vertebral endplate; a plate including a concave inner plate surface, an outer plate surface opposite the inner plate surface, and a through hole that extends from the outer plate surface to the inner plate surface; a component interposed between the inner plate surface and the trailing end of the elongated member, the component being separate from both the plate and the elongated member, the component including i) an inner component surface that faces the trailing end of the elongated member and ii) a convex outer component surface that faces the inner plate surface; and a threaded post that extends through the through hole of the plate, wherein the convex outer component surface and the concave inner plate surface are complementary to each other so that the plate is movable about the component.
