Nubbed plate

A method of implanting an intervertebral fusion device, the method comprising the steps of:

• inserting a leading end of an elongated member into an intervertebral space that is defined by an upper vertebral endplate and a lower vertebral endplate, such that an upper surface of the elongated member grips the upper vertebral endplate, and a lower surface opposite the upper surface along a vertical direction grips the lower vertebral endplate, wherein the elongated member further defines a trailing end and a central vertical through hole that extends therethrough;
• and
• moving a concave inner plate surface of a plate about a convex outer component surface of a component, the convex outer component surface being complementary to the concave inner plate surface, wherein the component is interposed between the inner plate surface and the trailing end of the elongated member and separate from both the plate and the elongated member, such that an inner component surface of the component faces the trailing end of the elongated member,
• wherein a threaded post extends through a through hole of the plate that extends from the inner plate surface to an outer plate surface that is opposite the inner plate surface.
