Abstract
A separate nub component between the plate and an intervertebral fusion cage, wherein the nub is attached to the plate. The nub lessens the undesired pivotal movement of the plate. It is believed that when the nub fits snugly between the endplates of the adjacent vertebral bodies, it acts as a stop against the undesired pivotal movement of the plate.
Claims19
An intervertebral fusion device comprising:
- a) an intervertebral fusion cage having a leading end, a trailing end, an upper surface configured to contact an upper vertebral endplate, and a lower surface opposite the upper surface, the lower surface configured to contact a lower vertebral endplate;
- b) a plate including an inner plate surface and 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;
- c) a separate component interposed between the plate and the trailing end of the cage, the separate component being separated from each of the plate and the intervertebral fusion cage, the component including i) an inner component surface that faces the trailing end of the intervertebral fusion cage, ii) an outer component surface that faces the inner plate surface, and iii) a pair of opposed terminal ends of the outer component surface, wherein the outer component surface defines a convex path from one of the terminal ends to the other of the terminal ends;
- and
- a threaded post that extends through the through hole of the plate.
