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.
Claims18
A method of implanting an intervertebral fusion device, the method comprising the steps of:
- inserting an elongate member into an intervertebral space that is defined by an upper vertebral body and a lower vertebral body, wherein an upper surface of the elongate member bears against the upper vertebral body and a lower surface of the elongate member bears against the lower vertebral body;
- and
- moving a body such that a concave inner surface of the body moves along a curved path defined by a convex outer surface of a component that is complementary to the concave inner surface of the body, wherein the component is disposed between the body and the elongate member and separate from both the body and the elongate member.
An intervertebral fusion device comprising:
- an elongated intervertebral implant configured to be inserted into an intervertebral space, such that upper and lower surfaces of the implant abut upper and lower vertebral bodies, respectively, to define the intervertebral space;
- a body that defines a concave inner surface;
- and
- a component disposed between the implant and the body, wherein the component defines a convex outer surface that is complementary to the concave inner surface of the body,
- wherein the concave inner surface of the body is movable along a curved path defined by the convex outer surface of the component.
