Abstract
A methodology for grafting together adjacent bony structures is provided using an implant device having an endplate with an inner disc portion and outer ring portion spaced from the inner disc portion by a connecting wall disposed there between. An endplate interior surface includes a retaining structure for securing the endplate to one of the bony structures, and endplate an exterior surface has an integrally formed socket. A ball-joint rod has a longitudinally extending body and an end, and at least a portion of the ball-joint rod end is curvilinear in shape. The curvilinear ball-joint rod end is rotatably disposed in the endplate socket to fixedly interconnect the bony structures.

A method of implanting an implant device for grafting together adjacent bony structures of a body comprising:
- attaching a first endplate having a first socket to a first vertebral body;
- attaching a second endplate having a second socket to a second vertebral body;
- and
- selecting one of a plurality of rods based on spacing between the attached endplates, the selected rod having first and second opposite ends;
- inserting the first and second ends of the selected rod to the respective first and second sockets of the attached endplates,
- wherein after inserting the selected rod to the attached endplates, further comprising attaching a fusion shaft to the selected rod in a snap-fit manner.
