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 therebetween. 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.
Claims20
An implant device for grafting together adjacent bony structures of a body, said implant device comprising:
- a first endplate configured to be fixed to a first vertebral body;
- a second endplate configured to be fixed to a second vertebral body;
- a rod having a first end, a second end and a longitudinally extending body disposed between the first and second ends, wherein at least a portion of the rod first end is curvilinear in shape and at least a portion of the rod second end is curvilinear in shape, and the first and second curvilinear ends are rotatably disposed between the first endplate and the second endplate, a length of the longitudinally extending body being higher than a width of the longitudinally extending body so as to allow the first endplate to translate laterally relative to the second endplate;
- and
- a fusion shaft member disposed on the rod body.
An implant device for grafting together adjacent bony structures of a body comprising:
- an endplate having a retaining structure for securing the endplate to one of the bony structures;
- a rod, wherein at least a portion of a rod end is curvilinear in shape and the curvilinear end portion is disposed in a portion of the endplate to fixedly interconnect the bony structures wherein the rod includes a longitudinally extending body whose length is greater than a width of the longitudinally extending body;
- and
- a fusion shaft member partially surrounding the rod, and including a plurality of outwardly extending extension members.
