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.
Claims19
An implant device for grafting together adjacent bony structures of a body comprising:
- an endplate having an inner disc portion and outer ring portion spaced from the inner disc portion by a connecting wall disposed therebetween, wherein an interior surface of the endplate includes a retaining structure for securing the endplate to one of the bony structures, and the endplate inner disc portion has an integrally formed socket;
- a ball joint rod having a longitudinally extending body and an end, wherein at least a portion of the ball-joint rod end is curvilinear in shape, and the curvilinear ball joint rod end is rotatably disposed in the endplate socket to fixedly interconnect the bony structures;
- and
- a fusion shaft member partially surrounding the body of the ball-joint rod, and the fusion shaft member includes a plurality of outwardly extending extension members.
An implant device for grafting together adjacent vertebral body structures of a spine comprising:
- an endplate having an inner disc portion and outer ring portion spaced from the inner disc portion by a connecting wall disposed therebetween, wherein an interior surface of the endplate includes a retaining structure and the endplate inner disc portion has an integrally formed socket, and the endplate is adapted to be secured to one vertebral body and another endplate is adapted to be secured to the adjacent vertebral body;
- a ball-joint rod having a longitudinally extending body and a first end and a second end, wherein at least a portion of each of the first ball-joint rod end and second ball-joint rod end is curvilinear in shape, and each of the curvilinear ball joint rod ends is rotatably disposed in the corresponding endplate socket to fixedly interconnect the vertebral bodies;
- and
- a fusion shaft member partially surrounding the body of the ball joint rod, and the fusion shaft member includes a plurality of outwardly extending extension members.
