Claims20
A modular implant device for the spine, the modular implant device for placement between two adjacent vertebrae, comprising:
- a first member sized to span at least a portion of a distance between the two adjacent vertebrae, the first member including a first body having a first upper surface and a first lower surface and a first opening formed through the body which extends from the first upper surface to the first lower surface, the first opening having a first height;
- a second member sized to span at least a portion of a distance between the two adjacent vertebrae, the second member including a second body having a second upper surface and a second lower surface and a second height, the second height being less than the first height, the second body being sized and configured to fit fully within the first opening;
- a first end cap having a first insert portion that fits within the first opening and a first rim portion which extends upwards from the insert portion, wherein the first rim portion further includes a first engagement surface for engaging an endplate portion of a first vertebral body of the two adjacent vertebrae, wherein when the second body is positioned fully within the first opening and the first insert portion of the first end cap is positioned within the first opening, the second upper surface is substantially in contact with at least a portion of a lower surface of the first insert portion, and
- a second end cap having a second insert portion that fits within the first opening and a second rim portion which extends downwards from the second insert portion, the second rim portion including a second engagement surface for engaging an endplate portion of a second vertebral body of the two adjacent vertebrae, wherein when the second body is positioned completely within the first opening and the second insert portion is positioned within the first opening, the second lower surface of the second body is substantially in contact with at least a portion of an upper surface of the second insert portion.
