Abstract
An apparatus for surgical fusion of a cranio-cervical junction includes a plate member, where the plate member includes a bottom portion configured to be secured to a cranium; a top portion including a plurality of perforations extending therethrough configured to promote bone growth, wherein the top portion and the bottom portion define a graft accommodation space; and first and second side portions coupled to the top and bottom portions on first and second sides of the graft accommodation space. The first side portion is configured to receive a first support rod and the second side portion is configured to receive a second support rod.
Claims19
An apparatus for surgical fusion of a cranio-cervical junction, comprising:
- a plate member comprising:
- a bottom portion configured to be secured to a cranium;
- a top portion including a plurality of perforations extending therethrough configured to promote bone growth, wherein the top portion and the bottom portion define a graft accommodation space;
- and
- first and second side portions coupled to the top and bottom portions on first and second sides of the graft accommodation space;
- wherein the first side portion is configured to receive a first support rod and the second side portion is configured to receive a second support rod.
A cranio-cervical fixation system, comprising:
- a first spinal rod configured to be coupled to a vertebral body;
- a second spinal rod configured to be coupled to the vertebral body;
- and
- a plate member configured to be secured to a cranium and receive the first and second spinal rods to provide a desired fixation of the vertebral body relative to the cranium;
- wherein the plate member defines a graft accommodation space between a top portion of the plate member and the cranium, wherein the top portion includes a plurality of apertures formed therein and wherein the graft accommodation space is configured to receive bone growth material to fuse to the cranium.
A plate member usable in a fixation system to fuse a cranium to a vertebral body, wherein the plate member is configured to receive one or more spinal rods, the plate member comprising:
- a body defining a graft accommodation space therein, the body further including:
- a generally planar bottom surface;
- a generally planar rear surface extending upward from the bottom surface;
- and
- a contoured top surface providing a smooth contoured peripheral top of the plate member extending from the bottom and rear surfaces;
- and
- a top portion defining at least a portion of the top surface, wherein the top portion further defines a plurality of apertures extending therethrough and covering an area extending above the graft accommodation space.
