Abstract

Occipital plate systems are described. The occipital plate systems include an occipital plate having an upper portion and lower portion. The lower portion can include an opening for receiving one or more lateral members therethrough. The lateral members include top and/or side apertures for receiving lateral connectors that are attached to polyaxial screw receiving members. The occipital plate systems can also include low-profile clamping arms that are operably attached to an occipital plate via an extension member and articulating joint member. The clamping arms, along with tension cables attached intermittently along its length, can be used in addition to or instead of screws and hooks to secure an occipital plate system to vertebrae.

First claim

What is claimed is:

1. An occipital plate system comprising:
an occipital plate comprising a body having an upper portion and a lower portion extending from the upper portion, the lower portion including an opening;
a lateral member received through the opening, the lateral member including a top aperture;
a rod accepting component having a top opening, wherein the rod accepting component is configured to be received in the top aperture and includes a polyaxial screw head receiver; and
a lateral connector configured to be received in the top opening or the side aperture,
wherein the lateral member is rotatable about a first axis and translatable along the first axis such that the lateral member is adjustable relative to the occipital plate.

2. The system of claim 1 , wherein the occipital plate is tapered such that it has a thickness that is greater near the lower portion of the occipital plate.

3. The system of claim 1 , wherein the upper portion of the occipital plate includes a plurality of holes configured to receive one or more fasteners.

4. The system of claim 3 , wherein the plurality of holes are arranged in a diamond-shaped pattern.

5. The system of claim 1 , wherein the lateral connector comprises an uncurved arm attached to the polyaxial screw head receiver positioned in the top aperture in the lateral member.

6. The system of claim 1 , wherein the lateral connector comprises a curved arm attached to the polyaxial screw head receiver positioned in the top aperture in the lateral member.

7. The system of claim 1 , wherein the lateral member further includes a side aperture for receiving the lateral connector.

8. An occipital plate system comprising:
an occipital plate comprising a body having a diamond-shaped upper portion and a lower portion extending from the upper portion, wherein the lower portion includes an opening;
a lateral member received through the opening, the lateral member extending from a first end to a second end, the lateral member including a first top aperture and a second top aperture; and
a rod accepting component received in each of the first and second top apertures, each rod accepting component configured to secure a lateral connector thereto, wherein the rod accepting components each include a polyaxial screw head receiver,
wherein the lateral member is rotatable and translatable such that the lateral member is adjustable relative to the occipital plate.

9. The system of claim 8 , wherein the occipital plate is tapered such that it has a thickness that is greater near the lower portion of the occipital plate.

10. The system of claim 8 , wherein the upper portion of the occipital plate includes a plurality of holes.

11. The system of claim 10 , wherein the plurality of holes are arranged in a diamond-shaped pattern.

12. The system of claim 8 , wherein the lateral connector comprises an uncurved arm attached to the polyaxial screw head receiver positioned in one of the first or the second top aperture in the lateral member.

13. The system of claim 8 , wherein the lateral connector comprises a curved arm attached to a polyaxial screw head receiver positioned in the one of the first or the second top aperture in the lateral member.

14. The system of claim 8 , wherein the lateral member further includes a side aperture for receiving the lateral connector.

15. An occipital plate system comprising:
an occipital plate comprising a body having a diamond-shaped upper portion and a lower portion extending from the upper portion, the upper portion including at least three holes and the lower portion including an opening;
at least three fasteners, each fastener extending through one of the holes of the at least three holes of the occipital plate;
a lateral member received through the opening, the lateral member extending from a first end to a second end, the lateral member including a first top aperture and a second top aperture;
a plurality of rod accepting components, each rod accepting component received in one of the first and second top apertures, respectively, wherein each rod accepting component includes a polyaxial screw head receiver; and
a plurality of lateral connectors, each lateral connector coupled to a respective one of the rod accepting components,
wherein the lateral member is rotatable and translatable such that the lateral member is adjustable relative to the occipital plate.

16. The system of claim 15 , wherein the occipital plate is tapered such that it has a thickness that is greater near the lower portion of the occipital plate.

17. The system of claim 15 , wherein the lateral member further includes a side aperture for receiving one of the plurality of lateral connectors.
