Abstract

A spinal fixation device for securing to a spine includes a body having one or more longitudinal members extending between a pair of wedge members. Each wedge member defines one or more openings therethrough for the reception of a bone screw. The wedge members are disposed on opposite ends of the one or more longitudinal members. One of the wedge members is positionable within a first intervertebral space and the other wedge member is positionable within a second intervertebral space. The one or more longitudinal members define a length that spans one or more vertebrae. The one or more longitudinal members are positionable within the one or more vertebrae when the wedge members are positioned within the respective first and second intervertebral spaces to maintain the body in a minimal profile orientation relative to the spine.

Claims

1. A method of securing a spinal fixation device to an anterior portion of a spine, comprising:

providing the spinal fixation device having a body including two longitudinal members extending between a pair of wedge members;

forming two recesses within at least one vertebra of the spine;

positioning the two longitudinal members at least partially within the two recesses;

positioning a first one of the pair of wedge members at least partially in a first intervertebral space defined between adjacent end faces of adjacent vertebrae of the spine;

positioning a second one of the pair of wedge members at least partially in a second intervertebral space defined between adjacent end faces of adjacent vertebrae of the spine; and

securing the spinal fixation device to the anterior portion of the spine so that the spinal fixation device is in a minimal profile orientation relative to the anterior portion of the spine.

2. The method of claim 1, further including:

forming the two recesses along a plurality of contiguous vertebrae of the spine; and

positioning the two longitudinal members at least partially within the two recesses along each of the plurality of contiguous vertebrae.

3. The method of claim 1, further including securing at least one of the pair of wedge members to at least one second vertebra of the spine with at least one bone screw, the at least one second vertebra being adjacent to the at least one vertebra.

4. The method of claim 1, further including spanning the two longitudinal members along a plurality of vertebrae.

5. The method of claim 1, further including positioning the two longitudinal members within the two recesses in a zero profile orientation relative to the anterior portion of the spine.

6. The method of claim 1, further including positioning the two longitudinal members within the two recesses in a low profile orientation relative to the anterior portion of the spine.

7. The method of claim 1, further including positioning the two longitudinal members in parallel relation to each other within the at least one vertebra of the spine.

8. The method of claim 1, wherein forming the two recesses includes forming the two recesses in parallel relation to each other.

9. A method of securing a spinal fixation device to an anterior portion of a spine, comprising:

providing the spinal fixation device having a body including at least one longitudinal member extending between a pair of wedge members;

forming at least one recess within at least one vertebra of the spine;

positioning the at least one longitudinal member at least partially within the at least one recess;

positioning a first one of the pair of wedge members at least partially in a first intervertebral space defined between adjacent end faces of adjacent vertebrae of the spine;

positioning a second one of the pair of wedge members at least partially in a second intervertebral space defined between adjacent end faces of adjacent vertebrae of the spine;

positioning the second one of the pair of wedge members longitudinally offset from the first one of the pair of wedge members; and

securing the spinal fixation device to the anterior portion of the spine so that the spinal fixation device is in a minimal profile orientation relative to the anterior portion of the spine.

10. The method of claim 9, further including:

forming the at least one recess along a plurality of contiguous vertebrae of the spine; and

positioning the at least one longitudinal member at least partially within the at least one recess along each of the plurality of contiguous vertebrae.

11. The method of claim 9, further including securing at least one of the pair of wedge members to at least one second vertebra of the spine with at least one bone screw, the at least one second vertebra being adjacent to the at least one vertebra.

12. The method of claim 9, further including spanning the at least one longitudinal member along a plurality of vertebrae.

13. The method of claim 9, further including positioning the at least one longitudinal member within the at least one recess in a zero profile orientation relative to the anterior portion of the spine.

14. The method of claim 9, further including positioning the at least one longitudinal member within the at least one recess in a low profile orientation relative to the anterior portion of the spine.

15. The method of claim 9, wherein forming the at least one recess within the at least one vertebra of the spine includes forming two recesses within the at least one vertebra, and wherein positioning the at least one longitudinal member at least partially within the at least one recess includes positioning two longitudinal members at least partially within the two recesses.

16. The method of claim 15, further including positioning the two longitudinal members in parallel relation to each other within the at least one vertebra of the spine.

17. The method of claim 15, wherein forming the two recesses includes forming the two recesses in parallel relation to each other.
