Bone anchorage system
A bone anchoring system having a flexible member with a first end and a second end opposite the first end. A fastener provided at a first end of the flexible member for retaining the flexible member within a bone. A rigid member is provided to ensure movement or pull-through of the flexible member does not occur.
1. A bone anchoring system comprising:
a. a flexible member having a first end and a second end opposite the first end;
b. a fixation element connected to the first end of the flexible member;
c. a rigid member configured to be disposed adjacent a bone interface, wherein the rigid member is capable of withstanding lateral tension applied via the flexible member; and
d. a tensioning mechanism coupled with the flexible member, the tensioning mechanism capable of providing fixation to the flexible member with limited access;
and wherein the flexible member travels in a transverse direction to a vertebra for at least a portion of the flexible member proximate the first end of the flexible member.
2. The bone anchoring system of claim 1 , wherein the rigid member is selected from the group consisting of a grommet, a cortical button, a toggle and a reverse locking plate.
3. The bone anchoring system of claim 1 , further comprising a cannulated bone screw capable of receiving the flexible member therein.
4. The bone anchoring system of claim 1 , wherein the tensioning mechanism includes a self-ratcheting tightening mechanism.
5. The bone anchoring system of claim 1 , wherein the tensioning mechanism is a fixation collar.
6. The bone anchoring system of claim 5 , wherein the fixation collar includes a base portion and two arms extending from the base portion, and a slot located on each of the two arms, wherein each of the slots are configured to receive the flexible member therein.
7. A bone anchoring system comprising:
a. a flexible member having a first end and a second end opposite the first end;
b. a fixation element connected to the first end of the flexible member;
c. a rigid member configured to be disposed adjacent a bone interface, wherein the rigid member is capable of withstanding lateral tension applied via the flexible member; and
d. a tensioning mechanism coupled with the flexible member, the tensioning mechanism capable of providing fixation to the flexible member with limited access;
and wherein the flexible member travels from the cortical bone of a pedicle of a patient's vertebral body towards a far cortical bone of a lateral aspect of the patient's vertebral body.
8. The bone anchoring system of claim 7 , wherein the rigid member is selected from the group consisting of a grommet, a cortical button, a toggle and a reverse locking plate.
9. The bone anchoring system of claim 7 , further comprising a cannulated bone screw capable of receiving the flexible member therein.
10. A vertebral anchoring system comprising:
a. a flexible member having a first end and a second end opposite the first end, the flexible member capable of being positioned transversely across a vertebra;
b. a fixation element connected to the first end of the flexible member;
c. a rigid member disposed adjacent an interface between the vertebra and the flexible member, wherein the rigid member is capable of withstanding lateral tension applied via the flexible member;
d. an axial rod positioned exterior to a vertebra; and
e. a coupler capable of coupling the flexible member to the rod;
and wherein the flexible member travels in a transverse direction to a vertebra for at least a portion of the flexible member proximate the first end of the flexible member.
11. The vertebral anchoring system of claim 10 , wherein the flexible member travels from the cortical bone of a pedicle of a patient's vertebral body towards a far cortical bone of a lateral aspect of the patient's vertebral body.
12. The vertebral anchoring system of claim 10 , wherein the fixation element is selected from the group consisting of a grommet, a cortical button and a toggle.
13. The vertebral anchoring system of claim 10 , wherein the coupler is a fixation collar.
14. The vertebral anchoring system of claim 13 , wherein the fixation collar includes a base portion and two arms extending from the base portion, and a slot located on each of the two arms, wherein each of the slots are configured to receive the flexible member therein.
15. The vertebral anchoring system of claim 10 , wherein the coupler is a self-ratcheting collar.
16. A vertebral anchoring system comprising:
a. a flexible member having a first end and a second end opposite the first end, the flexible member capable of being positioned transversely across a vertebra;
b. a fixation element connected to the first end of the flexible member;
c. a rigid member disposed adjacent an interface between the vertebra and the flexible member, wherein the rigid member is capable of withstanding lateral tension applied via the flexible member;
d. an axial rod positioned exterior to a vertebra; and
e. a coupler capable of coupling the flexible member to the rod;
and wherein the flexible member travels from one a first pedicle of a patient to a point anterior of the vertebral foramen of the patient and then towards a second pedicle of the patient.
17. The vertebral anchoring system of claim 16 , wherein the fixation element is selected from the group consisting of a grommet, a cortical button and a toggle.
18. The vertebral anchoring system of claim 16 , wherein the coupler is a fixation collar.
19. The vertebral anchoring system of claim 18 , wherein the fixation collar includes a base portion and two arms extending from the base portion, and a slot located on each of the two arms, wherein each of the slots are configured to receive the flexible member therein.
20. The vertebral anchoring system of claim 16 , wherein the coupler is a self-ratcheting collar.
