Device and method for reinforcement of a facet
In some embodiments, a device for reinforcement of a facet joint is provided. The device comprises a lumen configured to receive a fastener member. In some embodiments, a second segment comprises a second lumen configured to receive a fastener member or fastener. In some embodiments, kits are provided with a fastener member and a facet reinforcement device. Methods are also provided for treating a spine. In some embodiments, the fastener member is placed through both articular processes of a facet joint and a facet reinforcement device.
1. A device for reinforcing a facet joint, comprising:
a proximal surface, a distal surface, and a first side surface and a second side surface, the first side surface and the second side surface extending between the proximal surface and the distal surface,
a first securing segment comprising a first lumen extending from the proximal surface to the distal surface, the first lumen adapted for receiving a first fastener member;
a second securing segment comprising a second lumen extending from the first side surface to the second side surface, the second lumen adapted for receiving a second fastener member; and
a central portion between the first securing segment and the second securing segment.
2. The device of claim 1 , wherein a longitudinal axis of the first securing segment is disposed at an angle relative to a longitudinal axis of the second securing segment.
3. The device of claim 1 , wherein a plane of the first securing segment is not parallel to a plane of the second securing segment.
4. The device of claim 1 , wherein the second securing segment comprises at least two lumens.
5. The device of claim 1 , further comprising the first fastener member.
6. The device of claim 1 , wherein at least one surface of the device comprises a groove to mechanically interfit with the first fastener member.
7. The device of claim 1 , wherein at least one surface of the device comprises a feature to mechanically interfit with an insertion tool.
8. The device of claim 1 , wherein the first securing segment is configured for placement on an outer facet surface of a facet and the second securing segment is configured for placement on a vertebral structure, remote from the outer facet surface of the facet.
9. The device of claim 1 , wherein at least a portion of one surface of the device is malleable.
10. The device of claim 1 , wherein at least a portion of one surface of the device is roughened.
11. The device of claim 1 , wherein the device is made of multiple materials in combination.
12. The device of claim 1 , wherein the central portion comprises a bend.
13. A facet reinforcement device, comprising:
an inferior end and a superior end;
a first securing portion toward the inferior end and a second securing portion toward the superior end, the first securing portion and the second securing portion connected to each other by a central portion, wherein the first securing portion and the second securing portion lie on different planes; and
the first securing portion comprising a first lumen and the second securing portion comprising a second lumen, wherein a first fastener inserted into the first lumen extends transverse to a proximal surface of the inferior end, wherein a second fastener inserted into the second lumen extends transverse to a side surface of the superior end.
14. The device of claim 13 , wherein the angle between the different planes is between 30 and 150 degrees.
15. The device of claim 13 , wherein the angle between the different planes is between 60 and 105 degrees.
16. The device of claim 13 , wherein the first lumen comprises a first longitudinal axis and the second lumen comprises a second longitudinal axis, wherein the first longitudinal axis and the second longitudinal axis are perpendicular.
17. The device of claim 13 , wherein the first lumen comprises a first longitudinal axis and the second lumen comprises a second longitudinal axis, wherein the first longitudinal axis is angled relative to the second longitudinal axis.
18. A facet reinforcement device, comprising:
a proximal surface and a distal surface;
a first securing portion comprising a first lumen extending between the proximal surface and the distal surface, the first lumen configured to receive a fastener member;
a second securing portion comprising a second lumen; and
a central portion between the first securing portion and the second securing portion, wherein the central portion is twisted to provide an offset or an angulation of the first securing portion relative to the second securing portion, wherein a transverse dimension of the proximal surface is greater at the first securing portion than the second securing portion.
19. The device of claim 18 , wherein the first securing portion is offset in multiple dimensions from the second securing portion.
20. The device of claim 18 , wherein a longitudinal axis of the first lumen and a longitudinal axis of the second lumen are angled.
