Methods and apparatus for stabilizing bone
In some embodiments, a method comprises disposing a portion of a flexible fastening band into contact with a first bone portion and into contact with a second bone portion. The portion of the flexible fastening band having a substantially uniform shape configured to substantially compliment a shape of the first bone portion and a shape of the second bone portion. The method further includes inserting the portion of the flexible fastening band into a fastener and advancing the portion of the flexible fastening band through the fastener until the first bone portion and the and the second bone portion are stabilized.
1. An apparatus, comprising:
an elongate body comprising a proximal end portion, a first portion, a second portion, and a distal end portion, wherein the second portion comprises a gear rack; and
a fastening mechanism comprising a ratchet,
wherein the fastening mechanism is configured to receive the proximal end portion, the first portion, and at least a portion of the second portion to engage the ratchet with a gear of the gear rack,
wherein the fastening mechanism is separately formed from the elongate body; and
a drill configured to form a lumen in an articular process.
2. The apparatus of claim 1 , wherein the second portion comprises a substantially cuboidal shape.
3. The apparatus of claim 1 , wherein the distal end portion is substantially circular in shape.
4. The apparatus of claim 1 , wherein the distal end portion comprises a cross-sectional dimension greater than a cross-sectional dimension of the second portion.
5. The apparatus of claim 1 , wherein the fastening mechanism comprises a cross-sectional dimension greater than a cross-sectional dimension of the second portion.
6. The apparatus of claim 1 , wherein the gear rack comprises wedge shaped gears.
7. The apparatus of claim 1 , wherein the gear rack comprises gears configured to displace the ratchet in only one direction.
8. The apparatus of claim 1 , further comprising a spacer comprising an aperture configured to receive the proximal end portion.
9. The apparatus of claim 1 , wherein the second portion forms an arc.
10. The apparatus of claim 1 , wherein the fastening mechanism is configured to be disposed toward the superior articular process and the distal end portion is configured to be disposed toward the inferior articular process.
11. The apparatus of claim 1 , wherein the second portion comprises a convex surface and a concave surface, wherein the gear rack is disposed on the convex surface.
12. The apparatus of claim 1 , wherein the second portion comprises an upper surface and a lower surface, wherein the gear rack is disposed on the lower surface.
13. The apparatus of claim 1 , wherein the fastening mechanism comprises a concave surface.
14. The apparatus of claim 1 , wherein the fastening mechanism comprises notches, wherein the fastening mechanism is configured to be grasped by a user.
15. The apparatus of claim 1 , wherein the fastening mechanism comprises a lumen.
16. The apparatus of claim 1 , further comprising a surgical tool configured to receive the fastening mechanism without obstructing a lumen of the fastening mechanism.
17. The apparatus of claim 1 , wherein the elongate body and the fastening mechanism are configured to stabilize a superior articular process and an inferior articular process.
18. The apparatus of claim 1 , wherein the ratchet engages more than one gear of the gear rack.
19. A method of treating bone portions, the method comprising:
forming a lumen in a first bone portion;
forming a lumen in a second bone portion;
disposing the proximal portion of the elongate body of claim 1 through the lumen of the first bone portion and through the lumen of the second bone portion; and
advancing the proximal portion, the first portion, and at least the portion of the second portion into the fastening mechanism of claim 1 to engage the ratchet with the gear of the gear rack.
20. The method of claim 19 , wherein the first bone portion comprises a superior articular process and the second bone portion comprises an inferior articular process.
