Methods and compositions for stabilization of a vertebra
View Patent ↗Compositions and methods are provided for stabilization and treatment of vertebrae, and in particular for stabilization and treatment of a vertebra having a fracture. Compositions are provided that stabilize and heal a fracture while facilitating healing and reducing the chance for re-injury to the vertebra or adjacent vertebra. Methods include elevation of the vertebra to facilitate healing under reduced pressure situations and include leverage points to elevate the fracture before or during composition insertion.
1. A method for treating a compression fracture in a vertebra of a vertebral column of a patient in need thereof, comprising:
providing at least three anchor points on the patient's vertebral column to elevate the compression fracture,
wherein two of the at least three anchor points are positioned on the same vertebra of the patient's vertebral column at a first vertebral level, and wherein a third anchor point is anchored into a posterior exterior surface of a spinous process at a second vertebral level different than the first vertebral level; and
administering an amount of a fracture treating material into the elevated compression fracture.
2. The method of claim 1 , wherein the at least three anchor points are provided on a posterior side of the patient's vertebral column.
3. The method of claim 1 , wherein at least one of the at least three anchor points is at or above the compression fracture.
4. The method of claim 1 , wherein at least one of the least three anchor points is at or below the compression fracture.
5. The method of claim 1 , wherein the at least three anchor points are moved simultaneously together to elevate the compression fracture.
6. The method of claim 1 , wherein the at least three anchor points are provided by pins selected from the group consisting of pedicle pins, extrapedicular pins, spinous process pins, and screws.
7. The method of claim 1 , wherein one of the at least three anchor points is hollow and is located in the same vertebra as the compression fracture.
8. The method of claim 7 , wherein the fracture treating material is administered into the elevated compression fracture through the hollow anchor point.
9. The method of claim 7 , wherein two of the at least three anchor points are hollow and wherein two of the at least two anchor points are located in the same vertebra as the compression fracture.
10. The method of claim 1 , wherein the fracture treating material is a modulus appropriate material.
11. The method of claim 10 , wherein the modulus appropriate material is composed of, or partially composed of, a demineralized bone matrix (DBM).
12. The method of claim 11 , further comprising a second modulus appropriate material to interdigitate with the DBM.
13. The method of claim 12 , further comprising a permanent or resorbable tissue adhesive.
14. The method of claim 10 , wherein the modulus appropriate material is selected from the group consisting of a hydrogel, an osmotic saline, and an albumin solution.
15. The method of claim 1 , wherein two of the at least three anchor points are oriented in a generally vertical plane relative to the vertebra.
16. A method for treating a compression fracture in a vertebra of a vertebral column of a patient in need thereof, comprising:
providing at least three anchor points on the patient's vertebral column to elevate the compression fracture,
wherein two of the at least three anchor points are positioned on the same vertebra of the patient's vertebral column;
a third anchor point disposed in a posterior exterior surface of a spinous process of a vertebra; and
administering an amount of a fracture treating material into the elevated compression fracture.
17. The method of claim 16 , wherein the at least three anchor points are moved simultaneously together to elevate the compression fracture.
18. The method of claim 16 , wherein the at least three anchor points are provided by pins selected from the group consisting of pedicle pins, extrapedicular pins, spinous process pins, and screws.
19. The method of claim 16 , wherein one of the at least three anchor points is hollow.
