Abstract

Disclosed are methods of spinal fixation involving application of a liquid medium which cures, hardens, polymerizes or otherwise serves to bind adjacent vertebrae together. The fixation which results from this binding may be temporary or essentially permanent in duration, and may be used to treat conditions or disease of the spine, such as inflammation, instability or fracture. In a preferred embodiment, the liquid medium comprises a low viscosity cyanoacrylate-based adhesive.

Claims

1. A method of immobilizing a portion of the spine, comprising the steps of identifying a joint between a first vertebra and a second vertebra which is to be immobilized, and administering an adhesive medium to bond at least a first superior articular process on the first vertebra to a corresponding first inferior articular process on the second vertebra, wherein the adhesive comprises cyanoacrylate and a radio opaque component.

2. A method of immobilizing a portion of the spine as in claim 1 further comprising the step of administering an adhesive medium to bond a second superior articular process on the first vertebra to a corresponding second inferior articular process on the second vertebra.

3. A method of immobilizing a portion of the spine as in claim 1, wherein the adhesive further comprises a polymerization inhibitor.

4. A method of immobilizing a portion of the spine as in claim 3, wherein the adhesive has a viscosity of no more than about 100 centipoise.

5. A method of immobilizing a portion of the spine as in claim 1, wherein the administration step is accomplished percutaneously.

6. A method of treating inflammation in the spine, comprising the steps of identifying a joint between a first vertebra and a second vertebra which is in the vicinity of an inflammation, and administering an adhesive medium comprising a radio opaque component to bond at least a first superior articular process on the first vertebra to a corresponding first inferior articular process on the second vertebra to temporarily immobilize the joint for a sufficient time to treat the inflammation, wherein the administering step is accomplished without a surgical cut down.

7. A method of treating inflammation in the spine as in claim 6, further comprising the step of administering an adhesive medium to bond a second superior articular process on the first vertebra to a corresponding second inferior articular process on the second vertebra.

8. A method of treating inflammation in the spine as in claim 6, further comprising the step of permitting the adhesive to dissipate following a treatment period of time.

9. A method of treating inflammation in the spine as in claim 8, wherein the treatment period is within the range of from about one week to about six months.

10. A method of treating inflammation in the spine as in claim 6, wherein the administering step is accomplished percutaneously.

11. A method of treating inflammation in the spine as in claim 6 wherein the adhesive further comprises cyanoacrylate.

12. A method of treating inflammation in the spine as in claim 6, wherein the joint is in the lumbar region of the spine.

13. A method of treating inflammation in the spine as in claim 6, wherein the joint is in the sacral region of the spine.

14. A method of treating inflammation in the spine as in claim 6, wherein the joint is in the L4-L5-S1 region of the spine.

15. A method of treating inflammation in the spine as in claim 6, wherein the administering step comprises expressing the adhesive near an edge of the joint, and permitting the adhesive to enter the joint by capillary action.

16. A method of treating inflammation in the spine as in claim 6, wherein the administering step comprises positioning a distal end of an injection needle within the joint and expressing adhesive under pressure within the joint.

17. A method of treating inflammation in the spine as in claim 6, wherein the administering step is accomplished under fluoroscopy.

18. A method of treating inflammation in the spine as in claim 6, further comprising the step of augmenting a spinal nucleus at the level of the joint.

19. A method of treating inflammation in the spine as in claim 6, further comprising the step of aligning the spine prior to the administering step.

20. A method of immobilizing a portion of the spine, comprising the steps of identifying a joint between a first vertebra and a second vertebra which is to be immobilized, and administering a thin film of adhesive medium within the joint to bond at least a first superior articular process on the first vertebra to a corresponding first inferior articular process on the second vertebra, wherein the adhesive medium comprises a radio opaque component.
