Injection of fibrin sealant in the absence of corticosteroids in spinal applications
A method and kit for treating a disc that is leaking nucleus pulposus through at least one defect in the annulus fibrosus. The method includes injecting a fibrin sealant into the disc to reduce at least a portion of the at least one defect, wherein the fibrin sealant injected into the disc comprises fibrinogen and an activating compound, wherein at least a portion of the fibrin forms after injection, with the proviso that a corticosteroid is absent from the fibrin sealant injected into the disc.
1. A method of treating a disc and providing improved pain relief for discogenic and radicular pain, comprising:
advancing a hypodermic needle through skin percutaneously, through the annulus fibrosus and into the nucleus pulposus by piercing the skin, the annulus fibrosus and into the nucleus pulposus with the hypodermic needle;
inserting a fluid delivery tube into the hypodermic needle up to but not beyond the distal tip of the hypodermic needle;
injecting a fibrin sealant into the disc through the hypodermic needle and the fluid delivery tube to reduce at least a portion of the at least one defect, wherein the fibrin sealant injected into the disc comprises calcium ions, fibrinogen and thrombin, wherein at least a portion of the fibrin forms after injection,
with the proviso that a corticosteroid is absent from the fibrin sealant injected into the disc and wherein the fibrin sealant provides improved pain relief as compared to fibrin sealant containing a corticosteroid.
2. A method of treating a disc and providing improved pain relief for discogenic and radicular paint, comprising:
advancing a rigid hypodermic needle through skin percutaneously, through the annulus fibrosus and into the nucleus pulposus by piercing an un-pierced portion of the skin, an un-pierced portion of the annulus fibrosus and into the nucleus pulposus with the hypodermic needle;
inserting a fluid delivery tube into the hypodermic needle up to but not beyond the distal tip of the hypodermic needle;
injecting a fibrin sealant into the disc through the rigid hypodermic needle and the fluid delivery tube to reduce at least a portion of the at least one defect, wherein the fibrin sealant injected into the disc comprises calcium ions, fibrinogen and thrombin, wherein at least a portion of the fibrin forms after injection,
with the proviso that a corticosteroid is absent from the fibrin sealant injected into the disc and wherein the fibrin sealant provides improved pain relief as compared to fibrin sealant containing a corticosteroid,
with the proviso that neither the nucleus pulposus nor the annulus fibrosus has been heated.

4. The method of claim 1 , wherein no portion of the nucleus pulposus has been removed by surgery.
5. The method of claim 1 , wherein the at least one defect is a tear or fissure in the annulus fibrosus.
6. The method of claim 1 , wherein normal physiologic hydrostatic pressure in the disc is restored or normal disc height is restored or both.
7. The method of claim 1 , wherein the fibrinogen is autologous.
8. The method of claim 1 , wherein the injection is performed using a dual barrel syringe.
9. The method of claim 1 , wherein the fibrinogen and thrombin are injected sequentially and at least partially mix in the disc.
10. The method of claim 1 , wherein the disc is injected with the fibrin sealant at multiple positions in the disc.
11. The method of claim 1 , wherein the injecting occurs by injecting the fibrin sealant through the fluid delivery tube.
12. The method of claim 1 , wherein the disc is a lumbar disc.
13. The method of claim 1 , wherein the disc is a thoracic disc.
14. The method of claim 1 , wherein the disc is a cervical disc.
15. The method of claim 1 , wherein a contrast agent is injected either before the fibrin sealant, with the fibrin sealant, or after the fibrin sealant has been injected.
16. The method of claim 1 , wherein a local anesthetic is injected with the fibrin sealant.
17. The method of claim 1 , wherein the discogenic and radicular pain is discogenic pain.
18. The method of claim 1 , wherein the discogenic and radicular pain is radicular pain.
19. The method of claim 2 , wherein the discogenic and radicular pain is discogenic pain.
20. The method of claim 2 , wherein the discogenic and radicular pain is radicular pain.
21. The method of claim 1 , wherein the hypodermic needle and the fluid delivery tube both extend into the nucleus pulposus.
22. The method of 1 , wherein the hypodermic needle is at least 5 inches long.
23. The method of claim 1 , wherein the components of fibrinogen, calcium ions, and thrombin are injected simultaneously.
24. A method of treating a disc and providing improved pain relief for discogenic and radicular pain, comprising:
advancing a hypodermic needle through skin percutaneously, through the annulus fibrosus and into the nucleus pulposus by piercing the skin, the annulus fibrosus and into the nucleus pulposus with the hypodermic needle;
inserting a fluid delivery tube into the hypodermic needle up to but not beyond the distal tip of the hypodermic needle;
injecting a fibrin sealant into the disc through the hypodermic needle and the fluid delivery tube to reduce at least a portion of the at least one defect, wherein the fibrin sealant injected into the disc comprises calcium ions, fibrinogen and thrombin, wherein at least a portion of the fibrin forms after injection,
