Abstract:
1. A method of treating a disc that is leaking nucleus pulposus through at least one defect in the annulus fibrosus, comprising: 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 thrombin, wherein at least a portion of the fibrin forms after injection, wherein the fibrinogen, the thrombin or both has been reconstituted with a solution containing at least one additive, wherein a corticosteroid is absent from the fibrin sealant injected into the disc, and wherein the injecting occurs by inserting an introducer needle having a tip into the intra-discal space to a position adjacent to the at least one defect, inserting a second needle or a polymeric catheter through the introducer needle up to but not beyond the tip of the introducer needle, and injecting the fibrin sealant through the second needle or polymeric catheter.
