Abstract: A unitary intervertebral device, having no moving components is provided for non-fusion articulation and fusion applications. The interbody articulating device allows for limited flexion and rotation between the implant and an adjacent vertebrae, helping to preserve or restore near-normal motion between adjacent vertebrae. Rotational motion is achieved through one or more protrusions incorporated into the spinal interbody device. In one articulating form, a first protrusion extends perpendicularly from one bearing surface of the interbody device to form a rotational protrusion, while at least a second protrusion extends from the opposite bearing surface of the interbody device to form a non-rotational protrusion. In another form, a single protrusion extends axially from one bearing surface of the interbody device to form a spike or anchoring, rotating protrusion, while the opposite bearing surface may be slightly rounded and/or comprising a bone-ingrowth promoting surface.

Rotational motion is achieved through one or more protrusions incorporated into the spinal interbody device. In one articulating form, a first protrusion extends perpendicularly from the superior aspect of the disc-shaped interbody device to form a spike or rotational protrusion, while a second protrusion extends axially from the inferior aspect of the interbody device to form a second spike or rotational protrusion. Protrusions preferably extend perpendicular from the apex of both the first and second arcuate articulating surfaces.

Abstract: A method of 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, wherein the fibrinogen, the activating compound or both has been reconstituted with a solution containing at least one additive, with the proviso that a corticosteroid is absent from the fibrin sealant injected into the disc.

Abstract: An apparatus for percutaneous delivery of a sealant comprising: at least two fluid reservoirs, an introducer needle having a distal tip that is in fluid communication with at least one reservoir, a fluid delivery tube that is in fluid communication with a second reservoir, wherein the fluid delivery tube has a tip and wherein the fluid delivery tube is configured so that the tip of the fluid delivery tube does not extend past the distal tip of the introducer needle during use.

Abstract: A method of 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 an anesthetic, 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.

Abstract: A method of repairing a defect in an annulus fibrosus of an intervertebral disc, without excising the entire nucleus pulposus of the disc. The method includes inserting an introducer needle through the annulus fibrosus by puncturing the annulus fibrosus with the introducer needle, injecting an in situ curable, bio-compatible polymerizable or polymeric material composition into the disc through the introducer needle directly or indirectly so that the in situ curable composition contacts a defect in the annulus fibrosus; and curing said material in situ.
