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. Similarly configured fusion salvage devices are also described.

Similarly configured fusion salvage devices are also described.

A method and apparatus is provided for use in spinal fusion procedures. An interbody fusion device has a first piece that is a load bearing device designed to bear the axial loading from the end plates of adjacent vertebrae. A second piece of the interbody fusion device is a retention device whose function is to prevent migration of the load bearing device. One or more fasteners secure the retention device to the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion. The second piece can be configured to include lips that abut the apothyseal rings during, with the plate including bores angled such that fasteners penetrate the apothyseal rings.

A composite bone graft which comprises an allograft bone component; a synthetic bone substitute, wherein the synthetic bone substitute is in contact with the allograft bone component. The composite is arranged within a resorbable mesh casing.

A unitary intervertebral device, having no moving components is provided for non-fusion articulation applications. The interbody articulating device allows for limited flexion and rotation between 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 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. In another form, a single protrusion extends axially from the superior aspect of a circular-shape of the interbody device to form a spike or anchoring protrusion, while the inferior surface may be slightly rounded and/or comprising a bone-ingrowth promoting surface. In another form, one or both of the first and/or second arcuate surfaces may be highly polished. Numerous planar geometries are described to define various profiles of the disc replacement implant which may be utilized, including irregular Reuleaux polygons. Numerous variations of the disc replacement and methods of use are described. Similarly configured fusion salvage devices are also described.

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.

A composite bone graft which comprises an allograft bone component; a synthetic bone substitute, wherein the synthetic bone substitute is in contact with the allograft bone component. The composite is arranged in a core/outer layer structure.
