Method of treating spinal internal disk derangement
A method of treating a spinal disk according to the present invention can include inserting an alloplastic bulking agent into the spinal disk to treat the defect. The alloplastic bulking agent has a plurality of microparticles. The bulking agent results in at least one of sealing the defect, increasing a pressure of the disk, increasing a height of the disk, improving stability of the disk and improving structural integrity of the disk.
1. A method of sealing an annular tear or fissure in an annulus fibrosis during a discography procedure comprising:
performing a discography procedure on a spinal disk;
detecting the annular tear or fissure in the discography procedure;
after the detecting, delivering a biocompatible agent to an interior portion of the spinal disk inside the annulus fibrosis into or proximate the annular tear or fissure such that the biocompatible agent seals the annular tear or fissure;
after the delivering, incorporating the biocompatible agent into host tissue through formation of permanent tissue proximate the biocompatible agent;
wherein the biocompatible agent comprises a plurality of microparticles, the microparticles each having a diameter in the range of 5 to 500 microns.
2. The method of claim 1 , further comprising at least one of increasing a pressure of the disk, increasing a height of the disk, improving stability of the disk and improving structural integrity of the disk.
3. The method of claim 1 , wherein the agent comprises at least one of water, saline, a tenside, radiopaque dye, and a chromophobe.
4. The method of claim 1 , wherein said microparticles comprise one or more of poly methacrylate, polymethylmethacrylate (PMMA), a cured polymer, a fully polymerized polymer, and glass.
5. The method of claim 1 , wherein delivering the agent comprises viewing the spinal disk through a scope.
6. The method of claim 1 , wherein delivering the agent comprises delivering 0.5 to 1.5 cubic centimeters of the agent.
7. The method of claim 1 , wherein delivering the agent comprises delivering the agent to a nucleus pulposus of the disk.
