Abstract:
1. A method of reducing implant migration within a spine comprising: identifying a defect in an anulus of the intervertebral disc, selecting an implantation site within a spine, wherein said spine has a first spinal region and a second spinal region, providing an implant, wherein said implant has a first implant region and a second implant region, inserting the implant through and entirely beyond the defect and into the space occupied by the nucleus pulposus, wherein the insertion of the implant is performed without removing any portion of the intervertebral disc so as not to cause disc height loss; implanting said first implant region in the first spinal region; and implanting said second implant region in the second spinal region, thereby reducing migration of the implant within the spine.
