A system and method for repairing an annulus defect in a spinal disc includes at least one block member (50, 150) positionable in or adjacent to the annulus defect. And at least one anchor (70, 80, 170, 180) for securing the block member (50, 150) to adjacent tissue while retracted into the adjacent vertebra. Block members (50, 150) may be used to repair defects and / or nuclear material, one or more implants, biocompatible materials or devices, and / or other disposed in disc space In order to hold the object, it extends over at least part of the ring defect. Instruments are also provided to facilitate pretreatment of the implantation site of the ring repair system. [Selection] Figure 1 |
