Abstract
Apparatus and methods aid the annulus in controlling vertebral motion, thereby preventing additional annular tears, and decreasing pain from annular tears. A biocompatible fabric or mesh is attached to the annulus. The material may be attached to the inside and/or outside of the annulus by stitches, staples, adhesives, or other suitable techniques. Alternatively, the fabric may be attached to the vertebra above and below the disc by screws, staples, tacks, or porous material for bone ingrowth such as titanium.
