Abstract
A surgical method of repair and reconstruction of the spinal disc wall, or annulus fibrosus, after surgical incision or pathologic rupture, through the insertion of a collapsible patch through an aperture into the subannular space and causing or allowing the patch to expand into an expanded configuration to bridge the aperture. The technique thereby occludes the aperture from the interior of the vertebral disc and prevents the migration of nucleus pulposus therethrough.
