1. A method of reconstructing and augmenting a vertebral endplate surface, comprising:

  • identifying a vertebral body having an outer surface and a vertebral endplate surface adjacent a damaged tissue;

    driving first and second anchors into the outer surface of said vertebral body and along and across a cupped cortical rim of said vertebral endplate surface adjacent said damaged tissue;

    wherein each of said first and second anchors comprises an upper neck and a lower bone engagement portion;

    positioning the lower bone engagement portion below said vertebral endplate surface adjacent said damaged tissue;

    recessing the lower bone engagement portion within the outer surface of the vertebral body;

    inserting augmentation material along said vertebral endplate surface adjacent said damaged tissue;

    wherein the augmentation material comprises a proximal portion and a distal portion;

    coupling an attachment site of said upper neck of said first anchor to the proximal portion of the augmentation material; and

    coupling an attachment site of said upper neck of said second anchor to the distal portion of the augmentation material, thereby reconstructing and augmenting said vertebral endplate.
