A method for providing vertebral disc annular fibrosis tensioning and lengthening that restores the loss of disc height and provides disc regeneration. In one non-limiting embodiment, the method includes inserting pedicle screws into the vertebral bodies of adjacent vertebra and positioning a spring in compression between and in contact with the pedicle screws so that the spring bias forces the pedicle screws apart to provide a distractive force that increases the height of the disc space and promotes the disc regeneration.
