Abstract

A vertebral disc annular fibrosis tensioning and lengthening device that restores the loss of disc height as a result of disc degeneration and other factors. The vertebral disc annular fibrosis tensioning and lengthening device includes pedicle screws having heads with cup-shaped cavities. The pedicle screws are threaded into the vertebral bodies of adjacent vertebrae through the pedicles so that open parts of the heads of the pedicle screws face each other. A spring is inserted into the cup-shaped cavities in compression so that the spring bias forces the pedicle screws apart, thus increasing the height of the disc space.
