Abstract:
A vertebral disc tensioning device that restores the loss of disc height as a result of disc degeneration and other factors. The device includes first and second pedicle screws each including a screw body portion and a ball head. The device also includes first and second screw head portions each including an internal threaded bore where the first screw is inserted in the first screw head portion and is pivotally mounted relative thereto and the second screw is inserted in the second screw head portion and is pivotally mounted thereto. The device also includes a rigid connector that couples the first and second screw head portions where bolts are threaded through the connector and into the internal threaded bores of the first and second screw head portions. The device also includes a spring assembly offset from the rigid connector that applies a bias to separate the pedicle screws.
