The pedicle screw systems with semirigid rods have not received approval from the U.S. Food and Drug Administration (FDA) for use other than as an adjunct to spinal fusion. The FDA has specified that separate approval is required for “off-label” marketing of these devices.But the growing number of older people with age-related degenerative disorders of the spine will continue to play a large part in driving the demand for spinal fusion and posterior dynamic stabilization procedures.
These devices can be used to prevent adjacent-segment disease, either by replacing the whole construct with dynamic rods or by “topping off” the rigid instrumented segment with pedicle-based dynamic devices, avoiding an abrupt change from a rigid construct to the more mobile adjacent segment. It has also been argued that using pedicle-based dynamic devices can promote better fusion because of micromovements across endplates, and can protect from implant failure because of better load sharing through the implant. Finally, these devices can be used to stabilize posterior iatrogenic destabilizing surgery, such as wide laminectomy and facetectomy.
