Weigao China’s largest manufacturer of implants and related surgical instruments for traumatology and spine surgery, offers a spinal stabilisation system called “Tulip”, which uses semi-rigid rods made from PEEK-OPTIMA® to bridge the gap between rigid and dynamic systems. The system is indicated when one to three levels of the spine, including the lumbosacral region, require posterior pedicle-screw fixation or when fusion surgery is required for a segment of the spine where degenerative disc disease is present.
Features:
- Two types of the domestic manufactured rods are available: a 6.35mm-diameter round rod, and a 6.35×7.2mm-diameter oval rod.
- PEEK-OPTIMA polymer-based spinal rod components are bridging the treatment gap between rigid and dynamic systems. According to research results presented in Europe the rods are strong enough to restore lumbar spine stability and have much lower failure rates than titanium.1) Spinal rods made from the biocompatible polymer offer numerous advantages, including improved load sharing to encourage fusion,2-4) more physiologic loading at adjacent levels, which may decelerate degeneration 5-6) and reduced stress at the bone-to-screw interface, which may prevent screw pull-out, especially in patients with questionable bone quality.5-6) This improved load sharing, plus clear, artefact-free imaging for easy device placement and monitoring, are important advantages that PEEK-OPTIMA provides over metal rods.
About Pedicle Screw/Rod–Based Dynamic Stabilization Devices
Dynamic stabilization is a surgical technique designed to allow for some movement of the spine, while maintaining enough stability to prevent too much movement. Pedicle-based dynamic devices were first designed to stabilize the abnormal segment and to unload degenerated discs and facet joints, while maintaining the same level of normal motion.By unloading the pressure on the degenerated disc and facets, pedicle-based dynamic devices have the potential to reduce pain associated with these anatomical structures. Furthermore, 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.
