CD HORIZON PEEK RODS System uses rods made of polyetheretherketone, a semi-crystalline thermoplastic polymer that meets all biocompatibility requirements and has a long history of use in surgical implants. When combined with CD HORIZON® Spinal System-based pedicle screws and minimally invasive approach options such as the MAST QUADRANT™ Retractor Set, the CD HORIZON LEGACY PEEK Rod dynamically stabilizes the affected segment while allowing for a streamlined surgical technique that preserves much of the natural anatomy.
The CD HORIZON LEGACY PEEK Rod is suited for stabilizing the spine following interbody structural graft support. This “tension band”approach is based on Wolff’s Law that bone forms where it is needed.
Some of the benefits of this include:
- Reduced stress on the screw-bone anchor points and construct instrumentation
- Better stress distribution throughout the construct potentially resulting in reduced risk of construct failure
- PEEK material is radiolucent reducing scatter and artifact in images allowing for better patient follow-up, especially within fusion assessment through CT / MRI
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.
