SALUS Dynamic PEEK Rod

SALUS is a Dynamic PEEK Rod with the following features:

• Provides semi-rigid fixation to bridge the gap between rigid and dynamic spinal constructs
• Uses rods made of polyetheretherketone, a semi-crystalline thermoplastic polymer that meets all biocompatibility requirements
• Dynamically stabilizes the affected segment while allowing for a streamlined surgical technique that preserves much of the natural anatomy
• The PEEK Rod material is radiolucent, reducing scatter and artifact in CT and MRI images
• Allows better stress distribution throughout the construct

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.
