Expedium and Viper Peek Rod (Evolved from the Expedium and Viper 2 Spine Systems), provides Spine Surgeons with the latest advancements in thoracolumbar fusion fixation technologies. The Expedium Peek Rod is an integral extension of the Expedium 5.5 Spine Systems that supports uncompromising versatility for both open and percutaneous posterior approaches. Incorporating the latest in load sharing designs, the Expedium Peek Rod System represents the next generation of fusion procedure solutions.
Features:
Load Sharing Design
- PEEK rod constructs shift compressive axial forces from the posterior elements to the interbody fusion site, more closely reproducing the normal loading characteristics of the lumbar spine compared to Titanium rod constructs
- PEEK features a lower modulus of elasticity compared to Titanium and more closely mimics the material characteristics of cancellous or cortical bone
Imaging Compatability
- PEEK-OPTIMA® image contrast compounds incorporate Barium Sulfate (BaSO4), a radiopaque material that achieves the optimal balance of implant and fusion mass visualisation, with reduced artifacts or scatter that is traditionally associated with Titanium rods
- The entire rod can be visualised using standard fluoroscopy
Tantalum Markers support visualisation of rod end positions relative to the pedicle screw heads
System Versatility
- Compatible with ExpediumTM 5.5 and ViperTM 2 Spine Systems for complete interoperative flexibility and support of both open and percutaneous MIS approaches
- Flat bottom set screw closure mechanism eliminates the need to use special pedicle screws or instrumentation sets helping to maximise operating room efficiency PEEK-OPTIMA® is a Registered Trademark of Invibio Inc.
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.
