COSMIC™posterior dynamic system (Ulrich GmbH &Co. KG, Ulm, Germany) uses hinged pedicle heads to allow for segmental motion. Cosmic™ is an implant system for operative posterior stabilization and fixation of the human thoracic, lumbar and sacral spine in case of degenerative spine diseases.
With degenerative spine diseases without significant substance defects of the anterior column and without the necessity for correction, it is also possible to apply the non-fusion technique.With long stabilizations, the stress inside the section of the instrumentation increases. Therefore the instrumentation is limited to three segments for the non-fusion technique. If longer instrumentations are necessary, some of the segments will have to be fused.
Features :
- Posterior stabilization of the thoracic to sacral spine
- Rod-screw system for the dynamic stabilization without fusion
- Pedicle screws are available in diameter 6.0 and 7.0 mm
- Monoaxial mobility of the screw with hinged joint
- Bonit® coating
- CosmicMIA™dynamic minimally invasive system
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.
