Stabilimax Dynamic Spine Stabilization System, a device designed to provide stabilization while allowing for motion. Rachiotek LLC, a recently formed Delaware company, has acquired the assets of Applied Spine Technologies.
The Stabilimax NZ is inserted through pedicle screws similar to those used for posterior lumbar fusion. The device is then attached to the screws. The Stabilimax NZ is comprised of a dual spring mechanism. The inner spring works in spinal extension and the outer spring works in spinal flexion. The springs counter-oppose one another in lateral bending.The spring mechanism is paired with a ball-and-socket which works in axial rotation (twisting) of the spine. All in all lending to maintained motion similar to that of a healthy spine.
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.
About Rachiotek
Rachiotek LLC, headquartered in Wellesley, MA, is developing the Stabilimax™ Dynamic Spine Stabilization System, a posterior dynamic stabilization device designed to support an injured or degenerated spine without eliminating motion. Stabilimax is expected to offer numerous advantages over current spinal fixation products including a less invasive and less traumatic procedure, maintenance of kinematic spine motion and disc function, as well as the potential to prevent or reduce the incidence of adjacent segment disc disease.http://rachiotek.com
