AnnexTM Adjacent Level System consists of a selection of non-sterile, single use connectors manufactured from titanium alloy and cobalt chrome alloy, for attachment to an existing 5.5mm diameter rod construct to extend a rigid spinal construct. The connectors are provided in a variety of sizes and shapes to accommodate variations in anatomy and spacing/positioning of existing screw and rod hardware.
When used with pedicle screw fixation systems of the noncervical spine in skeletally mature patients, the AnneXTM Adjacent Level System is indicated for degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudoarthrosis).
The AnnexTM Adjacent Level System can be linked to 5.5mm diameter rod systems, including the CapSure® or Sniper®R Spine Systems.Annex® Adjacent Level 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.
About Spine Wave
Spine Wave was founded in February 2001 by former Sofamor Danek executives Mark LoGuidice and John Pafford. Since then, the Company has grown by delivering meaningful solutions to real clinical challenges. As a result, Spine Wave has become the innovation leader in expandable and less-invasive spinal technologies with a broad and differentiated product and intellectual property portfolio.Today, the Company continues that tradition of focused development and commercialization of clinical solutions for large fast-growing spinal market segments.http://www.spinewave.com
