B-Dyn™ is a posterior dynamic motion preservation system which is designed for application from thoracic vertebrae T10 to sacrum S1.The dynamic rod B-Dyn™ is composed of a silicone cushion, that helps to decrease intradiscal pressure and to relieve facet loads, and an elastomere ring that controls hyper mobility and limits extention of the spine segment.
B-Dyn™ enables all anatomical motion such as flexion/extension, axial rotation as well as lateral bending.Beside a one level motion preservation device, B-Dyn™ has also a version with a longer fusion rod to combine 1 or 2 levels of fusion with motion preservation for the adjacent segment.The B-Dyn™ is manufactured and sold by Cousin Surgery, international leader in implants for visceral and spinal surgery, Cousin Surgery is an industrial group with expertise in implantable textiles: a very rare skill, inherited from a history entirely devoted to textiles and innovation.
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.
