TDX Posterior Dynamic Stabilization is a posterior dynamic rod allowing natural movements in the treated segments of the lumbar spine. Together with the company’s SFS pedicle screws, also available with a hydroxyapatite (HA) coating to optimize bone fixation, the rods can be used for single level motion preservation treatment, or as an adjunct to fusion. The TDX Stabilization System is intended to provide posterior stabilization while allowing small degrees of natural movement of the lumbar spine. As a single level treatment, the TDX rods enable movements in flexion, extension, lateral bending and rotation. Used as an adjunct to fusion, the TDX rods render dynamic stabilization while providing traditional rigid fixation in adjacent levels.
Benefits:
- Implantation through known SFS surgical technique
- Can be used in conjunction with rigid fixation
- Pre-assembled for reduced insertion time
- As a single level treatment allows for natural movement of the lumbar spine
- Precision instruments with ergonomic handles improve tactile feel
- Hydroxyapatite (HA) coated screws that facilitate bony ingrowth and improve stability of construct
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.
