DYNABOLT: In August 27, 2010 Exactech, Inc. a developer and producer of bone and joint restoration products for hip, knee, shoulder, spine and biologic materials, announced the acquisition of several innovative spine product lines and all related technology from VertiFlex, Inc. a leading developer of minimally invasive and motion preserving spinal surgery technologies. Included in the acquisition are the Silverbolt Percutaneous Pedicle Screw System and related assets.Last February 1, 2017 ChoiceSpine announced it has acquired the spinal assets of Exactech.
Features:
- Dynabolt® is an alternative rod option that can be used with the Silverbolt MIS System.* It provides load sharing, while reducing intradiscal pressure of the adjacent levels by providing:
- Five degrees of angular movement in the mid-sagittal plane, allowing for flexion and extension
- Five degrees of angular movement in the coronal plane, allowing for lateral bending 1mm of compression
Benefits:
- Controlled Dynamism: Provides controlled motion as an alternative to rigid stabilization
- Percutaneous delivery with Silverbolt™ MIS Screw System
- Designed to preserve anatomical motion to reduce the potential for adjacent segmental degeneration
- Can be easily delivered minimally invasive or by utilizing traditional surgical techniques
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.
