NuVasive Launches SpheRx DBR Fixation System

NuVasive, a medical device company focused on developing products for minimally disruptive surgical treatments for the spine, has launched its SpheRx Dual Ball Rod (DBR) Minimally Disruptive Fixation System for percutaneous posterior spinal fixation.

SpheRx DBR's product design allows for a simple, constrained rod insertion achieved through a dual ball rod with spherical ends, which are geometrically constrained within the DBR Guides during rod insertion, guiding the rod directly and easily into the heads of the pedicle screws. The spherical ends of the rod fit securely within the screws at both ends of the construct with no rod overhang, reducing the incidence of superior facet joint violation and tissue trauma.

The SpheRx DBR system is able to perform "instrument-free" compression. Instrument-free compression allows the spine surgeon to easily apply up to 5 mm of compression by simply moving the DBR guides with his or her hands. SpheRx DBR is also designed to be seamlessly integrated with the company's NeuroVision Nerve Avoidance System.
