Polaris 5.5 Spinal System and Polaris 5.5/Cypher Spinal System, Thoracolumbosacral pedicle screw system
Zimmer Biomet is conducting a medical device correction to update the Instructions for Use (IFU) and the Surgical Techniques for the Polaris Spinal System Translation Screw and Cypher MIS Screw System. Users should be aware that changes were made to the contraindications section indicating that the Translation Screws should not be used with a direct current stimulation, as a high probability of construct failure exists when using Translation Screws containing CoCr with direct current simulation system.
Domestic distribution nationwide. As direct stimulation devices are only available in the US, this contraindication does not apply to international customers.
