The PrimaLOK SP and FF platforms include a polyaxial
interspinous process device and percutaneous facet screw system designed for MIS applications in treatment of lumbar spinal disorders.
This clearance expands the indication for polyaxial
screw placement to include the cervical spine, and also includes clearance for a dual diameter transition rod.
Screws (non-cannulated, cannulated and reduction) for MIS, Mini-Open and Open cases in 30mm-100mm lengths, while maintaining all of the same instrument compatibilities to the implant.
