The Concero Facet Screw System is a minimally invasive fixation alternative to pedicle screws, intended to stabilize the spine during fusion procedures at single or multiple levels from L1 to S1 through bilateral immobilization of the facet joints. It is available in multiple lengths and diameters and in both cannulated and non-cannulated versions with customized instrumentation. The system also features a toothed washer for improved bone fixation and a lag screw design for secure compression, eliminating the need for external compression mechanisms.
