The Concero Facet Screw System is intended to stabilize the spine as an aid to fusion through bilateral immobilization of the facet joints. The Concero facet screws may be used with or without bone graft at single or multiple levels, from C2 to S1 for 3.5 mm and 4.0 mm screws and from L1 to S1 for 4.5 mm screws. The low profile 4.5 mm diameter lag screw comes with both cannulated and non-cannulated options.
When used in conjunction with the Aspen™ Spinous Process Fixation System, the Concero facet screw plus the Aspen device offers a stable, minimally invasive hybrid construct. Bilateral Concero facet screw coupled with the Aspen implant provided overall stability that was equivalent to bilateral pedicle screw
