This system offers a unique double screw locking mechanism, a high degree of screw angulation and simplified instrumentation. The primary screw locking mechanism is a spring-loaded bar, which is designed to automatically lock over the screw heads. Rotation of the blocker then locks the spring bar in place and allows for additional visual and tactile feedback that the screws are locked. The system features both fixed and variable angle screws to accommodate both rigid and semi-constrained bone screw fixation philosophies.
