AviatorTM Biomechanical Review Anterior Cervical Plating System System Overview The Aviator™ anterior cervical plating Instrumentation options further system offers a unique double screw enhance surgical technique versatility by locking mechanism, a high degree of matching surgeon preference regarding screw angulation and simplified approach and screw pathway instrumentation. preparation. The primary screw locking mechanism is The Aviator™ plate is made of Titanium a spring-loaded bar, which is designed to Alloy (Ti-6Al-4V) and is 2.5mm thick automatically lock over the screw heads. and 17.4mm wide. Rotation of the blocker locks the spring bar in place and allows for additional The lordotic curve, or radius of visual and tactile feedback that the curvature, in the sagittal plane is 190mm screws are locked. for one- and two-level plates, and 390mm for three- and four-level plates. This system provides variable angle The plate also features 25mm of screws that offer 20° of screw angulation curvature in the axial plane for matching and allow semi-constrained bone screw of the patient’s anatomy.
