Inertia® Pedicle Screw System

The INERTIA® Pedicle Screw System is a top-loading comprehensive system intended to address numerous pathologies for the thoracic and lumbar spine. INERTIA pedicle screws are designed with a double-lead thread pattern allowing surgeons to advance the screws twice as fast as standard screws. A unique single-step screw closure mechanism minimizes the chances of cross-threading and significantly reduces head splaying. The system also features a "Rod Capture Mechanism" for retention of the rod within the screw head, generous polyaxial screw angulation and a low profile design.
