The MANTIS (minimal access non-traumatic insertion system) allows cannulated pedicle screws to be placed appropriately in a true percutaneous fashion. This system is designed to address up to three level procedures for both degenerative and deformity applications. Precise rod contouring above the skin before rod insertion enhances the screw and rod construct. The cannulated screw design is based on the trusted Xia Pedicle Screw system and uses the same buttress thread closure mechanism.
