Posterior Cervical Screw-Rod Fixation System Introduction
The Cervical Posterior Screw-Rod Fixation System is designed for posterior fixation procedures involving the cervical spine. Its system concept combines screws and connecting components to support configuration planning across different surgical requirements.
Posterior Cervical Screw-Rod Fixation System Key Features and Advantages
Anatomical Occipito-Cervical Contour
A pre-bent 135° design at the occipito-cervical junction is intended to follow the anatomy of this transition area and support construct planning.
Polyaxial Screw Design
The screw design allows up to 55° of unidirectional angulation, offering flexibility when planning screw and rod alignment.
Negative-Angle Thread Design
The thread design is intended to help resist screw-arm expansion, a useful design consideration when evaluating fixation components.
Plate-Clamp Cross-Link Option
A plate-clamp cross-link is designed to facilitate connection when screws are not arranged in a straight line.
Focused Cervical Product Offering
The system gives distributors a dedicated cervical posterior fixation option to assess alongside other cervical and spine products in their portfolio.
