The Posterior Occipital-Cervical-Thoracic Spinal System is designed for posterior spinal fixation and fusion from the occiput to the thoracic spine.The system consists of polyaxial screws, titanium rods (standard, dual-diameter, and adjustable types), crosslinks, lateral connectors, axial and domino connectors, occipital screws, occipital plates (standard and arched), lamina hooks, and locking set screws.
Through a posterior surgical approach, polyaxial screws are inserted into the vertebral pedicles, and pre-contoured or adjustable titanium rods are fixed using set screws. The system forms a three-dimensional load-sharing construct, offering strong biomechanical stability for realignment and fusion of the occipital-cervical-thoracic segments.
All components are made from TC4 titanium alloy.
Comprehensive Posterior Fixation: Supports decompression, reduction, internal fixation, and fusion across the occipital, cervical, and thoracic spine.
Polyaxial Screws: Provide strong axial pullout, bending, and rotational resistance. Available in various types: Fully threaded, partially threaded, hollow fully threaded, hollow partially threaded, and standard polyaxial screws, meeting the needs of different spinal levels and pathologies.
Rod Options:
● Standard rods for cervical fixation;
● Dual-diameter rods for cervical-to-thoracic extension, ensuring stiffness and low-profile fusion;
● Adjustable rods with hinged joints to accommodate occipito-cervical angles outside the body, simplifying surgery and reducing in-situ rod contouring.
Occipital Fixation:
● Y-shaped occipital plate for midline screw insertion;
● Arched occipital plate with multiple screw holes for flexible anchorage and enhanced stability.
Multi-axial Coupling: Screws can reach up to 60° conical angulation; rod saddles allow up to 45° angulation per side for greater intraoperative flexibility.
Spherical Base Locking Screws: Provide secure rod fixation by compressing against the rod to resist axial and rotational displacement.
Modular System Accessories: Includes crosslinks, domino connectors, lamina hooks, and lateral connectors for customizable constructs and enhanced construct integrity.
● Versatile Coverage: Supports fixation from occiput to upper thoracic spine.
● Multiple Fixation Methods: Offers three occipital fixation options and two types of occipito-cervical rods.
● Wide Range of Screw Types: Available in solid and cannulated, full or partial threads, allowing up to 60° angular range.
● Comprehensive Accessory Set: Includes crosslinks, domino connectors, lamina hooks, and lateral connectors to accommodate various surgical needs.
● Strong Biomechanical Performance: Tri-column stabilization, improved sagittal and coronal control, and enhanced fusion environment.
● Simplified Surgical Workflow: Adjustable rods reduce intraoperative rod bending and shorten operation time.
