Kangli Orthopaedics offers this titanium alloy posterior cervical screw-rod fixation system for assembling posterior cervical and occipital constructs. Paired curved rods provide the longitudinal framework, while rod-mounted screw interfaces connect selected fixation points to the construct. Modular transverse and upper-end components support different cervical, occipital, and laminar anchoring configurations.
Paired Rods for Posterior Cervical Constructs
The system includes two long, cylindrical rods with gentle curves that create separate longitudinal paths through the construct. Their curved profiles direct the upper ends toward the connecting hardware and accommodate the geometry of posterior cervical and occipital assemblies.
Screw-to-Rod Interfaces for Segmental Assembly
Threaded screw shafts end in heads that seat against the rods through clamp bodies. This direct interface links each selected screw location to the rod framework, allowing multiple fixation points to be incorporated into one screw-and-rod construct without using a separate plate at every location.
Cervical Crosslink for Transverse Connection
The Cervical Crosslink spans the space between the paired rods at a selected transverse position. It joins the parallel rods into one connected assembly during posterior cervical construct preparation.
Occipital and Laminar Connection Options
The Occipital Bone Rod serves as the upper rod member when the construct extends toward the occipital region. The Laminar Hook provides a hook-shaped connection at the lamina, giving distributors and orthopedic professionals an additional component option for posterior laminar anchoring within the same rod-based layout.
