Cervical Interbody Fusion Cage (Insert-type)

● Immediate Fixation and Stability: Self-locking titanium clips drive vertically into the adjacent vertebrae, clamping the cage in place. This rigid anchoring resists rotational and shear forces and provides instant postoperative stability.

● Large Graft Volume: The insertable spacer is hollow with ample internal space, accommodating substantial bone graft material to promote fusion.

● Zero-Profile (Intra-Discal) Design: The cage sits entirely within the intervertebral space, eliminating any overhang. This intra-discal “zero-notch” profile (no need for an anterior plate) minimizes soft-tissue irritation and reduces the risk of dysphagia or adjacent-segment ossification.

● Textured Endplates: Serrated/wave-like teeth on the implant surfaces enhance initial fixation by gripping the endplates, further preventing migration.

● Radiopaque Positioning: Integrated pure tantalum marker pins make the device fully visible on X-ray, while the PEEK body remains radiolucent. This allows surgeons to verify implant placement intraoperatively and to monitor fusion progress clearly on postoperative CT/MRI.

● Bone-Compatible Elasticity: Constructed of PEEK (polyetheretherketone), the cage has an elastic modulus close to bone. Its elastic cushioning promotes uniform bone apposition and reduces stress shielding at the bone-implant interface.

● High Fatigue Strength: The materials are fatigue-tested for long-term load-bearing. The design supports sustained axial loads without implant failure, ensuring durability until solid bony fusion occurs.

● Minimally Invasive Insertion: The Uni-C cage has a slim leading edge for easy insertion through a small anterior approach. Dedicated instruments allow precise millimeter-scale depth adjustment, increasing insertion accuracy and safety.

● Flexible Sizing: Available in multiple footprints and heights (10 size options), the system lets surgeons choose the optimal cage dimensions for each patient’s anatomy.

● Reduced Dysphagia Risk: Since the entire implant fits within the disc space and no external plate is required, there is minimal anterior hardware protrusion. This design significantly lowers postoperative swallowing difficulties.

● Avoids Anatomical Obstacles: Clips are driven vertically from above and below, avoiding interference from the jaw or clavicle even at high or low cervical levels.

● Imaging Compatibility: The PEEK body causes no MRI artifacts, and the radiopaque markers ensure the implant can be tracked on all imaging modalities.

● Stress-Shielding Reduction: The PEEK cage’s bone-like modulus and internal graft volume encourage fusion. This has been shown to improve bony integration compared to rigid metal implants.

● Long-Term Stability: The combination of robust materials (PEEK and Ti-alloy) and self-locking clips provides durable fixation during the entire fusion period.
