Lumbar Interbody Fusion Cage LF-I

The lumbar interbody fusion cage is made of PEEK material with radiopaque markers composed of pure tantalum. 

It is available in various sizes with different lengths, widths, and heights.

The cage is inserted between two vertebral bodies and functions based on the principle of distraction–compression stabilization. 

Through the force and counterforce generated by distraction and compression, the cage achieves anti-rotation and anti-shear effects while transmitting axial load. 

This provides immediate and early segmental stability and creates a favorable biomechanical environment for interbody fusion, leading to permanent interface integration.

● Anatomically contoured upper and lower surfaces fit the vertebral endplates.

● Serrated top and bottom surfaces prevent migration from the intervertebral space.

● A central bone graft window allows filling with grafting materials such as autogenous cancellous bone or synthetic bone substitutes.

● As PEEK is radiolucent, metallic radiopaque markers are embedded in specific positions to facilitate intraoperative and postoperative visualization.

● Bullet-shaped anterior design for easier insertion.

● Convex anatomical surfaces provide a self-distracting effect and better endplate contact.

● Serrated surfaces prevent implant migration.

● Large bone graft window enhances fusion rate.

● Wide range of sizes to meet diverse clinical needs.

● PEEK material has an elastic modulus close to that of bone, reducing stress shielding and promoting osseointegration.

● Radiolucent properties with tantalum markers enable accurate intraoperative and postoperative positioning.
