The Kidney-Shaped Lumbar Interbody Fusion Cage is manufactured from PEEK (Polyetheretherketone) material with integrated radiopaque tantalum markers to assist intraoperative placement and postoperative imaging.
Its anatomical kidney-shaped profile facilitates precise positioning and optimal fit between the vertebral bodies during lumbar interbody fusion.
The cage functions on the prnciple of distraction-compression stabilization, providing immediate segmental support, resistance to rotational and shear forces, and promoting axial load transfer—creating a biomechanical environment conducive to successful intervertebral fusion.
● Anatomically contoured kidney shape for enhanced in-situ adjustability
● Wedge-shaped endplates to match the vertebral anatomy and maintain sagittal alignment
● Pyramidal serrations on the top and bottom surfaces to resist cage migration
● Large central graft window for packing autograft or synthetic bone substitutes
● Radiopaque tantalum markers inserted in strategic positions for intraoperative and postoperative localization
● Made of PEEK, a biocompatible, radiolucent material with excellent mechanical strength
● Bullet-tip leading edge for smooth and easy insertion
● Kidney-shaped curvature improves in-body positioning and anatomical conformity
● Wedge-shaped surfaces enhance endplate contact and stability
● Pyramidal teeth reduce risk of expulsion post-implantation
● Large graft window increases bone graft volume and enhances fusion potential
● Multiple size options available to accommodate different patient anatomies
● Elastic modulus similar to bone, reducing stress shielding and enhancing osseointegration
● Radiolucency of PEEK material allows for post-op imaging, while tantalum markers ensure visibility
