The self-stabilizing cervical fusion cage is an intervertebral spacer made of radiolucent PEEK (polyether–ether ketone) with integrated pure-tantalum X ray markers.
It is inserted between two cervical vertebrae and secured with titanium-alloy screws, restoring disc height and normal cervical lordosis. The cage’s unique design uses a distraction–compression stabilization mechanism (originally described by Bagby) to achieve immediate segmental stability: by distracting the disc space and then locking the implant, opposing forces are generated that resist rotation and shear, providing early fixation to aid fusion.
In practice, the cage reconstructs the anterior spinal column after discectomy, bears axial loads in place of the removed disc, and maintains tension in the annulus and ligamentous structures. While it provides instant stability, ultimate fusion depends on bony ingrowth through and around the implant.
Easy to use
● Quick nailing easy fastening
● Lockingis achieved with the insertion of 2 screws.
● The positioning pin rotates 90° clockwise to effectively preventscrew loosening.
Diverse tool designs
● Universal prosthesis holder (standard configuration), Effectively prevents tools from obstructing the surgical view.
Designed based on human anatomical dimensions
● Reduces the need for uncinate process resecion, providing astable environment for intervertebral fusion and lowering the risk of epiduralvenous plexus bleeding, dural tears,and nerve root iniury caused by related procedures.
Quick nailing easy fastening
● No need to reserve extra space for instrument manipulation, allowing forsmallerskin cuts.
● Perfectly compatible with the concept ofsmall incisions and precise operationsunder a microscope or spinal endoscope.
