The Oblique Lateral Interbody Fusion (OLIF) Cage is made of radiolucent PEEK (Polyetheretherketone) and embedded with radiopaque tantalum markers to enable precise intraoperative and postoperative positioning.
It is designed to be implanted between lumbar vertebral bodies via the oblique lateral approach, which allows access through a natural anatomical corridor, minimizing muscle and nerve disruption.
The cage applies the principle of distraction-compression stabilization, providing immediate segmental stability, resistance to rotation and shear, and an optimal environment for long-term intervertebral fusion.
● Anatomical wedge-shaped or parallel endplates to match vertebral endplate morphology
● Anti-migration serrated surfaces on the top and bottom to prevent cage dislodgement
● Central graft window for filling with autologous bone or bone substitutes
● Beveled bullet-shaped leading edge for smooth insertion through the oblique corridor
● Variety of shapes and sizes including cylindrical or rectangular profiles with angled tips
● Radiopaque tantalum markers allow for clear identification and positioning under fluoroscopy or X-ray
● Made from PEEK, which provides excellent imaging compatibility and mechanical strength
● Minimally invasive approach compatibility, reducing tissue trauma and accelerating recovery
● Bullet-nose design facilitates insertion with minimal disruption
● Customized wedge/flat surfaces ensure optimal fit with various vertebral anatomies
● Large bone graft window improves fusion rates
● Multiple sizes available to meet a wide range of clinical and anatomical requirements
● Elastic modulus of PEEK is similar to bone, reducing stress shielding and promoting osteointegration
● Radiographic markers ensure precise intraoperative placement and postoperative monitoring
