* The device system is designed for use with autograft bone and/or allogeneic bone graft composed of cancellous and/or corticocancellous bone graft, to facilitate fusion. Multilevel indicates for 1-2 contiguous levels.
No-Profile® Anterior Cervical Integrated Interbody System


STALIF C® is part of an “integrated” system of implants and instruments designed to create consistent clinical results and avoid more destructive multiple incision surgeries.

Fewer, Simpler Surgical Steps


STALIF C® was designed to simplify surgery and reduce the number of surgical steps required.

No Supplemental Fixation

STALIF C's integrated cage and screw system is cleared for use without supplemental fixation. Some surgeons, however, may still choose to use anterior plates or posterior fixation.

3 Screw Construct

STALIF C screws are 4.0mm in diameter and include our ABO™ (Anti Back-Out™) feature. Our three screw construct is proven to be biomechanically equivalent to a cage and plate.1

Ease of Implantation

Through the co-functioning and coordination of our device and instruments, implantation is significantly eased.

The Lag Effect

Lag screws reduce the vertebral bodies onto the PEEK Cage creating graft / endplate surface compression to provide the best opportunity for fusion.

No-Profile®.
Conforms to Patient Anatomy


The STALIF C® "No-Profile" design allows it to nest fully within the confines of the vertebral body, leaving the anatomy unchanged external to the interbody.

The Lag Effect.
Compressive Fixation Ensures Graft and Endplate Contact


As the preferred design to ensure fixation in cancellous vertebral bone, cancellous screws—combined with our screw head design—produce a lag effect between the vertebral body and the implanted device.

The lag effect provides constant compressive forces against the implant which results in a greater interface between the graft and the endplate to facilitate the fusion process.

Optimal Screw Trajectories.
Engineered to Maximize Opportunities for Fusion


The STALIF C® 3-screw design utilizes a midline convergence pattern in conjunction with an optimal horizontal inclination. These integrated elements conform to AO principles of fracture fixation, increasing the possibility of a fusion2.

Horizontal Inclination

STALIF C® screws are angled and biomechanically designed to direct axial forces along the long axis of the screws—significantly reducing bending moments and preventing de-rotation of the screw and / or screw back- out.

Midline Convergence

Centinel’s converging screw design and angles are biomechanically more resistant to screw backout compared to parallel screws.3 Additionally, midline convergence angles are designed to provide a more secure interbody construct.

Without a doubt I would recommend the surgery that I had because I have my life back.
