| STALIF C® |
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.
Benefits:
Efficient Design:Fewer, Simpler Surgical Steps
- STALIF C® was designed to simplify surgery and reduce the number of surgical steps required.
- No Supplemental FixationSTALIF C’s integrated cage and screw system is cleared for use withoutsupplemental fixation. Some surgeons, however, may still choose to use anterior plates or posterior fixation.
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 fusion2.2 Thalgott J, MD; Malone M – Principles of Interbody Fixation, White Paper, Centinel Spine Journal, Number 1 2009
Horizontal Inclination:Midline Convergence
- Horizontal InclinationSTALIF 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
