| Zero-Profile |
Zero-profile anterior cervical interbody fusion device combining the functionality of an interbody spacer and the stability of an anterior plate.
Benefits:
Reduces risk of dysphagia
The implant is contained within the excised disc space anddoes not protrude past the anterior wall of the vertebral body as do anterior cervical plates. This zero anterior profile may be beneficial in reducing the occurrence and severity of postoperative dysphagia1, 2, 3,4. In addition, preparation of the anterior surface of the vertebral body is minimized because the implant does not lie against this surface.
Prevents adjacent level ossification
It has been shown that cervical plates placed near adjacent level discs can contribute to bone formation near or around the adjacent level which may lead to future complications5. Zero-P minimizes this risk, as it remains as far as possible from the adjacent level disc spaces.

Ease of use
Because plate and spacer are preassembled, the plate is automatically aligned upon implant insertion. This avoids the process of aligning and realigning an anterior cervical plate.
The Zero-P screws have a one-step locking conical head which locks the screw to the plate by simply inserting and tightening the screw.

Features:
PEEK interbody spacer
− Radiopaque marker for posterior visualization during imaging
− Spacer component is made of pure medical grade PEEK Optima® (Polyetheretherketone)
− PEEK Optima does not contain carbon fibers reducing the risk of systematic uptake and local connective tissue formation
− Teeth on the implant surface provide initial stability Titanium alloy plate
− Provides a secure, rigid screw locking interface
− Stresses in plate are decoupled from spacer through an innovative interface
Locking head screws
− Screws form a bone wedge with a 40º±5º cranial/caudal angle and 2.5º medial/lateral angle
− One-step locking screws
− Self-tapping screws improve thread purchase
− Trilobular thread cutting flutes are self-centering
