The Zero-P VA implant is a stand-alone implant for use in cervical interbody fusion 1– 6, which combines the functionality of a cervical interbody spacer and benefits of an anterior cervical plate.
Zero-profile midline
Designed to minimize the risk of contacting local anatomical structures
The Zero-P VA implant does not extend beyond the confines of the intervertebral space midline, limiting risk of contact with vessels and adjacent soft tissues.
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 complications7 .
Zero-P minimizes this risk, as it remains as far as possible from the adjacent level disc spaces.
Ease of use
– Variable angle screws, designed with a wide range of allowable screw trajectories, potentially facilitate screw insertion.
– One-step blocking mechanism features audible, tactile and visual cues to confirm screw is blocked upon insertion.
Because the interbody plate with stops is pre-attached to the spacer, the interbody plate with stops is automatically aligned upon implant insertion. This avoids the process of aligning and realigning an anterior cervical plate.
– Zero-P VA may be used to facilitate surgeries where Zero-P VA is implanted adjacent to a previous fusion. Zero-P VA potentially decreases surgery time and patient complications by reducing the need for removal of existing hard ware from the previous fusion.
– Small incision sizes are possible in comparison to plate and spacer usage.
