ZERO-P™ VA Stand Alone Spacer

• 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.
• Designed to prevent contact with adjacent levels. Cervical plates placed near the adjacent level discs may contribute to bone formation near or around the adjacent level,which may lead to future complications.

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 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 hardware from the previous fusion.
• Small incision sizes are possible in comparison to plate and spacer usage.

PEEK interbody spacer 

• Includes a radiopaque marker for posterior visualization during imaging
• Spacer component is made of pure medical grade PEEK Optima (polyetheretherketone)
• Teeth on the superior and inferior implant surfaces provide initial stability
• Titanium alloy interbody plate with stops
• Stresses in the interbody plate with stops are decoupled from the spacer through an innovative interface
• Contralateral safety stops designed to prevent over insertion and align with the anterior surface of thevertebral bodies

Variable angle screws

• Can be inserted 27°– 44° (17° range) in cranial-caudal direction and 15°– 29° (14° range) in medial-lateral direction
• Designed to help prevent graft expulsion
• Self-drilling and self-tapping options
• Screws are allowed to toggle postoperatively within vertebral bodies, which may potentially prevent load
• shielding of the graft in the event of graft subsidence
