About this product

Division: Spine
Category: Anterior Cervical Discectomy & Fusion

ZERO-P™ is a stand-alone anterior cervical interbody fusion 1-4 device designed to combine the functionality and benefits of a cervical interbody spacer and an anterior cervical plate.

ZERO-P is designed to offer two key advantages over traditional anterior plating systems:

  1. reduce the risk of contacting local anatomical structures and
  2. prevent contact with adjacent levels thereby reducing unintentional ossification.5

ZERO-P features four rigid locking screws for fixation into adjacent vertebral bodies. The four rigid locking screws provide more rigid fixation in Flex-Ex and Axial rotation than similar devices featuring two non-rigid screws.*
