Category: Anterior Cervical Discectomy and Fusion
ZERO-P VA™ Spacer is a stand-alone anterior cervical interbody fusion device designed to combine the functionality and benefits of a cervical interbody spacer and an anterior cervical plate.1-4
The ZERO-P VA Spacer is designed to both minimize contact with local anatomical structures and to prevent contact with adjacent level discs. ZERO-P VA Spacer features two variable angle screws for fixation into adjacent vertebral bodies.
ZERO-P VA Spacer is designed for surgeons focused on ease of use and/or surgeons preferring non-rigid screw constructs.

The DePuy Synthes ZERO-P VA is a stand-alone anterior cervical interbody fusion device indicated for use in skeletally mature patients with degenerative disc disease (DDD) with accompanying radicular symptoms at one level from C2-T1. DDD is defined as discogenic pain with degeneration of the disc confirmed by history and radiographic studies. These patients should have had six weeks of non-operative treatment. The interior of the spacer component of the Synthes ZERO-P VA should be packed with autogenous bone graft and implanted via an anterior approach.
One of the risks of any surgical procedure is death. Other potential risks which may require additional surgery, include:
*These risks can also be associated with general risks of surgery.
Discard and DO NOT USE previously opened or damaged devices. Use only devices that are packaged in unopened and undamaged packages. DO NOT USE if there is a loss of sterility of the device. DO NOT USE past the expiration date.
The DePuy Synthes ZERO-P VA cervical intervertebral body fusion devices are sterilized by gamma radiation. DO NOT RESTERILIZE. CONTENTS STERILE UNLESS INNER PACKAGE IS OPENED OR DAMAGED.
Components of ZERO-P VA should not be used in conjunction with components of, competing systems not manufactured by Synthes. In addition, mixing titanium or titanium alloy with stainless steel implant components is not recommended for metallurgical, mechanical and functional reasons.
|Zero profile midline||
Designed to minimize contact with local anatomical structures.
Designed to prevent contact with adjacent level discs.
May be used to facilitate surgeries where Zero-P VA is implanted adjacent to previous fusions
|Two variable angle screws||Screws may be inserted at shallower angles; larger allowable range for screw insertion (17° range cranial-caudal, 14° range medial-lateral)|
|Contra-lateral safety stops added to interbody plate||Designed to minimize risk of over insertion in the posterior direction during initial insertion and during final tightening|
|One step passive screw securing.||Audible, visual, tactile cues to indicate secured screw.|
|2 footprints, 8 heights, 3 sagittal profiles||Multiple implant options designed to accommodate various patient anatomy|
