“Conventional plate/cage constructs or stand-alone interbody devices have been the accepted method of fixation for ACDF procedures, but each comes with its own nuances and potential compromises. The V3 progressive technique combines the best attributes of both methods into one system and eliminates their drawbacks. We designed the V3 system to complement our HiJak AC, the first and only expandable cervical interbody on the market, launched earlier this year. With the positive clinical results from HiJak and the interest we are seeing from surgeons regarding the V3 system, we’re confident that the combination of the two will be the next evolution in cervical fixation,” said Matt Baynham, Atlas’ CEO.
V3 versus Conventional Plating
The V3 segmental approach reduces the amount of dissection and retraction required to perform an ACDF by promoting the use of smaller, less invasive, individual plates for multi-level constructs. Published data has shown this methodology yields greater fusion rates for three and four level constructs when compared to conventional plating1. This philosophy promotes load sharing at each level, a key factor in healthy fusion, and avoids the risk of the stress shielding seen in single piece multi-level plates. Combined with the customizable HiJak interbody that offers adjustable lordosis up to 20 degrees, the V3 system gives the surgeon the opportunity to address each diseased segment individually. “No other system allows for this custom approach to cervical fixation. The surgeon can now tailor the implants to meet their patient’s specific needs and more easily accomplish their surgical objectives,” said Baynham.
The unique V3 guidance system provides surgeons the opportunity to temporarily dock the plate onto the face of the HiJak device providing ease of use and control during the installation process. The guidance feature eliminates “fiddle” often associated with “chasing” a plate while offering easier alignment for multi-level constructs, and optimized plate length to avoid adjacent level encroachment.
V3 versus Standalone
In comparison to zero profile type stand-alone devices, the V3 system offers increased rigidity by placing the plate on the anterior aspect of the vertebral body2, 3. The V3 plate allows an easier to achieve screw angulation avoiding the difficulty associated with angled drivers and the risk of skiving/violating the endplate as often seen with zero profile systems. The segmental technique has been shown to have greater fusion rates than standalone devices for both single and multi-level constructs1, 4.
Atlas will be exhibiting at NASS in Chicago this year at booth number 4527. Atlas is actively recruiting distributors to service its innovative product line with nationwide hospital contracts.
