Cohort radiographs sample
Draper, Utah, September 11, 2025 / PRNewswire / – Nexus Spine is excited to share the results of the pilot study of a comparative radiographic evaluation of ACDF’s results in a series of patients who were selected by common risk factors for sinking, instability and delayed bone growth. Specifically, patients were over 66 years old, had poor bone quality and/or required cervical fusion surgery at three or more contiguous levels. Each patient received a cervical interboda cage Nexus Spine Tranquil® at one or more spinal levels and, as control, some patients received one or more competitors interbody devices at adjacent levels.
The postoperative radiographic evaluation of the levels treated in each of the two weeks, six weeks, six months and twelve months revealed that the levels treated with the Nexus Spine interboder devices had no measurable sinking. In contrast, the levels treated with the other interbody devices demonstrated a measurable sinking as soon as two weeks in more than 66% of the treated levels. Sinking is a primary indicator of column instability and pain. Consequently, the results of this study suggest that Nexus Spine’s patented technology is equivalent to a significant improvement on competitors.
Publications reviewed by peers demonstrate competitive devices that exhibit at least 3 mm sinking in more than 52% of patients. Nexus Spine’s Interbody® cages had much better performance, without sinking.
This comparative study was designed and made independently by Dr. Peter Campbell, of Shreveport, La, without funds, control or contributions of the Nexus column. Dr. Campbell shared: “My radiographic results made it clear that Calm was the only device that improved the sinking. Compared to other devices currently available in the market, Calm does not decrease.”
“If we can resolve the key challenges for the greatest risk patients,” said David Hawkes, president of Nexus Spine, “then we can improve the universal care standard.” David also explained: “Combining the rigidity of the host bone is key. This pilot study is very exciting because it shows that our patented intermediate implants are better to prevent sinking. We are also seeing how quickly our devices provide stability.
