Scientists Develop AxioMed Spinal Disc Replacement That Truly Mimics Healthy Human Disc — A Game-Changer in Spine Surgery

By PR Newswire On Nov 18, 2025

Landmark biomechanical study shows AxioMed’s viscoelastic lumbar disc is the first implant to replicate the natural mechanical behaviors of a human disc, unlocking a new era of motion-preserving spine care.

FORT LAUDERDALE, Fla., Nov. 18, 2025 /PRNewswire/ — A groundbreaking scientific milestone has been achieved in spine surgery with the publication of a new peer-reviewed biomechanical study demonstrating that the AxioMed Viscoelastic Total Disc Replacement (VTDR) is the first spinal disc replacement shown to reproduce key stiffness characteristics and natural-like motion behaviors of a healthy human lumbar disc. The study, published in Clinical Biomechanics and now indexed on PubMed, marks a major leap forward in the treatment of degenerative disc disease.

The study, titled “ASTM biomechanical study comparing the AxioMed lumbar viscoelastic disc to human lumbar disc data,” shows that AxioMed’s VTDR reproduces native lumbar-disc biomechanics across axial compression, flexion-extension, and shear — a level of similarity not previously demonstrated in published artificial disc research.

A Breakthrough Decades in the Making

For over 40 years, surgeons and engineers have attempted to create a disc replacement that behaves like a natural disc. Traditional ball-and-socket implants create motion, but not natural biomechanics — often leading to abnormal forces, adjacent-segment disease, and limited long-term success.

This new study demonstrates that AxioMed’s viscoelastic core delivers natural disc-like mechanical behaviors, including:

Stiffness values overlapping native human disc ranges
Natural nonlinear load response
Consistent mechanical performance under physiologic conditions
No implant failures under loads up to 20,000 N

Researchers concluded that the AxioMed VTDR ” reproduces lumbar disc stiffness more closely than prior designs ,” calling it a significant advancement in spinal-motion preservation.

“This study confirms what our team has been working toward for nearly two decades — a spinal disc replacement that does not just move, but truly behaves like the native human disc. This breakthrough represents a new era where fusion is no longer the default solution and patients can regain natural, healthy motion.”

Dr. Erik Spayde

Harvard-Trained Spine Surgeon • Chief Medical Officer, KIC Ventures

“As a spine surgeon trained in both traditional and motion-preservation techniques, I have never seen a disc replacement replicate human biomechanics with this level of fidelity. This is the type of innovation surgeons have been waiting for. AxioMed’s disc has the potential to redefine the standard of care for degenerative disc disease.”

Vito Lore

Chief Technology Officer, KIC Ventures

“Developing a viscoelastic disc that performs like the natural tissue has been one of the most complex engineering challenges in orthopedics. This study validates years of research, testing, and material science innovation. We finally have a disc that behaves like the one we were born with.”

A New Standard for Spine Surgery

Degenerative disc disease affects millions of people worldwide and is one of the leading causes of disability. Traditional spinal fusion eliminates pain but also eliminates motion. AxioMed’s viscoelastic technology aims to restore quality of life by:

Preserving natural range of motion
Reducing adjacent-segment degeneration
Improving load distribution
Offering an alternative to mechanical discs and fusion surgery
Potentially lowering long-term complication rates

This breakthrough places AxioMed at the forefront of a new generation of LESS invasive, motion-preserving spine solutions .

About the Research

The study was conducted using rigorous ASTM mechanical standards at physiologic temperature (PBS at 37 °C). The implant demonstrated behavior consistent with natural disc biomechanics across all tested directions. https://pubmed.ncbi.nlm.nih.gov/41166787/
