In our practice here in Huntington, I see patients almost daily who've been told their disc problem is permanent. They've tried physical therapy, anti-inflammatory medications, cortisone injections. Many of them don't know that there's a sophisticated technology, developed over decades and FDA-cleared for specific spinal conditions, that can actually reverse the pathomechanics of their disc herniation or bulge. That technology is VAX-D: Vertebral Axial Decompression.

The Origin and FDA Clearance

VAX-D was developed by Dr. Allan Dyer, purpose-built to create negative intradiscal pressure strong enough to draw herniated or bulging disc material back toward the center of the disc. The FDA granted 510(k) clearance to VAX-D in 1995 for the treatment of herniated discs, bulging discs, and spinal stenosis — based on clinical data demonstrating measurable, repeatable results.

How VAX-D Creates Negative Intradiscal Pressure

VAX-D uses a logarithmic decompression curve — a mathematically-designed pattern of increasing and decreasing force over 90 seconds. The device creates negative intradiscal pressure in the range of -150 to -160 mmHg. This acts like a vacuum, drawing herniated disc material back into the disc space, rehydrating the disc, and allowing the annulus fibrosus to heal. Critically, this is achieved without triggering "muscle guarding" — the protective reflex that makes conventional traction ineffective.

Why This Matters Clinically

The Ramos and Martin study measured intradiscal pressure directly during VAX-D treatment — confirming the negative pressure is real and measurable. The Tilaro study showed an 86% improvement rate in patients with herniated discs and sciatica treated with VAX-D.

The Typical Treatment Protocol

Patients usually undergo 20 to 28 sessions over 4 to 6 weeks, typically 4 sessions per week initially. Each session lasts about 30 minutes.

What Conditions Respond to VAX-D?

In our practice, we use VAX-D for herniated discs, bulging discs, degenerative disc disease, sciatica caused by disc pathology, and spinal stenosis related to a bulging disc.

What About Surgery?

VAX-D isn't for everyone — not for cauda equina syndrome or progressive neurological deficit. But for the majority of patients with a contained disc herniation or bulge, VAX-D offers a legitimate alternative to surgery that avoids the risks of infection, scar tissue, and adjacent level degeneration.

Next Steps

If you're in the Huntington or West Hills area and want to discuss whether VAX-D might help your condition, give us a call at (631) 659-2980. The first step is an evaluation — we'll review your imaging and discuss whether VAX-D makes sense for your specific situation.
