Transforming the future of back pain treatment

SpinaFX is a medical treatment solution company providing rapid and sustained relief to patients with back pain due to contained lumbar herniated discs, using innovative, minimally invasive image-guided therapy.

Back Pain is the #1 cause of disability in the world 1 and the most expensive health condition treated2 .

Filling a Therapeutic Gap for Contained Herniated Disc-Related Back and Leg Pain

Lumbar disc herniation affects between 5 and 20 adults per 1,000 annually.3 For many of these patients, there is a gap in treatment options for contained lumbar disc herniation that would fall between conservative care and surgery. Some find conservative treatment options address their symptoms but fail to treat the root cause of pain. For others, surgery could be an undesired option.

Pioneering minimally invasive, image-guided treatments

At SpinaFX Medical, we are committed to filling the therapeutic gap in treating radiculopathy by bringing innovative, minimally invasive, image-guided treatments to market. Using our patented technology backed by published clinical data, we aim to address and eliminate low back and leg pain for the benefit of patients, physicians, facilities, and payers.

A New Treatment Option for Radiculopathy

Clinically backed, patented technology from SpinaFX Medical

Our flagship treatment solution aims to relieve back and leg pain caused by a contained herniated disc through the intravertebral injection of a mixture of oxygen and ozone gas.1 This technology is not currently available for promotion or sale.

Promising research shows there is a potential for oxygen-ozone injections to help treat radiculopathy caused by a contained herniated lumbar disc. In fact, a study of 283 patients showed intradiscal ozone injections are associated with a statistically significant volume reduction of the herniated lumbar disc2. An average disc volume reduction was seen in 96.1% of treated disks six months after treatment2* Animal studies and mathematical modeling have shown a 6% nucleus pulposus volume reduction can lead to a 9.84% reduction in pressure, relieving nerve root compression and herniated disc-related pain.3

        * Average disc volume reduction (mean 7.7+/-5.45%; range, 0.29%-22.31%). P < 0.0001.

How Ozone (O3) works

Ozone (O3) – a dehydrating, oxidizing, naturally occurring species of oxygen (O2) gas that can be injected into the gelatinous disc nucleus.
Nucleus Pulposus Breakdown
Ozone injected into the disc nucleus dehydrates and breaks down proteins* in the nucleus leading to reduction of the bulging disc herniation.

* Glycosaminoglycans (GAGs)-substituted proteoglycans

Reduces Inflammation
reduces inflimation
Ozone reduces the release of inflammatory proteins (cytokines) that lead to inflammation.
Niu 2018, Murphy 2016, Fuccio 2008, Chang 2005 Lu 2017,
Reduces Infection
Ozone has proven antimicrobial properties. Reduced spine infection reduces potential degenerative (modic) changes in the disc, vertebral bones and reduces pain.

Avoiding Later Surgery
17/24 (71%) of Ozone patients avoided open surgery entirely3.
(Surgery can be done after triojection if needed in future)
2/17 (12%) of surgical patients required repeat surgery for persistent symptoms.
