DIAMTM stands for Device for Intervertebral Assisted Motion and is for the treatment of moderate low back pain secondary to degenerative disc disease.

The DIAMTM implant is in clinical use since 1997, and more than 190,000 have been successfully treated to date.

What is the clinical problem?

As discs lose their water content because of disease or age, they lose their height, bringing the vertebrae closer together. As a result, the nerve openings in your spine become narrow and the discs don’t absorb the shocks as well. Wear and tear, poor posture and incorrect body movements can also weaken the disc, causing degeneration. Disc degeneration not only causes back pain but may also cause functional problems such as tingling or numbness in your legs or buttocks, or difficulty walking. Doctors call this degenerative disc disease (DDD).

How does DIAMTM work?

The DIAMTM Spinal Stabilization System implant is a dynamic stabilization product that can be used as an interventional solution to treat low back pain and radiating leg pain. The core of the DIAMTM device is made of silicone. The outermesh and tether are made of polyethylene (polyester.) The crimp is titanium. The first DIAMTM device surgery was performed in 1997. Since then, thousands of cases have been performed.

Who DIAM™ is intended for

The DIAMTM Spinal Stabilization System is an interventional solution indicated for skeletally mature patients that have moderate low back pain (with or without radicular pain) with current episode lasting less than one year in duration secondary to lumbar degenerative disc disease (DDD).

DDD is confirmed radiologically with one or more of the following factors:

  • Patients must have greater than 2mm of decreased disc height compared to the adjacent level
  • Scarring/thickening of the ligamentum flavum, annulus fibrosus, or facet joint capsule
  • Herniated nucleus pulposus

What are the potential benefits?

The benefits of the DIAMTM procedure are relatively clear. After the device is implanted, the patient may experience less pain and return to many of their normal activities.

The potential advantages of surgery with the DIAMTM Spinal Stabilization System include:

  • Relief of painful symptoms

  • Restoration of disc height

  • Increased spinal stability

  • Controlled motion
