Keep Moving: How COFLEX® Motion Preservation Therapy Offers a Strong Alternative to Spinal Fusion
Has your doctor suggested spinal fusion as the solution for your spinal stenosis? You might want a second opinion. Fusion can limit your mobility, even after surgery. There's another way.

If spinal stenosis is affecting your ability to walk, stay active, or enjoy everyday activities, you may be looking for treatment options that do more than relieve your symptoms. You may also be wondering whether spinal fusion is your only surgical option.

At Seattle Spine Institute in Seattle, Washington, our experienced spine specialists offer COFLEX®, a motion-preserving treatment for patients with lumbar spinal stenosis who are seeking an alternative to traditional spinal fusion.

What is spinal stenosis?

Spinal stenosis occurs when the spaces within the spine become narrowed, putting pressure on nearby nerves. This condition most commonly develops in the lower back as age-related changes affect the discs, joints, and other structures that support the spine.

Symptoms can vary, but may include:

  • Lower back or leg pain
  • Numbness or tingling
  • Leg heaviness or fatigue while walking
  • Sciatica or pain that travels down one leg
  • Muscle weakness
  • Changes in balance or walking

Many people notice that their leg symptoms improve when they sit or bend forward. Over time, spinal stenosis can make activities such as walking, standing, or exercising increasingly difficult.

What is COFLEX®?

COFLEX is a small, titanium implant designed to relieve pressure on the nerves while helping preserve motion in the spine. Unlike traditional spinal fusion, which joins two or more vertebrae together to create stability but may result in stiffness, COFLEX is a non-fusion, motion-preserving procedure.

The goal is to decompress the affected nerves while maintaining more of the spine’s natural movement. The COFLEX U-shaped interspinous device supports your spine without causing the rigidity common with spinal fusion.

For the right patients, COFLEX provides an alternative to traditional decompression with fusion surgery. Your surgeon removes the tissue causing nerve compression before placing COFLEX implant between the affected vertebrae to help maintain space and support your spine.

How is COFLEX different from traditional spinal fusion?

Spinal fusion is designed to stabilize the spine by joining vertebrae together in a rigid connection. COFLEX takes a different approach. Rather than fusing the treated segments, it is designed to preserve motion while providing support after decompression.

That distinction can be important for patients who want to maintain as much natural spinal movement as possible. COFLEX is not right for everyone, and your spine specialist will evaluate your symptoms, imaging, overall spinal health, and treatment goals before recommending it.

Every spine is different, and the best treatment depends on your individual condition. If spinal stenosis is limiting your mobility or affecting your quality of life, it is worth discussing all of your surgical options.

At Seattle Spine Institute, we can help you understand whether COFLEX or another treatment approach is appropriate for you.
