Coflex Surgery

Have you ever asked yourself any of the following questions?
Does the pain radiating down your legs, buttocks or lower back prevent you from walking long distances?
Do you experience weakness, tingling, numbness, stiffness, or cramping in your legs, buttocks or lower back, especially during physical activity?
Do you tend to lean on the shopping cart at the grocery store to help relieve your pain?
Is pain medication or physical therapy no longer effective?

The coflex® Solution could help patients like you with spinal stenosis become independent and functional again.

If you and your doctor are discussing various treatment options, consider the new non-fusion solution:

The spinal stenosis treatment option that gets you walking again

What is Lumbar Spinal Stenosis?

Lumbar spinal stenosis is a narrowing of the spinal canal in your lower back. People who have spinal stenosis are not able to walk for long periods of time.

Pinched Nerve from Stenosis


A. Lateral Spinal Stenosis

  1. Pinched Nerve from Stenosis

B. Central Spinal Stenosis

  1. Spinal Canal
  2. Stenosis

What Causes Lumbar Spinal Stenosis?
The most common cause of lumbar spinal stenosis is the “wear and tear” that occurs with the natural aging and degeneration process. As we age, the tissue in our lower spine that connects bones together (ligaments) may start to thicken and harden from arthritis, discs may start to collapse and bulge (or herniate), and bone spurs, known as osteophytes, may grow on bone in the spine. All of these things narrow the amount of space in the spinal canal, reducing the nerve’s ability to exit to your lower extremities. Therefore, the nerves in the lumbar spine become pinched, causing pain in the lower back, buttocks and legs. Pain is especially notable with physical activity or when walking, and may be relieved by sitting or leaning forward.

Treatment Options

Non-Surgical Treatment options

Once your doctor has told you that you have spinal stenosis, treating the condition usually starts with non-surgical treatment options.

Non-surgical options include:

  • Patient Education
  • Rest Or Restricted Activity
  • Weight Loss
  • Medication
  • Chiropractic Care
  • Massage
  • Acupuncture
  • Physical Therapy
  • Exercise
  • Injections
Surgical Treatment options
if your pain cannot be controlled with non-surgical treatment options, a surgical procedure may help relieve you of your pain from spinal stenosis.

Surgical options include:

  • Decompression. In a surgical decompression procedure, your surgeon removes the bone and soft tissue that is putting pressure on the nerves of your spinal canal.
  • Surgical Decompression with Spinal Fusion. A surgical decompression procedure may cause the spine to become unstable. in this case, spinal fusion surgery may be used to provide stability to your spine. The surgeon uses metal rods and screws to hold the bones in place while the vertebrae fuse together. The fusion stops the motion in that portion of your spine.
  • Surgical Decompression with coflex® Non-Fusion Interlaminar Stabilization™. A surgical decompression procedure may cause the spine to become unstable. The coflex® Solution provides stability to your spine without the need to fuse your vertebrae bones together. The coflex® device is a metal implant that goes in the back of your spine after decompression to provide stability while maintaining the motion in your spine. The coflex® implant also helps keep normal height in the area where nerves leave the spine (foramen) so they can exit freely without being pinched.
What Is Coflex® Surgery?

The coflex® device is a small, titanium implant that goes in the back of your spine to treat moderate to severe spinal stenosis. After you receive anesthesia and are prepared for surgery, the surgeon makes a small incision in your back and performs a surgical decompression, which includes the removal of bone and soft tissue in and around your spine. This surgery takes the pressure off your nerves that are causing you pain.The surgeon then inserts the coflex® device through the same incision until it is secured on the laminar bone, which is the strongest bone in the back of your spine.

How Does Coflex® Work?

The coflex® device is specifically designed to help keep your spine stable after a decompression surgery. The coflex® device also maintains the normal height between your vertebral bones so your nerves can exit the foramen and extend to your lower extremities.

Also, the coflex® device doesn’t fuse your vertebral bones together, so motion and natural movement are kept in your spine at the operated area, as well as in the neighboring parts of your spine. It is strong yet simple, and flexible enough to support your spine without having to fuse your bones together. The coflex® device allows your vertebral bones to move in a controlled way so the decompressed area is not unnaturally stiffened or fused!

FDA Tested and Approved

The coflex® procedure was studied and compared to pedicle screw fusion surgery after decompression in a FDA clinical trial. The coflex® patients outperformed fusion patients in all clinical measurements!*coflex® patients were more satisfied with their outcome

  • 94% of coflex® patients were satisfied with their outcome, compared to 87% of fusion patients at two yearscoflex® patients had faster relief of their symptoms
  • 90% of coflex® patients had early relief of their spinal stenosis symptoms, compared to 77% of fusion patients at six weekscoflex® patients had lasting relief of their symptoms
  • 88% of coflex® patients had lasting relief of their spinal stenosis symptoms, compared to 78% of fusion patients at two years coflex® surgeries were 36% faster compared to fusion surgeries (98 minutes vs. 153 minutes) coflex® patients stayed one less day in the hospital compared to fusion patients (1.9 days vs. 3.2 days) coflex® patients had less blood loss during surgery compared to fusion patients (110cc vs. 349cc)

As a patient, there is always potential risk in having surgery or when receiving a medical device. usually these risks are rare and the coflex® Patient Labeling should be referred to for a list of all potential risks and hazards observed during the clinical study. For patients receiving coflex®, the risks included continued pain, wound healing problems (such as infection or drainage), brief numbness or tingling in the arms or legs, and bone fractures. in some patients, the coflex® surgery may not help your pain, and you may need another surgery to remove the device. it is hard to predict who will not benefit from this surgery.

Every patient is different; therefore, results may vary. All data is on file at Paradigm Spine, LLC.
