Patients' Guide to Non-Fusion, Motion Preserving Treatment for Lumbar Spinal Stenosis
coflex® Interlaminar Stabilization™ Technology

Patients From the coflex® Study Outperformed Fusion Patients in All Clinical Measurements*

Reginald Davis, MD—Principal Study Investigator, Comment

The coflex® procedure was studied and compared to pedicle screw fusion surgery after decompression in an U.S. Food and Drug Administration (FDA) clinical trial.

The coflex® Interlaminar Stabilization™ device is a non-fusion implant that preserves motion Fusion surgery uses rods and pedicle screws for rigid fixation


The study's principal investigator, Reginald Davis, MD stated, "This is the first time a new spinal technology is proven to be better and more effective than the historical gold standard and is still actually lower cost. I am excited to be able to provide coflex® to my patients without the need for fusion through a simple, motion preserving, and minimally invasive bone saving surgical technique."2

Patients from the coflex® study 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 years
  • coflex® 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 weeks
  • coflex® 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)

*This data is based on validated pain and function measurements from a randomized FDA clinical study comparing the coflex® Interlaminar Stabilization™ technology to pedicle screw fusion surgery for moderate to severe spinal stenosis.
