Barricaid is one of the most studied devices in spine.

  • Level 1 RCT with 5 year follow up
  • FDA PMA Approved
  • 10,000+ implantations
  • 70+ peer reviewed publications
  • Proven superior vs. discectomy alone:
    significant reduction in reherniations,
    reoperations, and readmissions

*Some studies outside US indications. Values at Minimum 1 year Post-Op. Minimum study size of 20 Barricaid patients

*Single arm studies are compared to a published cohort of primary discectomy only subjects with large annular defects. Values are reported at one year post-op, unless otherwise indicated.

§ Weighting based on number of Barricaid implants in study at that timepoint.

§ Some of the referenced studies include data from implant sizes not available in the United States or from use of the Barricaid outside of the United States indications for use.

Life has risks. Reherniation shouldn’t be one of them.
