Detailed Description:
The Barricaid is indicated for patients with radiculopathy (with or without back pain), a positive Straight Leg Raise (L45, L5S1) or femoral stretch test (L12, L23, L34), and a posterior or posterolateral herniation at one level between L1 and S1 with radiographic confirmation of neural compression using MRI who are found to have an annular defect (post discectomy) which measures between 4mm and 6mm tall and between 6mm and 10mm wide, have a minimum posterior disc height of 5mm, and have failed at least 6 weeks of conservative treatment.

Ages Eligible for Study:   21 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Age 21 to 75 years old and skeletally mature (male or female).
  • Patients with posterior or posterolateral disc herniations at one level between L1 and S1 with radiographic confirmation of neural compression using Magnetic Resonance Imaging (MRI).
  • At least six (6) weeks of failed, conservative treatment prior to surgery
  • Oswestry Disability Index (ODI) Questionnaire score of at least 40/100 at baseline.
  • Visual Analog Scale (VAS) leg pain (one or both legs) of at least 40/100 at baseline.
  • Psychosocially, mentally and physically able to fully comply with the clinical protocol and willing to adhere to follow-up schedule and requirements.

  • Any metabolic bone disease.
  • Subject has insulin-dependent diabetes mellitus.
  • Subject has been diagnosed with active hepatitis, acquired immunodeficiency syndrome (AIDS), or Human immunodeficiency virus (HIV).
  • Subject has been diagnosed with rheumatoid arthritis or other autoimmune disease.
  • Subject has a known allergy to titanium, polyethylene or polyester materials.
  • Any subject that cannot have a baseline MRI taken.
  • Subject is pregnant or interested in becoming pregnant in the next three (3) years.
  • Subject has active tuberculosis or has had tuberculosis in the past three (3) years.
  • Subject is currently involved in another investigational study.
  • Any contraindication for MRI or Computed tomography CT scan (e.g. claustrophobia, contrast allergy).
