The discectomy dilemma

  • When disc material is herniating through a defect in the outer ring of the disc, called the anulus, pressure is being placed on the nerves, causing pain.
  • If indicated for surgery, a discectomy is typically performed. The surgeon removes the bulging or sequestered disc material, reducing or eliminating pressure on the nerves.
  • Removal of disc material usually leaves a hole in the anulus, which opens the potential for reherniation and possibly re-operation.
  • To reduce the possibility of reherniation, surgeons may decide to remove most of the material inside the disc. While this may be effective in reducing the risk of reherniation, literature show that it may lead to a progressive loss of disc height, resulting in chronic and worsening back pain over time.
  • The Barricaid® Prosthesis for Partial Anulus Replacement is the first available method for surgeons to directly close the hole in the disc following discectomy surgery.
  • The Barricaid® is designed to help surgeons address the challenge of reherniation, while preserving the patient’s disc.
