ClosedDescription of Medical Service
Towards the end of a spinal discectomy procedure, once the herniated disc material is removed, and confirmation of the annular defect is within indicated size, the Barricaid® mesh is placed on the inner surface of the disc annulus using fluoroscopic guidance and secured to the surrounding vertebral bone with the titanium anchor. The mesh remains within the posterior intervertebral space to occlude the opening created during discectomy. Placement of the mesh takes an additional 10 to 15 minutes just prior to wound closure in a surgery that takes approximately 2 hours.The Barricaid® prosthesis (Intrinsic Therapeutics, Massachusetts, USA) is a small piece of flexible polymer mesh composed of multiple layers of non-degrading polyethylene terephthalate fibres attached to a titanium bone anchor. The mesh, which contains a platinum-iridium marker that makes it visible on x-ray images, comes in various widths (8, 10 and 12mm) is preloaded in a single-use delivery system

• a disc height of 5 mm; and,
• intraoperative confirmation of an annular defect that is between 4mm-6mm in height and between 5mm and 12mm in width
