Abstract:Postoperation relapse of lumbar disc herniation (prLDH) compressions of lumbar nerves are prone to cause failed back surgery syndrome (FBSS). Because the blood supply to the annulus is mainly from the small vessels of the peripheral segmental artery branches, the formation of annulus scar takes 3-6 months. The intensity of the new scar formed at the rupture is low. When the pressure in the intervertebral disc increases rapidly, the residual nucleus pulposus will protrude again from the scar. At the same time, the inflammatory factors in the spinal canal enter the intervertebral disc through the annulus fibrosus rupture, which further aggravates the degeneration of the intervertebral disc. It has been reported that annular fiber repair can promote the healing of lacerated scar, significantly enhance the hardness of scar, reduce the re-protrusion rate of nucleus pulposus, and reduce the possibility of postoperative revision. With the popularity of the concept of minimally invasive spine surgery, the current way of fibrous ring repair has gradually changed from open laminae fenestration surgery to endoscopic minimally invasive surgery. Therefore, this paper reviews the different surgical procedures for descending annular fiber repair.
