Abstract
Methods for treating a defect in an annulus fibrous are described. The annulus fibrosis has an outer layer, at least one inner layer, and a defect extending through the outer and inner layers. An implant is inserted into the defect in the annulus fibrosis, the implant having at least one aperture. The implant is advanced distally beyond the outer layer in the annulus fibrosis and positioned to occlude the defect. An elongate fixation element is inserted through the at least one aperture, the elongate fixation element having a first end region and a second end region. The elongate fixation element is positioned such that the first end region is within the at least one aperture. The second end region of the elongate fixation element is anchored to the annulus fibrosis. The implant prevents escape of nucleus pulposus through the defect.
