Abstract
Objective Lumbar discectomy is the most frequently performed spine surgery, generally resulting in acute relief of symptoms from herniated or bulging discs. Longer term results are less positive, with many patients suffering recurrent herniations and/or continued degeneration. Limited nucleus removal results in reduced back pain, but more frequent reherniation, particularly in patients with large annular defects. Implantation of an annular closure device (ACD) may allow for the advantages of limited nucleus removal without increased reherniation risk. We report here interim results of an ongoing randomized clinical trial (RCT) of an ACD.
