Abstract
Operative methods are changing from aggressive open methods to less invasive methods including microscopic discectomy and various kinds of percutaneous methods. In spite of having definite advantages, percutaneous methods still have limited indications and no uniformly convincing clinical results. Microscopic discectomy has advantages of those of open methods and percutaneous methods. A review of clinical results of operative treatment for lumbar disc herniation shows favorable longterm results. For the better longterm results, we should understand the proper indications of each treatment modalities.
