This interactive video gives a clear picture of how a microdiscectomy [1] can help relieve leg pain [2] (sciatica [3]) and/or back pain caused by a Herniated Disc [4]. In this type of spine surgery, the spine surgeon removes the portion of the herniated disc that is pinching the nerve [5] and causing pain.
