A Microdiscectomy is a Minimally Invasive Spinal procedure designed to relieve pain as a result of a herniated disc in the lumbar spine. When a disc becomes herniated, the gel-like nucleus material is extruded from the surrounding wall of the spinal disc (annulus). This material enters the spinal canal and presses against the spinal cord or spinal nerves. This often causes pain throughout lower back and into the extremities (known as Sciatica). A Minimally Invasive Microdiscectomy removes the herniated portions of the disc(s) and any bone spurs to alleviate the pain and pressure on the nerves or spinal cord.
