This lumbar disc microsurgery is a minimally-invasive procedure relieving pressure on nerve roots caused by a herniated disc. It can eliminate the pain of sciatica.
After anesthesia is administered, the surgeon creates a small incision in the skin of the back. The muscles and tissues are pushed aside to allow access to the spine. The surgeon then creates a small window in the lamina, a portion of vertebral bone that covers the spinal canal. The surgeon then places instruments through this window.
The spinal nerves are gently moved aside, and the surgeon clears away the herniated portion of the vertebral disc. This relieves painful pressure on the nerves. The rest of the disc is left in place, where it will continue to cushion the vertebrae.
