This minimally invasive technique is used to remove the herniated portion of a vertebral disc. It is 95% to 98% effective in eliminating leg pain (sciatica) caused by nerve root compression. The procedure is performed through a small incision on the back.
Lumbar microdiscectomy, also known lumbar disc microsurgery, is performed to remove a piece of intervertebral disc that is pressing on a spinal nerve and causing severe pain, weakness or numbness in the lumbar, or lower, back. This pain may extend down the length of the leg, and is then referred to as radicular pain. The lumbar back is the largest moveable segment of the vertebral column and is especially vulnerable to painful disorders, both because it is the part of the spine most affected most by twisting and bending, and because it bears the most body weight.
reasons for A Lumbar Disc Microsurgery
Typically, conservative treatments, such as rest, physical therapy and corticosteroid injections are tried first and, only if patients do not respond to these treatments after a period of 6 weeks, is surgery considered. While surgery is not needed in all cases, lumbar microdiscectomy is considered a highly effective option that can relieve pain quickly. Lumbar microdiscectomy is most often performed to relieve pain caused by lumbar disc herniation. At times, it is also performed to treat a further complication, known as a lumbar disc rupture. A herniated disc is a common condition that occurs because of gradual wear and tear or an injury to one of the intervertebral discs, causing it to bulge beyond the parameters of the spinal column. If the pressure on the disc is great enough, the outer covering of the disc, the lamina, may fracture and break open. This condition is referred to as a ruptured disc.
Lumbar microdiscectomy is a minimally-invasive procedure, performed laparoscopically, in which miniature surgical instruments and a tiny camera are inserted through several small incisions in the back. With this equipment, the surgeon has a magnified view of the affected area and can be extremely precise. Once the surgeon pinpoints the location of the affected disc, the muscles are lifted away to access the spine. The impinged nerve root is identified and the targeted disc is removed to relieve compression. If necessary, a small portion of the facet joint, the joint connecting two vertebrae, may be removed as well. The muscles are then placed back in their original position and the incisions are closed with sutures. This procedure is performed under general anesthesia in a hospital setting. A hospital stay of a few days is usually required after surgery.
