Microdiscectomy

Microdiscectomy (also known as microdecompression or microdiskectomy) is a type of neurosurgery that is commonly used to treat patients suffering from a herniated lumbar disc. In this procedure, a small part of the bone over the nerve root or disc material under the nerve root is removed to relieve neural impingement and provide more room for the nerve to heal.

Procedure

The procedure is performed under general anesthesia. The patient is placed face down on the operating table. The surgeon makes a small incision in the midline of the back and moves the muscles away from the vertebrae. Using a microscope or other magnifying device, the surgeon removes a small portion of the bony arch on the back of the vertebrae (lamina). If the disc has herniated, the surgeon will also remove the portion of the disc that is pressing on the nerve.

Recovery

Most patients are able to return home the same day as the surgery. The recovery period can vary depending on the individual patient and the extent of the surgery. Most patients are able to return to their normal activities within a few weeks.

Risks and Complications

As with any surgery, there are risks involved with a microdiscectomy. These can include infection, bleeding, nerve damage, and a possible allergic reaction to the anesthesia. There is also a small risk that the disc will re-herniate in the future.
