Microdiscectomy, also called Microlumbar Discectomy, is performed for patients with a painful lumbar herniated disc. Microdiscectomy is a very common, if not the most common, surgery performed by spine surgeons. The operation consists of removing a portion of the intervertebral disc, the herniated or protruding portion that is compressing the traversing spinal nerve root. Years ago, most spine surgeons would remove a herniated disc using a rather large surgical incision and surgical exposure without the use of a microscope or telescopic glasses, which would often involve a long hospital stay and prolonged recovery period. Today, many surgeons use a microscopic surgical approach with a small, minimally-invasive, poke-hole incision to remove the disc herniation, allowing for a more rapid recovery. The surgery is performed utilizing general anesthesia. A breathing tube (endotracheal tube) is placed and the patient breathes using a ventilator during the surgery. Preoperative intravenous antibiotics are given. Patients are positioned in the prone (lying on the stomach) position, generally using a special operating table with special padding and supports.
