| lumbar disk removal | A surgical procedure which is designed to relieve pressure on the spinal cord or nerve root that is being caused by a slipped or herniated disk in the lumbar spine. This procedure is also used in the treatment of spinal stenosis. This procedure includes removal of a portion of the bone comprising a vertebra. Recovery is generally 7-10 days. An alternative to this is a micro-disc surgery. (27 Sep 1997) |
