Lumbar laminectomy is an operation performed on the lower spine to relieve pressure on one or more nerve roots. The term is derived from lumbar (lower spine), lamina (part of the spinal canal's bony roof), and -ectomy (removal).

Pressure on a nerve root in the lower spine, often called nerve root compression, causes back and leg pain. In this operation the surgeon reaches the lumbar spine through a small incision in the lower back. After the muscles of the spine are spread, a portion of the lamina is removed (Fig. 2) to expose the compressed nerve root(s).

Pressure is relieved by removal of the source of compression part of the herniated disc, a disc fragment, a tumor, or a rough protrusion of bone, called a bone spur.

Successful recovery from lumbar laminectomy requires that you approach the operation and recovery period with confidence based on a thorough understanding of the process. Your surgeon has the training and expertise to correct physical defects by performing the operation; he and the rest of the health care team will support your recovery. Your body is able to heal the involved muscle, nerve, and bone tissues. Full recovery, however, will also depend on your having a strong, positive attitude, setting small goals for improvement, and working steadily to accomplish each goal.
