Lumbar laminectomy, also known as decompression laminectomy, is a spinal surgery done to relieve excess pressure on the spinal nerve(s) in the lumbar (low back) region.
The term laminectomy originated from the Latin words ‘lamina’ refers to a thin plate and the word ‘ectomy’ means removal. The purpose of laminectomy is removal of the lamina or roof of the vertebra so as to provide enough space for the nerves to exit the spinal canal (decompression).
When lumbar laminectomy is indicated?
Spinal stenosis is one of the major indications for lumbar laminectomy. It is a condition of narrowing of spinal canal due to arthritic changes of facet joints and intervertebral discs. This causes enlargement of the joint that exerts pressure on the spinal nerves.
Symptoms of nerve impingement are back pain or radiating pain into the hips, buttocks or legs, numbness or tingling sensation and muscle weakness in the back and lower extremities.
What is the procedure of lumbar laminectomy?
Lumbar laminectomy is usually performed under general anesthesia. In this technique, the patient lies face down on the operating table. A small incision is made along the midline of the back. To have a clear view of the spine, the surgeon slowly retracts the soft tissues and muscles. A part of or the entire lamina is removed to eliminate the pressure on the nerve roots. In addition, other sources of compression such as bone spur or damaged disc is removed to relieve the symptoms. At the end of the procedure, the surgeon realigns the soft tissues and the incision is closed.
