Laminectomy is a spinal surgery procedure that involves the removal of a portion of the bone called the lamina, located in the back part of the vertebra. The goal is to relieve pressure on the spinal cord and nerve roots, thus alleviating symptoms such as numbness, muscle weakness, and pain. This pressure can be caused by conditions like herniated discs or spinal stenosis, which can significantly impact daily life and mobility. Laminectomy aims to decompress the nerves, thereby relieving symptoms.
