What is a laminectomy?

A laminectomy is a surgical procedure that involves the removal of the bony arches, known as laminae, from one or more vertebrae in the spine. This operation is typically performed to relieve pressure on the spinal cord or nerves, which can occur due to conditions such as spinal stenosis, herniated discs, or tumors that impinge on the neural elements.

By removing the laminae, the surgeon can create more space within the spinal canal, thereby alleviating pain, weakness, or numbness that may be caused by compression of the spinal nerves. This procedure is often part of the treatment for various spinal disorders, providing patients with improved mobility and a reduction in neurological symptoms.

Understanding laminectomy is essential in the medical field, especially when dealing with spinal conditions, since it directly addresses the structural changes in the vertebrae that can lead to significant complications if left untreated.
