Laminectomy
Modern MedicalLaminectomy is spinal surgery that removes the lamina, the back part of a vertebra, to make more room for the spinal cord and nerves. It is commonly used for spinal stenosis, where narrowing of the spinal canal squeezes the nerves and causes leg pain, numbness or weakness when walking. It may be combined with other procedures to keep the spine stable.
