Laminectomy is a surgical procedure that involves removing a portion of the lamina, which is the bony arch of the vertebrae in the spine. This operation is typically performed to relieve pressure on the spinal cord or nerves caused by conditions such as herniated discs, spinal stenosis, or tumors. By creating more space in the spinal canal, laminectomy can help alleviate pain, numbness, and weakness in the limbs. The procedure is usually done under general anesthesia and may involve a hospital stay. Recovery times can vary, but many patients experience significant improvement in their symptoms after surgery. Physical therapy may be recommended to aid in rehabilitation and strengthen the back muscles.
