Posterior laminectomy and fusion is a surgical procedure designed to relieve pressure on the spinal cord or nerves caused by conditions such as spinal stenosis, herniated discs, or degenerative spine disease. During the procedure, the surgeon removes the lamina—the back part of the vertebra that covers the spinal canal—to create more space and relieve pressure. Following the laminectomy, a spinal fusion is performed to stabilize the spine. This involves placing rods and screws in the vertebrae, sometimes bone grafts or implants between the affected vertebrae, which will eventually fuse together, providing stability and reducing pain.
