A laminectomy relieves nerve pressure and pain caused by spinal stenosis. Spinal stenosis is a narrowing of the spinal canal that puts pressure on the nerves and causes pain throughout the spine and extremities. It can develop as a result of bone spurs or just from aging. In this procedure, a small section of bone that covers the back of the spinal cord, called the lamina, is removed to relieve the compression.
A laminectomy is performed through the back of the spine under general anesthesia. The removal of the lamina and any bone spurs relieves the pressure on the spinal cord. The remaining spine bones can be connected by titanium metal rods with screws attached to bones on each side. The procedure can also be done without fusion.
