Laminectomy is a type of spinal decompression surgery. It allows for decompression of the nerves in the lower back or the lumbar area. Such pressure or compression on the nerves due to herniated or slipped disc, spinal injuries, or arthritis can be very painful. With age, many people suffer from bony growths in the spinal column causing such compression. This compression can cause pain and mobility issues. During the surgery, the orthopaedic surgeon or the neurosurgeon makes an incision in the skin over the affected part of the spine. The surgeon then cuts away a part of the bone and the ligament or the lamina relieving the compression on the nerves. This may or may not be combined with a spinal fusion – a grafting of the bones of the vertebrae. The person undergoing a laminectomy surgery may need help getting up and moving around for a few days.
