Which best describes a difference between a spinal fusion and a laminectomy?

Spinal fusion is an operation that joins two or more vertebrae so they no longer move independently. A laminectomy removes part of a vertebra, usually the lamina, to relieve pressure on the spinal cord or nerves. Thus, the best description is that spinal fusion joins vertebrae, while a laminectomy removes a portion of a vertebra.
