Spinal fusion A spinal fusion is a surgery to weld together two vertebrae. Vertebrae are the bones that make up the spine.
Discectomy Intervertebral discs are located between each backbone (vertebra). When damaged, these discs can put pressure on nerves as they leave the spinal cord. An intervertebral discectomy is a back surgery that removes all or part of these discs. The procedure is most often done on lumbar discs (located in the lower back). It may also be done on cervical discs in the neck.
