Neurosurgery is the surgical discipline focused on treating central, peripheral nervous system and spinal column diseases.
Laminectomy is back surgery that includes the surgical removal of all or part of the laminae (sections of the vertebrae that surround the spinal cord). This surgery is performed to gain access to the spinal cord to remove tumors, treat injuries to the spine, relieve pressure on a nerve, or to implant, revise or reposition a catheter to administer medication using an external pump.
Spinal fusion is surgery to correct problems in the spinal bones (vertebrae). The surgery stabilizes the back by permanently placing certain bones in the spine together. Fusing means two bones are permanently placed together so that movement between them can no longer occur. Spinal fusion is usually done along with other surgical procedures of the spine, such as a diskectomy.
Spinal microdiskectomy is surgery to remove disk fragments from a herniated disk , usually in the lower back (lumbar area). Unlike lumbar spine surgery that requires a surgical cut about 2 to 5 inches long, microdiskectomy is less invasive, and done using a very small surgical cut about 1 to 1 ½ inches long.
