Lower Back Surgery
Spinal laminectomy, also known as spinal decompression, involves the removal of the lamina (usually on both sides) to increase the size of the spinal canal and relieve pressure on the spinal cord and nerve roots.
Rhizotomy, Cordotomy, or Dorsal Root Entry Zone Operation
Other surgical procedures that are used to relieve severe chronic lower back pain include:
- Rhizotomy, in which the nerve root closest to where it enters the spinal cord is cut to block nerve transmission and sensation from the area of the body experiencing pain
- Cordotomy, where bundles of nerve fibers on one or both sides of the spinal cord are intentionally severed to stop the transmission of pain signals to the brain
- Dorsal root entry zone operation, or DREZ, in which spinal neurons transmitting the pain are destroyed surgically.
