The sinuvertebral nerve is a recurrent nerve that arises from the ventral ramus and re-enters the spinal canal through the intervertebral foramina to supply various meningeal and non-meningeal structures. Its intricate anatomy and connection to discogenic pain.
Research has shown that when nerve fibers come into contact with the nucleus pulposus, there is a decrease in spinal nerve root conduction velocities, nerve degeneration occurs , nerve discharge increases, intraneural capillary permeability rises , and inflammatory cells are attracted.
Further studies have identified nerve fibers penetrating tears in the anulus of degenerative discs through vascularized granulation tissue, which are believed to be the pathoanatomical cause of low back pain in individuals with degenerative disc disease.
The C1–C3 sinuvertebral nerves is now recognized as the primary cause of most cervicogenic headaches.
