The nerve supply of the lumbar intervertebral disc.

Edgar M.A.

A review of the literature that explores the innervation of the lumbar intervertebral disc.It contains a clarification of the sensory pathways and explores the theory that the disc is mainly supplied by the sympathetic nervous system. The author discussed the findings of sensory nerve endings in a degenerative lumbar disc which penetrate  into the nucleus pulposus, normally insensitive in a standard disc.

The author considers the growing evidence to support a 'visceral pain' hypothesis for the nature and mechanism of discogenic pain. He suggests this mechanism is open to 'peripheral sensitisation' and possibly 'central sensitisation' as a potential cause of chronic back pain.
