Implication

Comparative histological analysis reveals deep nerve ingrowth along granulation tissue zones in painful lumbar discs, indicating a key structural driver of discogenic back pain.

Key Points

To investigate the histological features and patterns of nerve fiber innervation in painful lumbar intervertebral discs compared with aging and normal control discs.
Examined 19 lumbar intervertebral disc specimens from 17 patients undergoing posterior lumbar interbody fusion for discogenic back pain, along with 12 aging discs and 10 normal control discs.
Assessed histological changes and immunoreactivity for neurofilament (NF200) and neuropeptides, including substance P (SP) and vasoactive-intestinal peptide (VIP), across disc regions.
Painful discs uniquely demonstrated a continuous zone of vascularized granulation tissue extending from the nucleus pulposus to the outer annulus fibrosus along tear edges.
Nerve fibers immunoreactive for SP, NF200, and VIP penetrated significantly deeper into the annulus fibrosus and nucleus pulposus of painful discs compared to controls, primarily tracking the granulation tissue zones.
