Treatment surgical (e.g. discectomy)

Degenerative disc disease, abbreviated DDD, is a common ditzel, typically generated in the course of a discectomy operation.

Sciatica,[1] vertebral disc and discectomy redirect here.

General

  • Herniated disc - causes back pain.
  • May result in cauda equina syndrome.
  • Composed of fibrous cartilage.[2]

Microscopic

Features:

  • Benign fibrous tissue.
  • Nests of chondrocytes (as in immature cartilage).
  • +/-Synovium with or without proliferation.[3]
  • +/-Neovascularization of disc material.[3]
  • Hemosiderin deposits (trauma or previous surgery).

Disc Material (L4-L5 Disc), Excision:
- Consistent with disc material (gross only).
Disc Material (Left L5-S1 Disc), Excision:
- Consistent with disc material (gross only).

Note:

  • May be gross only specimens; a minority of institutions handle these specimens this way.[6]
    • It is suggested that gross only specimens should have no history or suspicion of malignancy - based on the surgical note, available pathology and imaging.
