L7: Disc Prolapse Flashcards
Types of Disc Prolapse
- Acc to Timeframe
- Acute & Gradual
Types of Disc Prolapse
- Acute
Types of Disc Prolapse
- Gradual
Types of Disc Prolapse
- Type of protrueded Material
- The protruded material in both acute & gradual being first soft, then become fibrotic and later calcified and bony hard.
Direction of Protrusion in Disc Prolapse
Site of Cervical Disc Prolapse
- C5-6, C6-7 discs.
- C5-6-disc compress C6 root
Direction of Protrusion in Cervical Disc Prolapse
- Lateral: in intravertebral foramen → root pain (brachialgia) Due to pressure by disc, osteophytes, ischemia & later fibrosis of root sheath.
- Posterior → cord (by direct pressure or ischemia) → quadriplegia.

Def of Sciatica
Pain along distribution of sciatic nerve, commonly d2 Lumbar Disc Prolapse
Anatomy of Sciatic Nerve
Sciatic nerve derived from L4-5, S1,2,3 segments
Direction in Lumbar Disc Prolapse
Etiology of Sciatica
A. Degenerative changes
B. Trauma usually bending to lift heavy objects
