Study Notes
Seddon-Sunderland Classification of Nerve Injury
-
Seddon Classification focuses on the severity of nerve injuries:
- Neuropraxia: Nerve conduction block without structural damage; axon is intact.
- Axonotmesis: Axon and endoneurium are damaged; perineurium remains intact.
- Neurotmesis: Complete nerve transection; all structures including axon, endoneurium, and perineurium are disrupted.
-
Key Types in Seddon Classification:
- C: Refers to Axonotmesis (axon damaged, endoneurium intact).
- A: Denotes Neuropraxia (focal demyelination).
- D: Addresses Neurotmesis (complete nerve transection).
Sunderland Classification
-
Sunderland Classification builds on Seddon by categorizing nerve injuries into grades:
- Grade 1: Neuropraxia; focal segmental demyelination with intact structure.
- Grade 2: Axon injured, endoneurium intact.
- Grade 3: Axon and endoneurium damaged; perineurium intact.
- Grade 4: Axon, endoneurium, and perineurium damaged; epineurium intact.
- Grade 5: Complete nerve transection with all components involved.
-
Key Types in Sunderland Classification:
- E: Corresponds to Grade 5 (complete nerve transection).
- D: Relates to Grade 4 (axon, endoneurium, and perineurium damaged).
- C: Represents Grade 3 (axon and endoneurium damaged).
- B: Aligns with Grade 2 (axon damaged, endoneurium intact).
- A: Indicates Grade 1 (focal segmental demyelination).
