Seddon's classification

Jump to: navigation, search

Seddon's classification is a scheme for describing nerve injury.

  1. Neurapraxia -- pressure on the affected nerve with no loss of continuity.
  2. Axonotmesis -- neural tube intact, but axons are disrupted. These nerves are likely to recover.
  3. Neurotmesis -- the neural tube is severed. These injuries are likely permanent without repair, and will likely only achieve partial recovery at best.
