Spinal cord tracts

Dorsal columns
- Proprioception, vibration
- Decussation at medulla
Corticospinal Tract
- Voluntary motor
  - Upper extremity fibers more central, lower extremity fibers more lateral
- Decussation at medulla
Spinothalamic
- Crude touch, pressure, pain, temperature
- Decussates 1-2 levels above entry point to spinal cord

Higher lesions are a/w spinal shock and autonomic dysfunction
Priapism implies a complete injury
Sacral sparing excludes complete transection
- Can only be assessed AFTER spinal shock has ended, ie after return or bulbocavernosus/cremasteric reflexes
- Sacral sparing manifests as intact great toe flexor function, perianal sensation, rectal motor function

-*Etiology
-**Transverse hemisection of spinal cord
-**Unilateral cord compression
-*Symptoms
-**Ipsilateral spastic paresis
-**Ipsilateral loss of proprioception, vibration but contralateral loss of pain, temperature (ie 'sensory dissociation')
-*Good prognosis
