====== Atlantooccipital dislocation clinical features ======

1. may be neurologically intact, therefore must be ruled out in any major trauma

2. bulbar-cervical dissociation 

3. may have lower cranial nerve deficits (as well as VI palsies) ± cervical cord injury

4. worsening neurologic deficit with the application of cervical traction: check lateral C-spine films
immediately after applying traction.
