Go completely out of anatomic alignment
What does it mean to reduce?
Go back to anatomic alignment
What does it mean to subluxate?

-probably 99%
Posterior
-electrocution, seizure, or intoxication

What is a very important principle to remember when dealing with articular surface injuries?
The surfaces must be made perfectly straight in order to heal correctly
