What's the difference between avulsion and contusion?

Avulsion


Definition:

  • (n.) A tearing asunder; a forcible separation.
  • (n.) A fragment torn off.
  • (n.) The sudden removal of lands or soil from the estate of one man to that of another by an inundation or a current, or by a sudden change in the course of a river by which a part of the estate of one man is cut off and joined to the estate of another.

Contusion


Definition:

  • (n.) The act or process of beating, bruising, or pounding; the state of being beaten or bruised.
