Avulsion on a hippopotamus In medicine, an avulsion is an<unk>  in which a body structure is torn off by either trauma or surgery (from the Latin avellere, meaning "to tear off"). The term most commonly refers to a surface trauma where all layers of the skin have been torn away, exposing the underlying structures (i.e., subcutaneous tissue, muscle, tendons, or bone). This is similar to an abrasion but more severe, as body parts such as an eyelid or an ear can be partially or fully detached from the body.
