abstract="To provide some order in the discussion of brain injuries the classification of injuries as &quot;open&quot; or 'closed&quot; is used. The basic criterion is the involvement of the dura. If it is intact, the injury is a &quot;closed&quot; one even though the skull may be fractured. If the dura is penetrated it is an &quot;open&quot; injury. Only the mechanics of &quot;closed&quot; brain injuries will be discussed here.<p />",
