A new high-pressure injection injury of the hand.

A high-pressure injection injury to the hand followed an unusually benign course, probably because of the nature of the substances injected, Freon and isopropyl alcohol. This is in marked contrast to the usually devastating result of injection of paint, grease, or diesel fuel under pressure. This type of injury may be seen more frequently in the future since the two substances injected are used for the cleaning and maintenance of computers and computer parts.
