“…They are caused by high-pressure guns emitting jet streams at high pressures (exceeding hundreds of atmospheres); at these pressure levels, the injected material is forced through minimally distensible structures of the hand and fingers, spreading along the fascia, tendon sheath and neurovascular bundles with significant destructive consequences [1]. Rees first reported in 1937 that the gas detected in the soft tissues could develop secondary to high-pressure injection injuries [2]. Subsequently, it has been reported that this may be due to not only gases but also a variety of liquids such as pressurized paint, grease, diesel fuel, helium, carbon dioxide and nitrous oxide [3].…”
