Elbow fat pads with new signs and extended differential diagnosis.

Murphy WA, Siegel MJ.

Although fat pad signs are classically associated with fracture, there are many nontraumatic disease processes which lead to positive fat pad signs. Any intraarticular fluid or tissue accumulation may result in an abnormal posterior fat pad. A "paradoxical" positive posterior fat pad sign may occur in some instances of extraarticular disease. An extended differential diagnosis is presented.
