Elbow fat pads with new signs and
extended differential diagnosis.
Murphy WA, Siegel
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.
