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.
尽管脂肪垫征通常与骨折相关，但有许多非创伤性疾病过程也会导致脂肪垫征阳性。任何关节内液体或组织积聚都可能导致后脂肪垫异常。在某些关节外疾病情况下可能会出现“矛盾性”后脂肪垫征阳性。本文给出了一个扩展的鉴别诊断。
