  • The Elbow

    Anterior and posterior fat pads are located within the coronoid and olecranon fossae respectively. An intra-articular fracture will cause leakage of blood and marrow into the joint to give a joint effusion. This displaces the fat pads away from the bone. The anterior fat pad is normally visible as a lucent line hugging the anterior humeral cortex.

    The fat pad sign, also known as the sail sign, is a potential finding on elbow radiography which suggests a fracture of one or more bones at the elbow. It is may indicate an occult fracture that is not directly visible. Its name derives from the fact that it has the shape of a spinnaker (sail). It is caused by displacement of the fat pad around the elbow joint.
