    Bij het elleboog gewricht is er zowel een anterieure als een posterieure vetweefsel, de zogenaamde fat pad. Deze fat pads zijn extra-synoviaal, maar bevinden zich wel in het gewrichtskapsel. In veel gevallen wordt de anterieure fat pad gezien als een dunne rechte lucente (= zwarte) lijn aan de voorzijde van de distale humerus, dit is een normale bevinding (fig. 5).

    A narrow anterior fat pad is a normal finding on the lateral view. The anterior fat pad can be displaced up and out by fluid in the elbow joint, creating the "sail sign". This usually indicates a fracture in children in the setting of an injury. The posterior fat pad is located in the olecranon fossa on the lateral view.

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.
