A fat pad is a collection of fat tissue adjacent to the elbow joint capsule, found both anteriorly and posteriorly. These fat pads can become displaced by an intra-articular effusion such as a hemarthrosis. A small, lucent anterior fat pad lying anterior to the distal humerus can be normal.

X-elbow - Startradiology

The elbow joint has both anterior and posterior fat tissue, the so-called fat pads. These pads are extrasynovial but are within the articular capsule. In many cases, the anterior fat pad is seen as a thin straight lucent (= black) line at the front of the distal humerus, this is a normal finding (fig. 5).

An abnormal anterior fat pad is described as a "sail sign" because it is unusually prominent and bows outward to form a triangular shape. After trauma, blood can accumulate in the intraarticular space and push the fat pad anteriorly; a positive sail sign in the setting of trauma is a reliable indication of an intraarticular fracture - even if no fracture line can be identified.

Fat Pads. On a normal elbow x-ray, only a small stripe of an anterior fat pad should be visible. No posterior fat pad should be seen. Injuries around the joint can produce a joint effusion which will displace the fat pads making them more visible. The anterior fat pad protrudes more and looks pointy; this is what is recognized as the sail sign.
