Pediatric Elbow Fat Pad Sign

Emergency Department Elbow injury in children (fat pad sign)

A fat pad sign is when the normal pad of fat that sits around the bones in the elbow becomes raised up. This is usually due to swelling in that part of the elbow. This can be caused by damage to the ligaments in the elbow, or sometimes by a small fracture (break) to one of the elbow bones that can’t be seen on an X-ray. The reason it can’t ...

Fat pad sign - Wikipedia

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.

Other angles may tempt the posterior fat pad to emerge from the olecranon fossa, mimicking the fat pad sign. Therefore, in a noninjured, correctly positioned lateral elbow, the posterior fat pad should not be visible because it is hidden within the olecranon fossa. If the fat pad is evident, further study may be warranted to investi-gate injury.
