The posterior fat pad sign in association with occult ...

This prospective study demonstrated that the posterior fat pad sign was predictive of an occult fracture of the elbow following trauma in thirty-four of forty-five children who had no other evidence of fracture on anteroposterior, lateral, and oblique radiographs after the injury.

An injury in a child's elbow | The BMJ

 · In a displaced fracture, the diagnosis is usually obvious on plane radiographs. If, however, the fracture is undisplaced, the diagnosis is often more difficult, and the "posterior fat pad" may be of diagnostic value. The fat pads are small masses of fat within the fibres of the joint capsule and are therefore intracapsular …
