Positive Posterior Fat Pad. A lateral radiograph of the elbow shows a crescentric lucency projecting posterior to the distal humerus (white arrow) representing fat which has been displaced by an elbow joint effusion. Such effusions are frequently secondary to trauma and a subtle fracture of the neck of the radius is present (red arrow).

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.
