Elbow Xray Fat Pad

  • Radiology In Ped Emerg Med, Vol 1, Case 12

    However, when the elbow joint capsule becomes distended (eg., hemarthrosis secondary to a fracture within the joint space), the anterior fat pad is displaced further anteriorly and superiorly to form an anterior "sail sign" or a more prominent lucency. c) The posterior fat pad normally lies over the olecranon fossa.

    In 1954, Norell described the 'fat pad sign' for the first time. This refers to the radiological visualization of the elbow fatty tissue. This is a prospective study with the aim of clarifying the relation between the presence of a positive fat pad sign on the lateral radiograph and the type of injury verified on MRI.

    Visible anterior fat pad - radiolucency anterior to the distal humerus, normally visible. Visible posterior fat pad - radiolucency posterior to the olecranon, normally hidden behind olecranon and thus presence indicates effusion Occult fracture. Sail sign - raised anterior fat pad due to effusion Occult fracture, usually of radial head.

    An AP view was taken of the forearm, but the top was cut off through the elbow. 1. Anterior fat pad: Not able to see it. 2. Posterior fat pad: Not able to see one. 3. Anterior humeral line: Not quite perfect. The anterior humeral line intersects the anterior third of the capitellum. This suggests that the capitellum is displaced posteriorly.

    The posterior fat pad sign is the visualization of a lucent crescent of fat located in the olecranon fossa on a true lateral view of an elbow joint with the elbow flexed at a right angle indicating an elbow joint effusion.. Normally, the posterior fat pad will not be seen in this view. In the setting of trauma, it suggests an occult non-displaced fracture. In children, a supracondylar fracture ...

    Elbow joint effusions. On the lateral view of the normal elbow without a joint effusion ( A and C ), the posterior fat pad is not apparent, whereas the anterior fat pad is visible but not elevated. In the presence of a joint effusion (hemarthrosis), the fat pads are displaced, and both the anterior and posterior fat pads become visible ( B and D ).

    On the lateral x-ray of the elbow, a joint effusion can be inferred when there is displacement of the anterior fat-pad or presence of the posterior fat pad. An elbow joint effusion without a visible fracture seen on radiographs can suggest an occult fracture and should prompt further evaluation.

    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).

    As previously mentioned, three intracapsular fat pads are present between the synovium of the elbow and the joint capsule. The anterior fat pad is a summation of the radial and coronoid fat pads, which are normally pressed into the shallow radial and coronoid fossae by the brachialis muscle during extension.
