posterior fat pads elbow

Step 2: Examine the fat pads - Queen's U

The posterior fat pad is located in the olecranon fossa on the lateral view. It should not be visible under normal circumstances. Fluid in the elbow joint can displace the fat pad up and out making it visible on the lateral view. If the posterior fat pad is visible, it suggests a fracture in the setting of an injury.

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).

When the posterior fat-pad sign is positive, the extension of the synovial capsule with the elbow in 90° of flexion displaces the fat pad superiorly and dorsally. A false-positive posterior fat-pad sign can occur with the elbow in extension and is caused by olecranon process displacement and posterior capsule laxity. A paradoxical positive

Facts. Normal: elbow fat pads are intracapsular but extrasynovial, they are visible anteriorly to the elbow joint but not posteriorly. Effusion: elevation of both anterior and posterior fat pads are seen on lateral x-ray. In an acute injury to the elbow, elevated posterior fat pad suggests the possibility of an intracapsular fracture.

Background: An elevated posterior fat pad visible on a lateral radiograph of a child's elbow following trauma is generally considered to be suggestive of an intracapsular fracture about the elbow. However, in previous studies, the prevalence of fracture in elbows with an elevated posterior fat pad and no other radiographic evidence of fracture has ranged from only 6 percent (two of thirty-one ...

Occult fractures, also known as "hairline" elbow fractures, may not be visible on initial X-rays, but clues to the diagnosis, especially the posterior fat pad, can be helpful in evaluation. When an occult fracture is suspected based on history and radiographic findings, the patient's elbow should be immobilized, not manipulated.

The presence of two fat pads in the elbow are also helpful in detecting pathology. The anterior fat pad is located just anterior to the distal humeral diaphysis and can be seen in a normal elbow series as a small line or triangular radiolucency. The posterior fat pad is usually not visible because it lies in the olecranon fossa.

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.
