fat pad in elbow fracture

Accuracy of the sonographic fat pad sign for primary ...

An elevated dorsal fat pad accompanies intracapsular elbow fractures involving the distal humerus, including supracondylar and lateral condylar fractures, or the proximal ulna or radius. Lipohemarthrosis can be seen sonographically by identifying an echogenic joint effusion with or without fluid levels [ 16, 17 ].

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 …

Purpose: The purpose of this study was to evaluate the diagnostic accuracy of the sonographic fat pad sign (FPS) as a predictor for pediatric elbow fractures. Patients and methods: This is a prospective study of children under 14 years with suspected elbow fractures. All participants underwent at first ultrasonography focused on a FPS followed by standard elbow radiographs.

Patients who present with posterior elbow pain can be ascertained to numerous conditions such as olecranon stress fractures, loose bodies and thickened synovial fold. However, posterior fat pad impingement of elbow is uncommon as it is missed in the X-rays. The posterior fat pad is extrasynovial and invested bycapsular leaflets.

Fat pad sign - Wikipedia

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 ...

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

The anterior fat pad is located in the coronoid fossa. A narrow anterior fat pad is a normal finding on the lateral view. The anterior fat pad can be displaced up and out by fluid in the elbow joint, creating the "sail sign". This usually indicates a fracture in children in the setting of an injury. The posterior fat pad is located in the ...

Displacement of Fat Pads in Disease and Injury of the Elbow

Norell (9), in an excellent observation, has described fat pad displacement about the humeral fossae in the presence of fractures involving the elbow joint, although he erroneously described the fat as "extracapsular.". A survey of the American radiological and orthopedic literature fails to reveal any report of this "fat pad sign.".

Elevation of the anterior fat pad usually heralds the presence of an intra-articular fracture. In adults, this is usually a radial head fracture whereas in children, the commonest cause of a raised elbow fat pad is a supracondylar fracture . Where a fat pad is raised and no fracture is demonstrated, an occult fracture should be suspected.

THE PEDIATRIC ELBOW: A REVIEW OF FRACTURES

Normally, when the elbow is flexed to 90°, the anterior fat pad may be seen just anterior to the joint; the posterior fat pad is not seen because it is located in the intercondylar fossa. With joint distention, the fat pads are displaced away from the joint in the anterior aspect; the fat pad will be elevated away from the joint and the ...

These fat pads are slightly more radiolucent than the adjacent muscle tissues, making them visible on a properly positioned 90° later- al radiograph of the elbow. They appear as a single radiolucent density. (See Fig. 1-A1.) The anterior fat pad can be elevat- ed in a …

The posterior fat pad sign (PFPS) on the lateral elbow X-ray is useful in the diagnosis of a suspected nondisplaced fracture about the elbow after a subtle injury. However, the presence of a PFPS hallmarks a continuous posterior periosteum-posterior capsule of the distal humerus. This anatomic structure is crucial for the stable anatomic reduction of a …

There is no obvious anterior or posterior fat pad, and the radio-capitellar line is intact. The radial head and distal humerus appear fine, while there is an obvious proximal olecranon fracture. Use this systematic approach to the elbow radiograph to avoid missing occult fractures of the elbow.

Elbow ultrasound can assist in ruling out a supracondylar fracture, which is particularly helpful in the case of an equivocal x-ray but high clinical suspicion. Next time you encounter a pediatric elbow injury with negative x-rays in the ED, grab an ultrasound probe to evaluate for a fat pad sign and lipohemarthrosis.

The elbow anatomy is unusual because there are two collections of fatty tissue contained within the joint capsule (anterior and posterior fat pads) ().When the elbow is flexed to 90°, these fat pads lie nearly entirely within the coronoid and olecranon fossae of the distal humerus. On a properly performed lateral radiograph, the anterior fat pad may appear as a small lucent area …

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.
