Fat pad sign - Wikipedia

The fat pad sign, also known as the sail sign, is a potential finding on elbow radiography which suggests a fracture of one or more bones at the elbow. It is may indicate an occult fracture that is not directly visible. Its name derives from the fact that it has the shape of a spinnaker (sail). It is caused by displacement of the fat pad around the elbow joint.

The radiological diagnosis of post-traumatic effusion of ...

The 'displaced fat pad' sign indicating an elbow effusion is usually clearly visible, whereas the radiological appearance of bony injury is sometimes difficult to interpret, especially in children. In an injured elbow where the joint capsule may reasonably be presumed to be intact, the absence of evidence of effusion is a reliable indication ...

Fractures and dislocations of the elbow - ScienceDirect

The fat pad sign was first described by Norell11 in 1954. A thin layer of fat overlies both the anterior and posterior aspects of the elbow joint capsule. The posterior fat pad lies in the shallow intercondylar depression on the pos- terior surface of the humus and therefore is invisible on the normal lateral radiograph.

Rapid screening for the posterior fat pad sign in ...

Children with elbow injuries frequently present to the emergency department for evaluation. Fractures of the elbow are sometimes not visualized on plain radiographs and the only sign of an occult fracture is an elevated posterior fat pad that normally sits within the olecranon fossa. The elevated posterior fat pad sign is highly sensitive and its absence likely rules out fractures of the …

Posterior fat pad sign (elbow) | Radiology Reference ...

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 Fat Pads with New Signs and Extended Differential ...

Although fat pad signs are classically associated with fracture, there are many nontraumatic disease processes which lead to positive fat pad signs. Any intraarticular fluid or tissue accumulation may result in an abnormal posterior fat pad. A "paradoxical" positive posterior fat pad sign may occur in some instances of extraarticular disease.

US of the Elbow: Indications, Technique, Normal Anatomy ...

Intracapsular extrasynovial elbow fat pads are found between the hypoechoic synovial lining and hyperechoic linear fibrous capsule within the fossae. They are hyperechoic and triangular and are displaced with distention of the joint (4,5). A small amount of normal fluid may be seen between the anterior fat pad and humerus .

Ultrasonic demonstration of the elbow fat pads - ScienceDirect

Ultrasonic demonstration of the elbow fat pads. Elevation of the fat pads around the elbow joint is a well recognised radiological sign of a joint effusion which may be due to trauma or other inflammatory process. There are occasions when plain radiographs fail to demonstrate this sign. A case is reported in which elevation of the posterior fat ...

Lipohemarthrosis of the Elbow Joint | Radiology

Little fat accumulated in the anterior compartment of the joint can be demonstrated by horizontal-beam technique and lipohemarthrosis may conceivably be observed before posterior fat pad is displaced dorsally. With horizontal-beam technique, the patient is more comfortable and it seems unnecessary to irradiate the other elbow.

Positioning Test 12 (Elbow) -- [Fat Pads] Flashcards | Quizlet

only the anterior and supinator fat pads are visible, and the posterior fat pad is depressed within the olecranon fossa. The fat pads become significantly radiographically when an elbow injury causes effusion and displaces the fat pads or alters their shape.

An ultrasonographic result positive for fracture at the elbow was defined as the pediatric emergency physician's determination of an elevated posterior fat pad or lipohemarthrosis of the posterior fat pad. All patients received an elbow radiograph in the ED and clinical follow-up.

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. US findings were ...

Radiographic Evaluation of Common Pediatric Elbow Injuries

The fat pad sign is indicative of intraarticular elbow pathology even when a fracture is not apparent on standard elbow radiographs. 6 The fat pad, or sail sign, is caused by an intra-articular elbow effusion or hemarthrosis either anteriorly or posteriorly on lateral radiographs of the elbow.

AB - Objective: The aim of this study was to determine whether elbow ultrasound findings of the posterior fat pad (PFP) are present in patients with diagnosis of radial head subluxation (RHS). Methods: This was a prospective study of children presenting to an urban pediatric emergency department diagnosed clinically with RHS.

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.".

On a deeper plane, the outline of the posterior humeral cortex and the olecranon process can be seen. The humerus presents a posterior fossa that houses the olecranon during elbow extension.

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 ...
