What is a fat pad in the elbow?

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).

Elbow fractures may not be evident on an x-ray, but secondary signs, such as a fat pad elevated by bleeding, may indicate that there is a fracture. An anterior fat pad is often normal, but if elevated it is abnormal. A posterior fat pad seen on a lateral x-ray of the elbow is always abnormal. If a posterior fat pad is identified without a ...

An isolated fat pad sign (i.e. joint effusion without a visible fracture), commonly seen in acute elbow injury, is associated with occult fracture and treated as such. However, the clinical relevance of an isolated fat pad is unclear, thereby questioning the need for specialized follow-up. In this s …

The anterior fat pad located in the coronoid fossa may be seen in a normal lateral elbow radiograph as a line parallel to the distal humerus. The posterior fat pad, which is located in the much deeper olecranon fossa, is not visible on lateral images. Anterior and posterior fat pads are intra-articular but extrasynovial structures.

How to screen a paediatric elbow X-ray for injuries

Appearance of a posterior fat pad on lateral elbow X-rays may be the only clue to an elbow injury. Its presence should prompt the clinician to meticulously scrutinize the X-ray for a subtle 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 ...

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.

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.".

For many years, the fat pad sign has been used as an indication of an occult fracture. The posterior fat pad sign has been reported as a reliable sign of an elbow joint effusion [1,2,3, 5]. However, the presumed incidence of a fracture has varied widely in both the radiologic and orthopedic literature.

Regarding the wrist the "navicular fat stripe" and the "pronator quadratus sign" (PQS) have been described. Mac Ewan was first to characterize the pronator quadratus fat pad sign consisting of a radiolucent (fat containing) stripe which runs parallel to the pronator quadratus muscle covering the distal radius and ulnar (Figure 1)[1,2].

This prospective study demonstrated that the posterior fat pad sign was predictive of an occult fracture of the elbow following trauma in thirty-four of forty-five children who had no other evidence of fracture on anteroposterior, lateral, and oblique radiographs after the injury.

The authors obviously did not recognize this fracture, which casts ...

The fat pad was shaved off using 3.5 mm shaver and no impingement of soft-tissue was evident. An incidental finding of small foramen was found in the olecranon fossa(Fig. 3). It was found that the rent in the olecranon fossa got the fat pad locked into it, causing impingement on elbow extension.

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 elbow ...

In elbow effusion, the posterior fat pad is displaced dorsally and superiorly by the joint fluid. Thus, bone does not flank the posterior fat pad medially and/or laterally, and it becomes visible on the lateral radiograph (Figure 3). Effusion also displaces the anterior fat pad anteriorly and superiorly. The anterior fat pad, which is normally ...
