X-ray Vision - Shoulders and Elbows - Taming the SRU

 · Radial head and neck fractures are the most common elbow fractures encountered in adults and can be classified by the Mason-Johnston system (14). These fractures can be very subtle and are sometimes missed; on occasion, a displaced anterior fat pad may be the only radiographic sign of a radial head/neck fracture.

The Fat Pad Sign1 - RPH Doctor

 · A false-negative fat pad sign may occur if there is poor positioning, extracapsular abnormal-ity, or capsular rupture. The posterior fat pad may usually be visualized with the elbow in extension (3). With the triceps relaxed, the posterior capsule is lax, and the olecranon process displaces the fat pad from the olecranon fossa. Normal displace-

Elbow - Radiology Key

 · The elbow ( Figures 3.1 a–c and 3.2 a,b) is a hinge joint that consists of three articulations within a single synovial space. The lower end of the humerus is composed of two different shapes. On the lateral side, a partly spherical contour (capitellum) articulates with the concave articular surface of the head of the radius.

 · Fat Pads. On a normal elbow x-ray, only a small stripe of an anterior fat pad should be visible. No posterior fat pad should be seen. Injuries around the joint can produce a joint effusion which will displace the fat pads making them more visible. The anterior fat pad protrudes more and looks pointy; this is what is recognized as the sail sign.
