Pediatric Radial Head Fractures Special Considerations and .

The pediatric elbow joint is distinct because of its six ossification centers and whether or not they appear on xray depends on the ages at which they ossify and fuse. The presence of a mechanical block can be the difference between surgery and conservative management for intraarticular radial head fractures.

Note the raised anterior and posterior fat pads on the lateral view. And an extra bonus point to those who spotted the subtle radial neck fracture.

PEM Pearls Ultrasound for Diagnosing Occult Supracondylar .

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

Fat Pads. On a normal elbow xray only a small stripe of an anterior fat pad should be visible. No posterior fat pad should be seen.

The anterior fat pad protrudes more and looks pointy this is what is recognized as the sail sign.

Positive fat pad sign 2 Any elbow joint distention either hemorrhagic inflammatory or traumatic gives rise to a positive fat pad sign. If a positive fat pad sign is not present in a child significant intraarticular injury is unlikely. A visible fat pad sign without the demonstration of a fracture should be regarded as an occult fracture.

Rapid screening for the posterior fat pad sign in suspected .

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.
