Supracondylar fracture

Case contributed by A.Prof Frank Gaillard

Presentation

Painful elbow following a fall

Patient Data

Age: 7 years
Gender: Female
X-ray

Elbow radiographs

AP and lateral radiographs of the elbow demonstrate a lucency across the distal humerus consistent with a supracondylar fracture. A line drawn along the anterior border of the humerus does not intersect the middle third of the capitellum, indicating that the fracture is somewhat posteriorly angulated. 

Annotated image

Anterior humeral line

A line drawn along the anterior broder of the distal humerus (green) should intersect the long axis of the capitellum (purple) in the mid third (area shaded light green).   

In the setting of a painful elbow following a fall, if this line does not intersect the green area, but rather the red area then a supracondylar fracture should be suspected.
