Lateral condyle fracture

Case contributed by Frank Gaillard
x-ray

On the lateral, there is clearly a fracture.  The capitellum is posteriorly displaced.

However, on the AP film, there is a small fragment of bone lateral to the distal humeral metaphysis and cortical irregularity medially.  

Case Discussion

There is a tiny ossific density adjacent to the lateral portion of the distal humeral metaphysis. Between it and a cortical irregularity in the intercondylar region, there is a fracture line. This is a lateral humeral condylar fracture and there is dorsal displacement of the distal fracture fragment.
