Lateral humeral condylar fracture

Dr Jeremy Jones et al.

Lateral humeral condyle fractures are relatively common elbow fractures that predominantly occur in children. 

They represent ~12.5% (range 5-20%) of elbow fractures in children and are the second most common paediatric elbow fracture after supracondylar fractures.

They occur in school-age children, with a peak at 6 years 4.

These occur either after fall onto outstretched hand, causing radial head to impact the capitellum, or as an extensor carpi radialis longus and brevis avulsion injury after varus stress on a supinated forearm 4,5
