Internal (ie medial) epicondyle Conclusions: Traditional teaching that the AHL touches the capitellum on a lateral radiograph of a normal elbow in a child is correct, so if the AHL does not touch the capitellum it is appropriate to look for pathology.

Malalignment indicates a fracture - in most cases, posterior displacement of the capitellum in a supracondylar fracture. The avulsed medial epicondyl was found within the joint and repositioned and fixated with K-wires. They are extrasynovial but intracapsular. Treatment can be nonoperative or operative depending on the degree of angulation, translation and displacement. The coronal alignment of her elbows in extension is symmetric.
