Is that a fracture or a growth plate?
Pediatric elbow x-rays are complicated to interpret due to the large number of ossification centers.
Elbow trauma is common in pediatrics.
Ossification centers of the elbow appear in a reliable chronologic pattern which aids in distinguising fractures from growth plates.
Note the age ranges are an estimate with great variability. For example, girls can develop these up to 2 years earlier than boys.
The numbers 1/3/5/7/9/11 correspond to the average age of development of each ossification center

Consider ordering films of both elbows to compare if in doubt.
How is this useful? If the trochlear center is present, but there is no medial epicondyle then you are most likely looking at a fx where the ossification center has been avulsed and displaced.
