An injury resulting in an outward (valgus) stress on the elbow, such as falling on an outstretched hand causes an avulsion fracture of the<unk><unk> . The<unk><unk>  is often the final growth plate (ossification center) to ossify in the elbow. Growth plates are particularly vulnerable to injury compared to bone. Children can have an open<unk><unk>  growth plate until age 13–17 years old, thus making the<unk><unk>  more susceptible to injury.<unk><unk>  fractures are associated with a dislocation of the elbow in about 25% of cases.
