A 20-year-old male presents with a visibly deformed elbow and severe pain after falling on his outstretched arm during a skateboard accident. The forearm appears to be displaced posteriorly. What is the likely diagnosis and what are the next steps?
This scenario suggests a posterior elbow dislocation, which is commonly caused by a fall on an outstretched arm. The patient should be given pain relief, and an X-ray should be obtained to confirm the dislocation and to rule out any associated fractures. If no fractures are present, the elbow should be reduced as soon as possible, ideally under sedation or anesthesia.
