Radial head subluxation is the most common upper extremity injury of children younger than 6 years of age, with the peak incidence occurring among toddlers. The diagnosis is clinical and is based on classic posturing of an arm held limply at the side in slight flexion of the elbow and pronation of the forearm without physical evidence of trauma. Radiographs usually are unnecessary. Pronation of the wrist is the preferred method for reducing radial head subluxation, although supination followed by flexion also is effective. Most children who experience radial head subluxation regain normal function within 10 to 15 minutes of successful reduction.
