A 6-year-old girl presents to the emergency department (ED) with severe right elbow pain and deformity after a fall from the monkey bars 2 hours earlier. On physical examination, the patient's skin is intact, and she can move her fingers and wrist but cannot move the elbow. Her right hand is pink and warm, but no palpable radial or ulnar pulses are present. Radiographs are taken in the ED (Figures 1 and 2).
