A 3-Year-Old Boy with Trouble Walking Due to Right Foot Pain

The patient is a 3-year-old boy whose mother brings him to your urgent care center, reporting that her son has to be coaxed to stand and to walk because he says his foot hurts. She is not aware of any injury, or possible mechanism of injury. You observe that the boy is limping.            

Review the x-ray taken and consider what your diagnosis and next steps would be.
