The question
A 3-year-old is brought for a limp. The parents say that at 3 weeks of age he had a hot, swollen right hip that was treated with oral medicines from a local practitioner. X-ray now shows complete loss of the right femoral head with the neck riding high, outside the acetabulum. What is the most likely diagnosis?
