Question
A 12-month-old boy has refused to move his right lower extremity for the past 24 hours; however, his parents deny any history of trauma. He has a rectal temperature of 102.2 degree F (39 degree C). Examination reveals marked guarding during attempted passive motion of the right hip; however, motion of the lumbar spine and right knee is tolerated. Laboratory studies show a peripheral WBC count of 15,500/mm3 (normal 3,500 to 10,500/mm3) and an erythrocyte sedimentation rate of 60 mm/hr (normal up to 20 mm/hr). A pelvic radiograph is normal. Management should now consist
1- radiographs of the spine
2- radiographs of both lower extremities
3- blood cultures
4- needle aspiration of the right hip
5- pelvic MRI
