[The authors respond:]
We thank Pierre Juéry for his interest in our report on avascular necrosis of the femoral heads.1 We would like to clarify the chronology of events: the patient's symptoms appeared 8 months after the corticosteroid injection; the MRI scan was done 5 months after the onset of the symptoms or in other words 13 months after the corticosteroid injection. Because the time to symptom onset fits with other reports in the literature, and we excluded all other known causes of avascular necrosis of the hip, it is our opinion that all patients should be warned about the risk associated with even a low dose of corticosteroids.
