Abstract
We report an unusual case of osteonecrosis of the femoral head associated with recurrent myopathy and bone abnormalities in a two-year-old girl, in whom symptoms occurred after a ten-day course of oral betamethasone for infectious wheezy bronchitis, and eventually recurred and were worsened by topical treatment; a hypersensitivity to glucocorticoids is hypothesised.
