Navicular avascular necrosis in juvenile idiopathic arthritis.

We present a case of a child in middle childhood (6-11 years) diagnosed with juvenile idiopathic arthritis (JIA) who developed glucocorticoid-induced avascular necrosis (AVN) of the navicular bone. Glucocorticoid-induced AVN in children, particularly of the navicular bone, is a rare but serious complication. Glucocorticoid therapy, often used in managing JIA, can disrupt the blood supply to developing bones, leading to AVN. Early recognition and intervention are crucial to prevent long-term morbidity. This case underscores the importance of minimising the duration of prolonged glucocorticoid use in children.
