Aneurysmal bone cysts in children.

We analysed local recurrences in young children with aneurysmal bone cysts. Nine were boys and five were girls, aged 10 years or less. The sites of the lesions were distributed as follows: five femurs, four humerus, two tibia, one sacrum, one thoracic spine and one pubis. After intensive curettage, five patients underwent cementation and five patients bone grafting. Four patients underwent resection of the lesion. No patients received irradiation. One of the five patients who underwent cementation had a relapse and the lesion was controlled after the second curettage and cementation. One of the five patients who underwent bone grafting had a relapse, and he relapsed again after the second curettage and bone graft; finally his disease was controlled by resection of the lesion and bone grafting. After 55 months (median) of follow-up, all patients were disease-free. The local recurrence rate of aneurysmal bone cysts in children was not high in this hospital.
