6 cases of aneurysmal bone cyst were reviewed clinically and radiologically. Different therapies, including curettage and block excision were employed. 3 patients were women and 3 were men. The diagnosis was based on X-ray imaging and histology. 2 cases required differential diagnosis for osteosarcoma and solitary bone cyst. We used an air-drill for curettage and then implanted an auto bone graft and hydroxyapatite or cement packing. There were no complications and no recurrence at the mean follow-up of 34.8 months.
