Aneurysmal bone cyst is a rare benign bone tumor usually treated by surgery, which may in turn result in poor functional outcome and recurrence. This study aims to report a series of cases of primary ABC treated with a single dose of calcitonin and methylprednisolone injection. Six patients treated with a single-dose combination of calcitonin (200 UI) and methylprednisolone (120 mg) at a single institution from January 2011 to December 2013 were clinically and radiologically evaluated. After the follow-up period, all patients presented cyst healing. The mean time to healing was 2.8 months. The final mean overall functional score rating was 89.0%. We conclude that intralesional calcitonin and methylprednisolone injection results in aneurysmal bone cyst healing with good functional outcomes and thus can be an effective treatment method.
