title: A new treatment of aneurysmal bone cyst by endoscopic curettage without bone grafting.
abstract: Curettage and bone grafting are the accepted methods of treatment of aneurysmal bone cysts. Unfortunately, recurrence is common. We treated 4 patients with atypical aneurysmal bone cysts that lacked aneurysmal dilatation by endoscopic curettage without bone grafting. New bone formation and remodeling were observed in all patients. In the patients in whom the follow-up was longer than 30 months, there was no evidence of recurrence. Endoscopic curettage without bone grafting is a simple and effective treatment for aneurysmal bone cysts.
