[Resection of an aneurysmal bone cyst in the proximal humerus with a non-vascularized fibular graft. Case report].

An aneurysmal bone cyst is a benign lesion involving the marrow of long bones; it accounts for 6% of primary bone lesions and may occur as a secondary lesion with other benign or malignant bone tumors. We describe herein the case of a seven year-old female with an aneurysmal bone cyst which was diagnosed clinically, radiographically and with a CAT scan, and confirmed with histopathology. Resection was performed using the eggshell technique and a non-vascularized left fibular bone graft. The patient did well up to the fourth postoperative year, which is consistent with what has been reported in world literature.
