Endoscopic high-speed curettage and bone grafting of aneurysmal bone cyst of the lateral malleolus in a 9-year-old boy

Abstract

Background: Aneurysmal bone cysts (ABCs) are benign bone tumors that have marked osteolytic, expansive, and bleeding capability. The comprehensive excision of the pathological tissue combined with bone grafting of the cyst is the most successful therapeutic intervention. Case report: We report a case of an ABC of the lateral Malleolus in a 9-year-old boy. The bone cyst was treated effectively by excising the pathological tissue of the cyst using a high-speed endoscopic curettage combined with bone grafting of the cyst. Six months postoperatively, comprehensive healing of the ABC of the lateral malleolus was evident. In the final follow-up, five years postoperatively consolidation of the cyst without relapse was obvious. Conclusion: Endoscopic high-speed curettage, allowing an accurate, methodical, and aggressive resection of the cyst's pathological tissue, is significant for the successful and comprehensive healing of the ABCs. For the effective endoscopic cyst curettage, occasionally radiographic assistance is necessary to avoid growth plate damage.
