Management of distal femur aneurysmal bone cyst in an adult by extended curettage with bone substitute and internal fixation: an illustrative case report

Abstract


Aneurysmal bone cysts (ABCs) are benign osteolytic vascular neoplasm characterised by several sponge like blood filled or serum filled non endothelialized spaces of various diameter. ABCs can present a diagnostic challenge, as they share several histological and radiographic characteristics with other aggressive lesions like giant cell tumors and malignant telangiectatic osteosarcomas. In this article, we present a case of 34-year gentleman with left distal femur aneurysmal bone cyst treated by extended curettage augmented with bone substitute and internal fixation. In ABC management, curettage is the treatment of choice inspite of high recurrence rate. This is because of early return to functional activities and less morbidity. En bloc excision results in a lower recurrence rate but more extensive reconstructive surgery is needed which is associated with higher morbidity
