A Case of Proximal Radius Aneurysmal Bone Cyst Treated with Curettage and Inlay Fibular Graft

(BACKGROUND) Aneurysmal bone cyst, abbreviated ABC, is an osteolytic bone neoplasm characterized by several sponge-like blood or serum filled, generally non-endothelialized spaces of various diameters. A 13 year old male child presented with pain and deformity of forearm, diagnosed to be Aneurysmal Bone Cyst of proximal radius with functional impairment and movement restriction of elbow and forearm. (METHODS AND MATERIALS) Functional status on first visit-Mayo Elbow Performance Score=55. After non-invasive investigations, biopsy was done and diagnosis was confirmed as Aneurysmal bone cyst. There were many options but we went for curettage and fibular grafting. Pre-operatively we calculated the length of fibula required. We harvested the fibula by percutaneous subperiosteal resection and after curettage of the tumour, fixed the fibula with proximal and distal part of radius by k-wire which was removed after 3 weeks and proper rehabilitation was given. (RESULTS) By 14 months there were regression of tumor, complete fibular graft incorporation with the radius, regrowth of fibula at the donor site, functional improvement and increase in joint movement. By that time the Mayo Elbow Performance Score=100. (CONCLUSION) Even large osteolytic cavity may be treated with Autogenous Inlay Bone Grafting after satisfactory Curettage with successful post-op Functional Recovery.
