Defect Reconstruction Post En Bloc Excision of Aggressive Giant Cell Tumor of the Distal Radius: A Report on Two Cases

Résumé

Giant cell tumor (GCT) though benign, represents a locally aggressive neoplasm characterized by proliferation of mononuclear cells, bone destruction and a high rate of recurrence. Management of aggressive GCT of the distal radius and reconstruction of resultant defect after excision remains a challenge. This is a report on two cases presenting with aggressive GCT of the distal radius with bone destruction and cortical breach of the distal radius. Both cases required an enbloc excision of the distal radius with a tumor free margin of 3cm, and subsequent reconstruction of the defect with a non-vascularized fibula graft and radiocarpal arthrodesis using a T-plate. Union was achieved in both cases. There were no reported infections, fractures or recurrence within the follow up period. Defect reconstruction of the distal radius following enbloc excision of the distal radius leads to satisfactory outcomes.
