Recurrent GCT of Distal Femur Treated with Resection Arthrodesis with Non-Vascularized Bilateral Fibular Graft and A Custom-Made Interlock Nail

INTRODUCTION: Giant Cell Tumors commonly occur around the knee joint in the age group of 20-30 years. They are treated with intra-lesional curettage or local resection and limb reconstruction. Management of large bone defects after resection is a challenge and is of ten complicated with non-union of grafts, infection and delayed weight bearing. CASE PRESENTATION: A 37-year-old male presented with an aggressive recurrent giant cell tumor of the distal femur. He was and was diagnosed with a GCT of the left distal femur 2 years ago for which he was treated with an intralesional curettage and Poly methylmetacrylate implantation. A resection arthrodesis using a bilateral non-vascularised intramedullary fibular graft and a custom made intramedullary nail was performed. The follow-up radiographs showed union at graft-host junction and hypertrophy of the grafted fibula at 2 years post surgery. CONCLUSION: Non-vascularised fibular graft is an effective alternative for resection arthrodesis with the advantages of a simpler and shorter surgical procedure and without the needs for a microsurgical setup.
