Case Report: Here, we describe a surgical procedure using the Masquelet technique for the biological reconstruction of a huge subtrochanteric bone defect following failed pasteurized autologous bone grafting for a conventional chondrosarcoma of the proximal femoral metaphysis with a subtrochanteric pathological fracture. The patient, a 43-year-old Japanese male, was able to walk without a cane or a brace at 15 months after the final operation (International Society of Limb Salvage score, 86.7%). Conclusion: This procedure should be considered as one of the reconstruction options following the wide resection of malignant bone tumors located in the metaphysis. %U https://iv.iiarjournals.org/content/invivo/34/6/3495.full.pdf
