Typical procedure for malignant bone tumors at femoral diaphysis. a Image data of A-P X ray and MRI films demonstrated an osteosarcoma at femoral diaphysis before surgery. There were distinct signs of cortical bone destruction in the middle part of the right femoral shaft and visible soft tissue mass shadow in the anterolateral range of quadriceps femoris. b The incision demonstration from lateral thigh after skin degerming. c Dissect the tumor-bearing bone from surrounding normal tissues with safe margin and a heat-isolation pad was put between the tumor bone and surrounding normal tissues. d The microwave generator and antenna were inserted into the tumor bulk and began to deliver electromagnetic energy into the tumor bone. e Soft tumor mass and tumor bone inside the femoral diaphysis were removed and bone graft cavity was prepared. f The mixture materials of autologous fibular graft with allograft bone chips or bone cement were used for filling the cavity. g Restore the normal shape of the femoral diaphysis and give a prophylactic fixation. h Postoperative A-P X ray film showed the complete tumor removal and perfect bone transplantation
