Typical procedure for malignant bone tumors at tibial diaphysis. a Image data of A-P and lateral X ray films showed a metastatic neoplasm from primary thyroid carcinoma to distal tibial diaphysis before surgery. The vague boundary of the bone defect demonstrated that the lesion might be malignant. b Preoperative MRI imaging film demonstrated the accurate location and involved range of the metastatic lesion. c The microwave generator and antenna were inserted into the tumor bulk and began to deliver electromagnetic energy into the tumor bone. d Tumor bone inside the tibial diaphysis was removed and bone graft cavity was prepared. e The allograft bone fragments were used to fill the bone defect and a prophylactic fixation with was conducted using molding steel plate. f Postoperative A-P X and lateral ray films demonstrated the tumor removal and tibia rebuilding
