Metastatic bone tumors were treated by reimplantation of the resected bone after autoclaving, with filling of the defects caused by tumor resection using fresh autogenous bone grafts.Case 1. A 67-year-old woman with lung cancer had a lytic lesion in the right lesser trochanter. At operation, the proximal quarter of the right femur was excised and autoclaved. A long-stem prosthesis was then inserted through the autoclaved bone and the remainder of the femur. She was able to walk with a cane for 14 months after the operation until her death from metastatic brain tumor.Case 2. A 56-year-old man with a Grawitz tumor had a metastatic lesion in the diaphysis of the left femur. The lesion was resected, the bone autoclaved, and then returned to its bed. A Küntcher nail was used for internal fixation.Case 3. A 37-year-old woman with breastt cancer had a metastatic tumor in the left supra-acetabular ilium. She was treated with an autoclaved bone graft to the ilium and THR was also performed for reconstruction.The mean follow-up period was 11 months. All patients were able to walk with canes, and had no infection or local recurrence. Several authors have reported on the advantages of autoclaved bone grafts for treating primary bone tumors.Our results suggest that autoclaved bone grafts are an attractive limb salvage procedure for metastatic as well as primary bone tumors.
