Abstract
We report a case of multiple bone metastases from breast cancer with femoral head replacement due to pathological fracture of the femoral head 81 days after injection of strontium chloride (Sr-89), radiopharmaceutical for bone pain palliation. Before replacement, the external radiation dose was estimated, and careful attention was paid to reducing the radiation from the exposed bones containing Sr-89 during the surgery. The calculated dose and measured dose with the portable dose rate meter were far below the exposure limits. We think this report will be informative for future occasions of such plastic surgeries.
