In recent years, surgical treatments have been applied to cases with intense pain due to bone metastases of a malignant tumor and to those with pathological bone fractures. In the present study, we examined the postoperative result of cases in which osteosyn thesis combined with bone cement was performed in our department for metastatic bone tumors, aiming at improvement in QOL. Subjects were three men and one woman with the mean age of 66 years, with metasttic bone tumors in long cavity bones for which osteosynthesis combined with bone cement was performed. The observation period varied from 2 months to 13 months with a mean of 5 months. The regions were the femur in two cases, tibia in one and humerus in one, and the primary foci were renal carcinoma in two, bladder cancer in one and malignant neurinoma in one. During surgery, the metastatic focus was curetted and the bone fixed with a plate or an intermedullary rod and reinforced bone cement. In regard to QOL, pain was relieved in all cases and the patients recovered to the ADL level before appearance of symptoms. In the aspect of surgical indication, this technique had little surgical invasion with satisfactory short-term postoperative results leading to a marked improvement in QOL.
