Primary lesions were kidney in three cases, lung in two, breast and esophagus in each one case. Levels of metastasis were cervical in one case, thoracic in four and lumbosacral in two cases. All suffered from pain and 5 cases were paralized. Several operative methods were done. Spinal instrumentation with bone cement was performed in 6 cases. Improvemnt of paralysis and pain were studied. All cases showed improvement but duration was variable in cases. Indication and purpose of operative treatment were discussed.
