Vertebral column is one of the most frequent sites that metastatic malignant tumors are seen. Primary spinal tumors and metastatic tumors decrease the resistance of vertebral column and results in progressive painful spinal deformities. İn this study a sum of 9 patients with 2 primary vertebral tumors, 5 metastatic tumors and 2 me-dulla spinalis originated tumors were evaluated. Five patients were female and 4 were male. Seven patients had pathological fractures while and the other two patients with medulla spinalis tumor had instability because of face-tectomy and complete laminectomy. Posterior instrumentation was performed in 6 (CDI: 1, Hartshill: 1, TSRH: 4) patients and 3 had anterior instrumentation (AO-CLP: 1, Kaneda: Z-piate: 1). The mean sagittal index which was 28.3° was corrected by 59.9%. Physiological sagittal contours were provided in al patients and their functional ca-pacities were significantly increased. İn light of these findings it is thought that posterior and anterior instrumentation is very important in the treatment of painfull instabilities to provide a functional life without pain in primary or metastatic spinal tumors.
