OBJECTIVE: Both primary and metastatic tumor of spine can influence spinal stability, spinal cord and nerves. The principles of dealing spinal tumor are resection of tumor decompression on spinal cord and reconstruction of spinal stability. METHODS: Since Aug. 1993 to Oct. 1996, 15 cases with spinal tumor were treated, including 4 primary spinal tumor and 11 metastatic tumor. Tumor foci were mainly in thoracic and lumbar spine. Graded by Frankel classification of spinal injuries, there were 1 case of grade A, 1 of grade B, 3 of grade C, 5 of grade D and 5 of grade E. Tumors of upper lumbar spine and thoracic spine were resected through anterior approach. Posterior approach also was adopted once posterior column was affected. Tumors of lower lumbar spine were resected by two-staged operation: firstly, operation through posterior approach to reconstruct spinal stability: secondly, operation through anterior approach. After resection of tumor, the spines were fixed by Kaneda instrument, Steffee plate or Kirschner pins. To fuse the spine, bone grafting was used in benign tumor and bone cement used in malignant tumor. RESULTS: Except one patient died from arrest of bone marrow, the others were followed up for 3 to 20 months. Postoperatively, 11 patients could sit up on one foot with the help of body supporter, and 9 patients could walk in two weeks under careful monitoring. There was no exacerbation of symptom and failure of fixation. The function of spinal cord was improved: 1 case from grade B to grade E, 1 from A to C, 2 from C to E and 4 from D to E. CONCLUSION: The spine can be reconstructed for weight bearing early by internal fixation. The symptom can be relieved and the nervous function can be improved by resection of tumor and decompression.
