[Surgical treatment of spinal tumors: a report of 30 cases]

With the advance of spinal surgery in the last decade, surgical treatment of spinal tumors has been no longer limited to sole laminectomy. The principles of surgical treatment of spinal tumors include: (1) anterior approach for the anterior lesion and posterior approach for the posterior lesion, (2) combined anterior and posterior approach for extensive lesions and (3) internal fixation for spinal stability. 30 cases of spinal tumors were treated on the basis of the above guiding principles and 83.3% (25 of 30 cases) showed excellent or good outcomes.
