Laminectomy is a ıvidely used approach to the dorsal spinal tumors. However, there are objections to perform-ing without a stabilizing procedure. We revievved our patients who had been undergone a laminectomy procedure for dorsal spinal tumors during the last ten years. Except one, we did not need any stabilizing technique in thirtyone cases. Postoperatively, no instability was observed on radiological examinations. So instability shouid not be con-sidered as a disadvantage for laminectomy performed in normal limits.
