title: [Surgical treatment for the intradural extramedullary tumor in the spinal canal].
abstract: OBJECTIVE
  To study the clinical characteristics of the intradural extramedullary tumor in the spinal canal, as well as the application of internal fixation technique to restore the spinal stability in the surgical treatment of intradural extramedullary tumor in the spinal canal through posterior approach.
  
  
  METHODS
  Among 24 patients receiving the tumor resection through posterior approach, 14 patients were male and 10 patients were female, ranging in age from 12 to 68 years, with an average of 40 years. Fourteen patients were treated with internal fixation and autogenous bone graft after tumor resection, and other 10 patients without internal fixation and autogenous bone graft.
  
  
  RESULTS
  All the patients underwent one-stage resection of the tumor. During the follow-up period ranged from 6 months to 3 years (average 22 months), no recurrence of the tumor was found and the injury of spine cord did not aggravate, no vascular or nerve-root injury after the operation. The Frankle grades were improved by 1 to 3 degrees. Bone fusion formed at the corresponding bone grafted place. And there was no instrument broken or loosening.
  
  
  CONCLUSIONS
  After the intradural extramedullary tumor is resected, internal fixation and autogenous bone graft can restore the stability of spine.
