Objective      To explore the surgical treatment strategies and the evaluation of the therapeutic efficacy for spine reconstruction after intraspinal tumor removal.       Methods      We retrospectively analyzed a series of 73 patients with intraspinal tumor who were treated surgically from January 2008 to June 2012. There were 39 males and 34 females with the average age of 32.7 years ranging from 16 to 68. Completely intradural tumors existed in 38 patients

and tumors in vertebral ca

nal in 35 patients. The patients with completely intradural tumors underwent en bloc laminectomy. The spinous process and lamina complex was replanted

in situ

and fixed by titanium plate after resection of spinal cord tumors．Other patients treated with pedicle screw internal fixation surgery.       Results      The operation time varied from 180 to 270 min

with an average of 210 min. The blood loss varied from 300 to 1 200 mL

with median volume of 660 mL. One patient who suffered from lipomyoma located at C

showed spinal dysfunction.  All patients were followed up for 6 to 39 months

during which no malunion

infection

spinal stenosis

displacement or collapse of the replanted tissues

or looseness or shift of internal fixation was observed．By comparing Flexion-extension radiographs

replantation of the spinous process and lamina complex and fixation with titanium plate in the resection of intraspinal tumors kept spinal mobility well. Pedicle screw fixation resulted in an ideal stability.       Conclusion      Surgical approach of resection of intraspinal tumor should be selected according to the location and whether the tumor causes destruction of the intervertebral joint stability. The completely intradural tumors should be treated by en bloc laminectomy

with spinous process and lamina complex replanted in situ and fixed by titanium plate after resection of intraspinal tumor. When the intervertebral joint stability is destroyed by tumors

the patients should be treated by pedicle screw fixation to restore the stability.
