Objective To explore the feasibility and clinical results of circumferential decompression and three column reconstruction through single-stage posterior transpedicular approach for spinal tumor treatment. Methods Totally

24 patients with spinal tumor underwent tumor resection and spinal reconstruc tion through single-stage posterior transpedicular approach. Preoperatively

according to the Frankel classification

12 patients were grade E

9 grade D

and 3 grade C. Anterior column was reconstructed with non-expandable titanium cages. Posterior segmental instrumentation was used to maintain the stability of spine in all cases. Anterior and posterolateral fusion was performed with autograft and allogenic bone. The following data were followed up in these patients: deformity angle

local recurrence

neurological function

and spinal bony fusion. Results The average operating time and blood loss was 5.6 hours and 3 400 ml respectively. No intraoperative and postoperative complications were observed in this group. Postoperatively

21 patients were Frankel grade E

2 grade D

and 1 grade C. Four patients reported significant functional restoration and twenty patients reported complete resolution of pain. At follow-up （range

6-42 months）

implant failure or recurrent neurological symptoms was not found. Conclusions The tumor resection and spinal reconstruction through single-stage posterior transpedicular approach is a safe and effective technique for the treatment of spinal tumor. It can fully decompress the neurological structures

correct the kyphosis

and achieve early weight-bearing. This technique can improve life quality for the patients with spinal tumor.
