posterior decompression, posterior stabilization, spinal tuberculosis



Spinal tuberculosis can cause serious morbidity and deformity. Treatment ranging from antituberculosis drugs to surgical, and the combination thereof. In the present study, authors have shown the results of posterior decompression and posterior stabilization (PDPS) only. The purpose of this retrospective study is to evaluate the clinical and radiologic outcomes of spinal tuberculosis treated with PDPS only.


This retrospective study reviewed twenty two patients with thoracic, thoracolumbar and lumbar tuberculosis who were treated with PDPS only. There were seven males and fifteen females with a mean age of 39.3+15.4 years. The mean follow-up period was 22.6+13.4 months and the minimum duration of follow up was 12 months. Clinical outcomes (Visual Analog Scale/VAS, Short Form 36/SF-36, Os-westry Disability Index/ODI, Frankel) and radiologic results were analyzed.


The infection was resolved in all patients with no recurrence and we found no complication, intra-operative or post-operative. Mean VAS score decreased from 8.9 to 1.3 and mean ODI score also decreased from 78.9 to 10.7. The patients’s physical and mental health outcomes were improved using SF-36 survey instrument. There were significant neurologic improvement at the final follow-up based on Frankel classification. The mean kyphotic angle preoperatively was 22.6±15.7 degree which corrected to a mean of 14.9±8.0 degree with mean loss of correction of 2.8 degree at the final follow up. Fourteen (63.6%) cases achieved bony fusion.


PDPS only is a safe and effective procedure for treating spinal tuberculosis, with good improve-ment in clinical and radiologic outcomes.
