Abstract :
We thank Dr. Meena and colleagues for their interest in our study. We note that there were statistically significant differences in the preoperative kyphosis angle in the anterior and posterior groups because there were more patients with thoracic spinal tuberculosis (TB) in the anterior group than in the posterior group, who had physiological kyphosis. It is a fact that the spinal TB rarely affects the pedicle part of the vertebra, so the pedicle screw is stronger than the vertebral screw when the vertebra is infected by TB. The 28 patients with a kyphosis angle between 61 and 70° were managed by posterior instrumentation with posterior column shortening along with simultaneous or staged anterior radical debridement plus bone grafting.
