Those with significant pedicle malplacement or destructive spine disorders, such as bone metabolic disease, were excluded from our study. Due to inadequate exposure of screw and malfunction of screw tail, 6 screws had no reading of extraction torque.

Normal spinal alignment preserved. Spinal hardware is used in a number of different procedures to help increase stability or facilitate healing after an injury.

Pedicle screws of non-fusion surgery placed in fractured vertebrae had significantly lower extraction torque and, therefore, could be vulnerable to loosening. As shown in Tables3 and4, the X-ray criteria of loosening had a sensitivity of 24% and a specificity of 98%, while the CT scan criterion of loosening had a sensitivity of 22% and a specificity of 96%. CT scan criterion of loosening was a no signal zone surrounding the whole body of screw on the CT image. However, in 24 patients who underwent multilevel (more than two segments) instrumentation, there was no significant difference regarding extraction torque (p=0.437) between screws placed in the end segments (n=88) and those in the mid segments (n=103), as shown in Fig. 2009;33(6):16838.
