Extraction torque of pedicle screws inserted in fractured vertebrae was significantly lower than those in non-fractured vertebrae (p=0.009); meanwhile, screws of non-fusion surgery had lower extraction torque when compared to those in fusion surgery (p=0.001). As expected, linear regression analysis showed that the stability of pedicle screw correlated positively with BMD and negatively with patients age. Using X-ray radiographs taken the day before removal operations, radiolucent area (wider than 1mm) around the screw and/or the double halo were detected in 20 screws.

Influence of bone mineral density on pedicle screw fixation: a study of pedicle screw fixation augmenting posterior lumbar interbody fusion in elderly patients. This result indicated that both radiological examinations were effective to confirm loosening screws; however, the low sensitivity implied a considerable number of loosening screws could be neglected by imaging study. A comparative study on screw loosening in osteoporotic lumbar spine fusion between expandable and conventional pedicle screws. In my practice, I often order a CT scan around 3 months to verify the instrumentation is not loose and there are early signs of bone growth (fusion).
