What happens to atoms during chemical reaction? In our study, we also found a significant linear correlation between BMD and extraction torque, indicating pedicle screws in aged patients or patients with lower BMD might be less stable due to lower extraction torque. Therefore, we intended to investigate the pedicle screw loosening rate using extraction torques during instrumentation removal surgery, and compare it with X-ray and CT image findings. Nevertheless, the specific details regarding X-ray criteria of loosening were not described in most papers, suggesting that the subjective viewpoints of surgeon and radiologist played an important role.

Linear regression analysis was used to estimate the relevance between the extraction torque of pedicle screw and other clinical findings. Other factors that could cause bone loss or destruction, such as infection surrounding the implant, bone tumor, metabolic diseases, and microfracture due to excessive loading, are risk factors of pedicle screw loosening.
