It does not store any personal data. One of the typical complications widely reported in literatures is screw loosening, which may lead to fixation failure and require revision surgery [3]. Sanden [20] reported a 64% sensitivity of X-ray in 79 screws and a 35% rate of screw loosening, but their definition of a loosed screw was an extraction torque of 0.4Nm or less as there were no screws with and extraction torque between 0.4Nm and 0.75Nm. The goal of a spinal fusion is to stabilize the spinal column and provide support to any degenerative vertebra. a No significant difference was found between polyaxial and monoaxial screws. As expected, extraction torques of pedicle screw after fusion surgery (n=142) were significantly higher than those in non-fusion surgery (n=84) (p=0.001), as shown in Fig. Breakage of hardware can also be the result of a particularly unstable spine.
