We constructed a linear regression model with Pearson correlations analysis to assess whether clinical data, such as age and BMD, were correlated with the extraction torque of screw. Pedicle screws of non-fusion surgery placed in fractured vertebrae had significantly lower extraction torque and, therefore, could be vulnerable to loosening. Since 1.02Nm was significantly less than the 95% confidence interval of newly implanted screws, the pedicle screw loosening based on torque was defined as screws with an extraction torque less than or equal to 1.02Nm. How to tell if a screw is coming loose? This consequence is extremely uncommon. p=0.01, R2=0.267, F=8.296, Linear regression analysis, Scatter diagram of patients average torques and ages.

Despite tremendous technical advances in spine surgery in recent decades, patients may experience residual or recurrent pain and other symptoms after such surgery. Christensen FB, Dalstra M, Sejling F, Overgaard S, Bunger C. Titanium-alloy enhances bone-pedicle screw fixation: mechanical and histomorphometrical results of titanium-alloy versus stainless steel. Don't want surgery but if I can get rid of this pain, I have to go for it. 6). The relatively low related coefficients might be due to the existence of numerous confounding factors, and these results indicated that the failure risk of instrumentation increased with age and osteopenia/osteoporosis, which was widely credited but rarely proven in vivo with mechanical measurement. Manage cookies/Do not sell my data we use in the preference centre. Pedicle screw fixation is widely used in spine surgery for numbers of indications, such as degenerative disease, trauma, tumor, infection, and deformity.
