Insertion torque is not a good predictor of pedicle screw loosening after spinal instrumentation : a prospective study in 8 patients.

• In this unique human in-vivo study, the insertion torque could not be used to predict the purchase of lumbar pedicle screws one year after implantation. It could be demonstrated that in vivo insertion torque alone is of minor value to estimate pullout strength, and should be combined with or replaced by more accurate measures.
