Surgeons use their subjective assessment to determine how much screws should be tightened. However, it is unknown what stopping torque generates the optimum fixation as determined by screw compression and pullout strength. Further to this, screws are frequently over-tightened leading to bone stripping and fixation failures; these are associated with increased morbidity and mortality. As screw fixation failure is commoni, and predicting stripping torque can be difficult, identifying the limits and optimum zone for screw tightness should reduce failures thus generating significant health and economic benefits.
