The biomechanical effect of pedicle screw hubbing on pullout resistance in the thoracic spine

Abstract Background context The biomechanical fixation strength afforded by pedicle screws has been strongly correlated with bone mineral density. It has been postulated that “hubbing” the head of the pedicle screw against the dorsal laminar cortex provides a load-sharing effect, thereby limiting ce...
