Quantitative comparison of a laterally misplaced pedicle screw with a re-directed screw. How much pull-out strength is lost?
Objective: Redirecting of a laterally misplaced pedicle screw into the accurate position decreases the pull-out strength due to the reinsertion, lateral wall cortical perforation and widening of the pedicle hole. Thus, this biomechanical study was performed to quantitatively analyze the pullout stre...
