The effect of lateral wall perforation on screw pull-out strength: a cadaveric study
BACKGROUND: Lateral pedicle wall perforations occur frequently during pedicle screw insertion. Although it is known that such an occurrence decreases the screw pull-out strength, the effect has not been quantified biomechanically. MATERIALS AND METHODS: Twenty fresh cadaveric lumbar vertebrae were h...
