Abstract
Long Construct Pedicle Screw Reduction and Residual Forces are Decreased Using a Computer-assisted Rod Bending System
Previous biomechanical studies have shown that reduction loads placed on pedicle screws during assembly of the construct, with a rod that does not adequately fit the screw locations, can reduce the strength of the screw-bone interfaces. In this bench top study, axial pedicle screw forces on a unilateral 7-level construct were evaluated for 2 rod bending techniques: manual and computerassisted.
