Methods Six cadaveric lumbar vertebrae were harvested and evaluated with dual-energy x-ray absorptiometry and quantitative computed tomography to assess bone mineral density. Matched, polyaxial pedicle screws were then randomly assigned by side and placed using the Magerl, Krag or caudad trajectory technique assisted by Iso-C 3D scan and 3D navigation system. Cyclic loading tests were performed with a maximum 250 N load at 3 Hz up to 30000 cycles while recording load and displacement. Stiffness quotients were calculated it comparison.
