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.

从尸体中获取6节腰椎椎体经DEXA和QCT检测骨密度值，证实为骨质疏松后在计算机导航下按随机分组的方法向12个椎弓根中置人不同方向的椎弓根螺钉，使用MTS-858生物力学仪脊柱力学测试平台进行±250N的循环负荷疲劳测试，记录负荷循环中的螺钉位移，计算系统的刚度系数并进行对比分析。

The incidence of junctional kyphosis and its association to the above parameters and to fusion levels were assessed.
