Objective To determine if calcium phosphate cement can enhance vertebralpedicle screw fixation in the osteoporotic spine through periodical anti-bending test.
目的本实验旨在从周期抗屈试验方面证实磷酸钙骨水泥对椎弓根螺钉固定的强化作用。

There were three significant independent predictors of increased total cost: the surgical approach used, the number of pedicle screws placed, and the number of vertebral levels fused.
有三个显着的显著因素能增加总成本:采用手术的方法,椎弓根螺钉的放置数量,以及脊椎融合数。
