In general, there are only a few mechanisms commonly used, alone or in combination, for assuring lateral stability.
一般来说，只有少数几种常用的抗力机制，单独或联合使用，确保横向稳定性。
The longitudinal, lateral and direction of this configuration can be controlled through the combination of different control devices.
通过舵面的不同组合，用于纵向、横向和航向稳定与操纵控制。
However, biomechanical studies are rare. Especially the impact of a combination of lateral mass and pedicle screws on stability in multilevel posterior stabilizations has not been evaluated until now.
然而，生物力学研究很少，尤其是在多节段后路的侧块和椎弓根螺钉组合的稳定性还没有研究。
