Abstract
Objective To compare the cervical biomechanical stability of lateral fixation piece and pedicle screws of screw fixation.Methods The 12 cervical vertebras as experimental sample,and from C4 to C5 were cut off and caused cervical instability model.Three ways of non fixation,lateral mass screw fixation and pedicle screw fixation were implemented.Then flexibility and rotation torque and stiffness were tested.Stability of two kinds of internal fixation was evaluated.Results In the 3-D range of movement,lateral mass screw fixation was notably smaller than that of pedicle screws fixation (P ＜ 0.05).The lateral mass screw fixation had more strength than pedicle screws fixation (P ＜ 0.05).Conclusion The instability of lower cervical spine patients may use lateral mass screw fixation,and its biomechanical stability is better.关键词
