Abstract:
[Objective]To evaluate the biomechanical efficacy of calcium phosphate cement(CPC)in augmentation and restoration of anterior cervical unicortical screw fixation.[Method]Anterior cervical unicortical screw were fixed in the cervical vertebra(C_(3~6)),pull-out test and cyclic bending test was performed and anti-shear test after cyclic bending.[Result]The pull out strength(pos)of restoration group and augmentation group were significantly higher than that in the control group,the statistic difference was also significant(P
