Abstract:
Objective: To compare the fixation strength of locking and non-locking anterior cervical plating initially and after fatigue.Methods:AO Cervical Spine Locking Plate(CSLP),Danek Orion plate and AcroMed Acroplate were fixed on lamb cervical spine.The fixation strength and pull-off strength of the screw-plate constructions was performed initially and after fatigue.Results:Locked CSLP and Orion constructions were more rigid than all unlocked unicortical systems initially and after cyclic loading.There was no significant difference in pull-off strength between the CSLP,the Orion,and the unicortical Acroplate.Conclusions:Locking mechanism significantly increased the strength of the tested screw-plate systems initially and after fatigue.
