Biomechanical experiment on transoral atlantoaxial reduction plate

Objective To study biomechanical stability,including rang of motion(ROM)and pull-out strength of screws,of transoral atlantoaxial reduction plating(TARP). Methods Twelve flesh C0～C3 spine specimens were harvested.Six specimens were designed to compare ROM of TARP in 4 clinical anterior-posterior atlantoaxial arthrodeses in 7 groups:intact(control),injured,TARP,Brooks,Magerl,Magerl+Brooks,and anterior transarticular screw fixation through C2...
