STUDY DESIGN A biomechanical study comparing the fatigue strength of different types of C2 fixation in a C1-C2 construct. OBJECTIVE To determine the pullout strength of a C2 pedicle screw and C2 pars screw after cyclical testing and differentiate differences in stiffness pre- and post-cyclical loading of 3 different C1-C2 fixations. SUMMARY OF BACKGROUND DATA Some surgeons use a short C2 pars screw in a C1-C2 construct, because it is less technically demanding and/or when the vertebral… CONTINUE READING
