A: Comparison of the results from the finite element study to the cadaver study PROM results in flexion/extension, axial rotation and lateral bending for lateral mass screw construct. The finite element ROM results corresponded well with the cadaver study results in all loading modes. B: Comparison of the results from the finite element study to the cadaver study PROM results in flexion/extension, axial rotation, and lateral bending for pedicle screw construct. The finite element ROM results corresponded well with the cadaver study results in all loading modes. C: Comparison of the results from the finite element study to the cadaver study PROM results in flexion/extension, axial rotation, and lateral bending for lamina screw construct. The finite element ROM results corresponded well with the cadaver study results in all loading modes. FEA: finite element analysis, PROM: percentage range of motion, ROM: range of motion.
