A-C) The cancellous bone biomechanical properties of the C6 vertebra ​by micro-FEA. (A) The stress distribution image of the C6 vertebral body in the midsagittal plane. The stress distribution transfer into the ventral side of the C6 vertebra ​from the middle part at 4 weeks after CMS. (B)The stiffness and failure load of the entire C6 vertebra. CMS significantly strengthened the biomechanics in the C6 vertebra ​at 4 weeks after surgery ​and ​showed no difference between the CMS and sham groups at 8 and 12 weeks. (C) The stiffness and failure load of the C6 vertebra ​in the ventral and dorsal sides. The CMS significantly increased the ventral side of biomechanical behaviours in the C6 vertebra ​at 4 weeks, while showed no effect on the dorsal side of the C6 vertebra. * indicated P ​< ​0.05 compared with the sham group. micro-FEA = micro–finite element analysis; CMS =cervical muscle section.
