The difference of curvature and elasticity modulus between different Pfirrmann grade groups. A, D The involved disc shows focal lordosis in the low Pfirrmann grade group. B, E The involved disc shows focal lordosis in the high Pfirrmann grade group. C The comparison of cervical curvature between the two groups. F The comparison of elasticity modulus between the two groups. *p < 0.05
