Fig. 2. (A) Example of lordotic vertebral column (red) represented as a column with
eccentricity. (B) Column with eccentricity, e, under compression with
force, F. (C) Part of the column representing a vertebra from the
region with eccentricity, e (lordotic region), illustrating the
compressive force, F, and the induced bending moment, M. The
broken white line represents the neutral axis, and y represents the
distance from the neutral axis.
