Fig. 7.

Fibre strain (a) Anterior fibre strains are overall compressive (shortening from reference state) with some local variation of higher compression and tension toward the superior vertebral body. (bi) Posterior-lateral fibre strain magnitudes are generally higher when compared to anterior measurements. (bii) Inner posterior-lateral fibres show a general trend toward compressive strain with tensile strain observed near the endplate junction (box) (c) Comparison of fibre strain between regions. Overall, there is a balance between tensile and compressive strain (lengthening and shortening) with anterior fibre strains collectively lower in magnitude than in the posterior-lateral region.
