Displacement data with time obtained for the full mechanical testing protocol for a typical (A) explant and (B) motion segment. Displacement point’s d1, d2, d3, d4, and d5 refer to the displacement after 4 h at 0.04 MPa, after 4 h at 0.2 MPa, after 6 h of recovery following the 0.2MPa load, after 4 h at 1.0MPa and after 6 h of recovery following the 1.0MPa load, respectively. These markers are slightly offset from data for increased visibility.
