The IDP measurements during the flexibility tests showed a similar tendency (Fig. 7). The box-cut defect led to a decrease in the IDP, except for extension and left AR (Fig. 7). Accordingly to the findings in ROM and DH, after the prolapse and removal of the nucleus material, IDP decreased in all motion directions (Fig. 7). Only in flexion, a slight increase was measured. The implantation of the native collagen-type-I nucleus implant and annulus closure device increased IDP again, so that the initial values of the intact specimens have been reached in all motion directions. After the long-term cyclic loading with 100,000 load cycles, IDP did change, but not following the same pattern for different loading planes as it could be observed for the ROM (Figs. 6, 7).
