(Left) Measured mid-sagittal pressure profiles averaged for moderately healthy (ALDI = 0–1), degenerated (ALDI = 2), and all (ALDI = 0–2) IVDs loaded under (A) flexion and (F) compression; (Right) Color maps of the distributed load across the superior endplate for (B) Experimentally Matched, (C) Idealized, (D) IVD-Generic, and (E) IVD-Specific boundary conditions for flexion and (G) Experimentally Matched, (H) Idealized, (I) IVD-Generic, and (J) IVD-Specific boundary conditions for compression.
