TomoSAXS in intact intervertebral discs shows intrafibrillar molecular pre-strain (D-period stagger) is lamellar textured and tightly correlated with microscale fibre strain.
- Why it matters: It addresses how fibril-scale mechanics couple to fibre-scale organization in load-bearing spinal tissue, which has remained unresolved.
- What they did: The study uses full-field 3D small-angle X-ray scattering tomography to map fibril-to-fibre mechanics in intact IVDs and relate pre-strain to local fibre strain.
- The result: Pre-strain is inversely related to fibril strain and its variability, and radial strain bridges plus high-curvature zones at the annulus fibrosus–nucleus pulposus interface emerge as key local regulators.
