The hierarchical organization of collagen fibrils in the intervertebral disc is characterized by structural gradients. In the annulus fibrosus, the thickness of lamellae increases abruptly 2 mm inward from the edge of the disc, dividing the annulus into peripheral and transitional regions. Lamellae in the lateral and posterior annulus have a broad distribution of lamellar thicknesses. In alternate lamellae, fibrils are inclined with respect to the vertical axis of the spine in a lay-up… Expand
