Can Prevention of a Reherniation Be Investigated? Establishment of a Herniation Model and Experiments With an Anular Closure Device

Abstract

We established a human herniation model that reliably produced nucleus extrusion during cyclic loading by selecting specimens with low disc degeneration. The Barricaid seems to prevent nucleus from reherniating. The reliability of this method suggests the opportunity to investigate other anulus closure devices and nucleus replacement techniques critically.
