The degenerative state of the intervertebral disk independently predicts the failure of human lumbar spine to high rate loading: An experimental study
2015, Clinical BiomechanicsCitation Excerpt :T2 weighted magnetic resonance (MR) images provide assessments of anatomical features and an inferred hydration state of the disk (Boos et al., 1993; Boss et al., 1993; Tertti et al., 1991) while T1 and T2 relaxation rates demonstrate inverse relationships with disk water (Crooks et al., 1987; Fullerton and Camron, 1988) and glycosaminoglycan content (Boos and Boesch, 1995). Degenerative changes in the annulus and nucleus, which strongly affect their static and viscoelastic material properties (Acaroglu et al., 1995; Ebara et al., 1996; Iatridis et al., 1998) and the associated loss of hydration (Best et al., 1994; Galante, 1967; Panagiotacopulos et al., 1987), result in the degradation of the FSU's long-term creep behavior and energy dissipation (Best et al., 1994; Lai et al., 1991; Laible et al., 1993). Although hydration and the degenerative state of the disk are important determinants of the spine's stiffness and damping characteristics, little is known about their effect on the failure load of elderly spines under high rate loading (Sran and Robinovitch, 2008; Toen et al., 2012).
