The mechanical properties of the human lumbar annulus fibrosus is investigated both
theoretically and experimentally. The theory presented is based on the assumption of …

We investigated the tensile properties of samples of human lumbar annulus fibrosus. Here
we consider the effect of sample size, and hence collagen disruption, on the results …

An analysis of the bulging of the annulus fibrosus as a function of the height of the
intervertebral disc during compression is presented. The theory was compared with the …

A simple model is presented that explains the observed function and failure of the
intervertebral disc in compression, torsion, and bending; this model is based upon the …

Function, failure, and remodeling of the intervertebral disc are all related to the stress and
strain fields in the tissue and may be calculatd by finite element models with accurate …

Part I of this study showed that collagen fibres do need not need to be continuous to
reinforce the annulus fibrosus, and that 15-mm-wide samples of annulus retain about 44% of …

The mechanical behavior of the entire anulus fibrosus is determined essentially by the
tensile properties of its lamellae, their fiber orientations, and the regional variation of these …

Years ago this laboratory started to construct devices in which parts of the spine were
subjected to forces and the relations between vertebrae recorded (1). The deformations of …

We conducted an in vitro study of the radial tensile properties of the annulus fibrosus. The
stress‐strain response was nonlinear, with a mean tangent modulus of 0.19 MPa at zero …
