Internal forces in the spine modelled as an arch
journal contribution
posted on 2013-12-18, 09:13 authored by Di-Chen Xiao, Keith CaseKeith Case, Serpil Acar, J. Mark PorterThe work reported here presents a parametric solid model of the spine, loading systems
of the spine and a extracted arch spine model in which the body weight and external
loads are treated as forces applied at appropriate points on the spine and muscle and
ligament forces are treated as reaction forces applied to both ends of the spine. The
model extends the arch spine approach by using optimisation techniques to find a better
fitting thrust line compared with the previous arch model in the literature, and calculates
the internal forces between the vertebrae in the spine. Case studies show the reasonable
values of the internal forces (1.1-1.5 kN) in the arch spine. The values are much less than
that of lever models (up to 6.6 kN).
