“…However, by necessity, the in vivo studies apply impacts below the injury threshold. Mathematical models for whiplash simulation of the cervical spine include multibody lumped-parameter [19,20,29, 39] and finite-element method models [12,15,52,87]. While mathematical models can incorporate detailed spinal anatomy, including muscles, the output data are highly dependent upon the accuracy of the input data, such as the dynamic mechanical properties of the soft tissues (ligaments and discs) and the muscle activation patterns.…”

“…Some authors proposed nonlinear models [39][40][41]. Due to common use of the finite element method in numerical simulations, shell and beam models [33] as well as the spring and axial (link) ones [42] have become popular.…”

“…In order to take into account the acting loads, the discs were divided into three parts: annulus, annulus fibrosus and nucleus pulposus. In [33,37] authors proposed discs comprised of two bodies representing the annulus and nucleus. Goel et al [44] additionally applied a beam model for the annulus fibrosus.…”

“…De Jager et al [31,32] developed the model of Deng and Goldsmith by assumption that the head and vertebrae are rigid members but discs are represented through viscoelastic joints with nonlinear characteristics determined experimentally. Yang et al [33] analyzed motion of the cervical spine in sagittal plane leading to spinal injuries. In this model both elastic and viscoelastic nature of the ligaments was considered.…”

Application of the MEBDFV code in multibody dynamics is discussed. The solver is based on the modified extended backward differentiation formulae of Cash. It is especially suited for the solution of differential-algebraic equations with time-and state-dependent mass matrix. Such a case can occur when motion of a multibody open-chain system is described within the classical Lagrangian formalism, which still has some advantages. An outline of the numerical algorithm is given. As an example, a simplified mathematical model of the human head-cervical spine system is presented. In a numerical experiment the model is used to analyze motion of the head-neck during rear-end impact which may lead to whiplash injury. The obtained results are compared to literature data. Performance of the MEBDFV solver is examined in terms of algorithmic energy conservation. The test is based on an appropriately formulated 'kinetic energy-work' relation.

“…The model reported by Yang et al [13] included linear viscoelastic discs, with ligaments and muscles possessing only passive behaviour. They claimed that the model was validated with reasonable success against the head and neck drop tests as well as cadaveric sled tests.…”

This article presents the effects of the frontal and rear-end impact loadings on the cervical spine components by using a multibody dynamic model of the head and neck, and a viscoelastic finite element (FE) model of the six cervical intervertebral discs. A threedimensional multi-body model of the human head and neck is used to simulate 15 g frontal and 8.5 g rear-end impacts. The load history at each intervertebral joint from the predictions of the multi-body model is used as dynamic loading boundary conditions for the FE model of the intervertebral discs. The results from the multi-body model simulations, such as the intervertebral disc loadings in the form of compressive, tensile, and shear forces and moments, and from the FE analysis such as the von Mises stresses in the intervertebral discs are analysed. This study shows that the proposed approach that uses dynamic loading conditions from the multi-body model as input to the FE model has the potential to investigate the kinetics and the kinematics of the cervical spine and its components together with the biomechanical response of the intervertebral discs under the complex dynamic loading history.
