Modelling of dynamic interactions in cervical spine during car collision

Gzik M., Tejszerewska D.

Acta of Bioengineering and Biomechanics

2000

Vol. 2, nr 2

33-40

The paper presents a dynamic spatial mathematical model in which a head, two cervical vertebrae, a group of neck muscles, an intervertebral disc, ligaments and intervertebral joints are taken into consideration. The behaviour of modelled body exposed to action of a force corresponding to the real enforcement, which occurred at a head-on collision during the road accident, was simulated, and the model was verified on the basis of data obtained from published experiments.

Biomechanical model of the human cervical spine

Tejszerska D., Gzik M.

Acta of Bioengineering and Biomechanics

1999

Vol. 1, nr 2

39-48

The paper describes the biomechanical model simulating dynamic phenomena in the human cervical spine caused by assumed acceleration and external impact on head and trunk, especially in car accident. The model assumption, generals equations describing dynamic equilibrium of spine members and detailed analysis of important elements are presented. The method of solving obtained set of equations is described.
