A new non-laminectomy model of the spinal cord injury: pressure impactor

Gzik M., Tejszerewska D., Bobrowski M.

Acta of Bioengineering and Biomechanics

2006

Vol. 8, nr 2

89-95

The influence of air pressure impact on rat spinal cord injuries is presented. In order to verify the non-laminectomy model of spinal cord injury, a professional device was designed. The device is based on pneumatic solution and gives the opportunity to carry out repeatable, unlimited, controlled experiments without the necessity of an extensive opening of the vertebral canal.

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.
