The transverse process C2 plays an important role in the stabilization of the vertebral unit C2/C3 and the protection of the vertebral artery and the cervical spinal cord. The anatomical disposition of the transverse processes C2 and especially the lateral processes may be different from one subject to another. Certain anatomical variants of the transverse(More)
Investigations were conducted with macerated cervical vertebrae and human cadavers. During extension, lateral flexion, and rotation of the neck, the cervical transverse process engages to the top of the upper articular process of the subjacent vertebra, thus embodying the locking mechanism which plays an important role in the stabilization of the cervical(More)
In the paper it is endeavoured to set up objective criteria for the detection of a qualitatively abnormal mobility of the cervical vertebral units. Three scalar parameters were chosed to characterize the position of a cervical vertebra in the sagittal plane. By the aid of the parameters, graphs were drawn illustrating the reciprocal functional dependence of(More)
