Vertebra C2 causes numerous difficulties in post-traumatic stabilization because of a special character of injury resulting from its untypical structure due to its function. Understanding of the mechanism of C2 vertebra injury has a crucial importance for the treatment process and also for the development of new stabilization techniques in C2 vertebra dens (odontoid process) breakage. A series of endurance tests has been carried out to determine the value of force which breaks a vertebra dens and the character of a resulting breakage. The tests were carried out with the use of a material testing machinę for nine section preparations. Cause and effect-type conncctions have been established between the results obtained and individual features of the vertebrae tested. The recognition of the value of injuring force makes predicting the occurrence of C2 vertebra injury resulting from a simulated bending mechanism possible.
