Implementation of new spine stabilisation systems should be preceded by the analysis of the behaviour of healthy and damaged spine under laboratory conditions. Research was performed on two-part and three-part segments without damage and with disc damage in the two-part segment, and with a wedge cut in the vertebra in the three-part segment. In the two-part segment, a relative power necessary for inducing extension-compression in the damaged segment is twice as high as in the damaged three-part segment. In the damaged two-part segment, the motion in the sagittal plane needs a relative power being more than twice as high as in the damaged three-part segment. Yet absolute average values of powers examined in the two-part and three-part segment systems in the undamaged spine for all types of motion were similar, with slight advantage of the two-part segment system. Basic two-part segment of the spine motion system is its most stable functional part.
