Abstract

The purpose of the present work was to study radio­logical changes in spinal motor segments (SMS) of white rats after degenerative spondylolisthesis had been modelled. The above modelling was carried out in 115 animals by destabilization of the anterior and posterior support complexes of their vertebral column (patent ofUkraine№ 50829). The majority of rats (79.7%) developed antelisthesis by the suggested method. Antelisthesis in young rats developed fast, increasing later gradually and on an average only by 6%. The extent of angle remodelling in young rats was significantly larger. When spondylolisthesis was modelled in rats, SMS deformities (ventrolisthesis, anteflexia, remodelling of the ventrocranial angle of the underlying vertebra) were almost the same as in people in conditions of LV spondylolisthesis (antelis­thesis, anteflexia, remodelling of the anterosuperior angle of SI body) and degenerative spondylolisthesis (remodelling of joint facets).
