title: [The structure of the cartilage of the zygapophyseal articulations of the human spine in the stages of postnatal ontogeny].
abstract: The structure of articulationes zygapophysiales joints cartilage of vertebral column lumbar region was studied in three age groups of 20-29, 30-39 and 40-49 years. The articular cartilage studied was similar in its structural organization and the character of age changes with those in large synovial joints, however it was distinctly peculiar in the development of involutive changes. Both cells and matrix components of articulationes zygapophysiales joints cartilage display changes already in 20-29 years group. There are significant differences in the degree of destructive and dystrophic changes manifestations in articular facets within one joint. These changes were found to prevail in articular cartilage of superior articular process of the vertebral body inferior to the joint.
