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.

The results are presented of pathomorphological studies and clinical examinations of 572 patients with lumbar zygo-apophyseal joint arthrosis using arthrography, intraarticular treatment- and- diagnostic blockades, intracutaneous joint denervation and surgical treatment of arthrogenous lumbar canal stenosis. Based on the data obtained, the pathogenetic classification of lumbar spondyloarthrosis has been elaborated and presented in the given paper.

The data of pathomorphologic investigations of intervertebral ++ joints of the lumbar++ part of spine in case of osteochondrosis and in connection with age are presented in the article. 32 arthrograms of ++ intervertebral++ joint, taken in the patients' lifetime, have been analyzed. The special features of morphologic changes have been revealed and their connection with the clinical signs of osteochondrosis has been determined.
