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.

In the experiment with 22 dogs the authors have studied the effect of the spine shortening on the undamaged and damaged spinal cord. Observation period ranged from 1 week to 6 months. Partial resection of the vertebral body without spine shortening, practically, have not affected the spinal cord of an animal. Spine shortening without the spine cord transection is accompanied by the spinal cord crumpling and partial damaging. Combination of this operation with submembrane transection of the spinal cord permits to avoid an obvious scar formation but results in considerable cyst-formation that prevents regenerative process in the spinal cord. Further studies should be conducted in terms of the cyst-formation process prevention.

On the basis of experimental and clinical investigations the authors consider the removal of the vertebra body as the whole block to be the optimal variant. Shortening of the vertebral column is permissible for the approximation of ends of the spinal cord or its roots for suturing without intention. The use of vertebrectomy in 9 patients with long-standing dislocation fractures and defects of the spinal cord tissues from 1 to 12 cm and in 4 patient without tumors of the vertebrae has shown that the operation with removal of as many as 3 vertebrae is quite realizable technically. However, positive clinical results are minimal for the present which requires further researches by stimulation of regenerative processes.
The use of vertebrectomy in 9 patients with long-standing complicated dislocation fractures of vertebrae and defects of tissues of the spinal cord from 1 up to 12 cm has shown that the operation of removal of up to 3 vertebrae is technically quite realizable. Clinical results however are yet minimum, which requires further search for methods of stimulation of regenerative processes in the zone of connection of the spinal cord stumps. The use of the method for treatment of 4 patients with tumors of the vertebrae has revealed a number of problems requiring a somewhat different approach both to the performance of the operation and to the following fixation of the backbone. Possible variants to settle the problems are proposed. Good prospects of this trend are noted.
