Possibilities of systemic analysis of radiographs of patients with degenerative diseases of the spine

The criteria for the evaluation of a separate vertebra statics were distinguished. Those criteria were taken as a principle for systemic analysis of spine radiograms. Structural shape and spatial position disturbances of the separate vertebrae, mobile motor spinal segments as well as the whole spine were reflected in algorythmic description and diagrams. 452 patients, aged 6- 76 years, were examined using that method. Degenerative dystrophic diseases were detected in 79% of patients, statics disturbances in 17-21.9%), different malformations in 0.9-20.4% of cases. On the base of examination data a computer model of normal spine was created and the influence of sacrum position and thoracic kyphosis peculiarities on the level, rate and direction of cervical and lumbar spondylolisthesis was studied.
