Domain of study: Pathological Anatomy.
The research purpose - evaluation of degenerative-dystrophic damage consecutiveness of the lumbar intervertebral disc with histopathological staging and assessment of biological changes (histological and immunohistochemical) produced in the compromised vertebral segments.
Objectives: Highlighting of the correspondence between histology of the degenerative changes in intervertebral discs and lumbar MRI imaging changes according thr staging of Modic. Determination of the degree and degenerative-dystrophic damage consecutiveness of lumbar intervertebral disc segments and elements. The presence of correlation between histological degenerative-dystrophic aspects of intervertebral discs and lumbar arteries stained by CD34 immunohistochemistry. Identification of the cells attend the inflammatory manifestations in the arteries, and MCT colored by CD68 immunohistochemistry and fibrillary disorganization by orcein and silver impregnation.
Scientific novelty. The correlative studies between MRI and histology of the disc in 80% of cases of herniated disc surgical histology shows changes typical advanced in the outbreak lesion and the early changes and environments, with the presence of fibroblasts reveal character regenerative kernel pulposus and annulus. Investigation of L1 lumbar arteries correlative - L5, stained with CD34, and at this level lumbar of intervertebral discs, examined histologically presents Pearson correlation index r = 0.54, average being interpreted as association, which is a clue in diagnosing degree damage to the disc.
Scientific problem solved: The degree of degeneration of the disc with stage MRI correlated at the same level, and the presence of an association between damage of the arteries wall lumbar with the intervertebral lumbar disc degeneration.
The theoretical significance. The study confirmed the usefulness and priority of the histlogical and immunohistochemical examination in assessing the degree and consistency of damage of the disc, involving of the vertebral segment structures, and stage of the vessel wall damage correlates with the degree of lumbar intervertebral disc degeneration.
The value of the work. The results obtained in the study complete the specialized medical knowledge on the diagnosis, evolution of the degenerative-dystrophic changes, perfecting tactics of treatment and prophylaxis.
