| Summary: | Objective To study morphological and radiological parameters of facet joints depending on the grade of the intervertebral disk degeneration. Materials
and methods To study the facet joints of the lumbar spine in 145 patients with various grades of degeneration according to Pfirrmann and treated using
rigid fixation and TLIF technology, MSCT in 2-energy mode and morphological investigation of the intraoperative material were performed. Results In
Pfirrmann grade 2, an increase in the volumetric content of chondrocytes, Hounsfield density of the cartilage plate, and the level of Ca in the facet joints was
visualized. They indicate that the joint remains functional. In Pfirrmann grade 5, deep pathological changes occurred with violation of the architectonics of
the cartilage formations of the facet joints, formation of bone elements and connective tissue growth into the cartilage and bone structures of the joint, which
correlated with the results of MSCT. Conclusion The data obtained show that there is a close relationship between morphological and radiological changes
in the facet joints. Modulating the data obtained allows us to obtain objective criteria for evaluating the grade of pathological processes in facet joints and
use them as a diagnostic component when planning decompression and stabilizing operations in patients with degenerative diseases of the lumbar spine. |
