Imaging of bones dysbarogenic changes in navy divers

The number of diving descents in the world is steadily growing, as is the complexity of the work performed under conditions of increased environmental pressure. Also, in order to increase efficiency and expand the range of tasks performed, the intensity, depth of dives and the time divers spend in hyperbaric conditions are increasing. These factors contribute to an increase in the number of diving pathologies, including damage to the skeletal bones of dysbarogenic genesis. X-ray diagnostic methods used during annual medical examinations of divers do not always allow the detection of dysbarogenic changes in the bones; in addition, the clinical manifestations of this pathology do not have obvious specificity. In this regard, it can be assumed that the occurrence of this pathology among divers has not been reliably established to date. This article is devoted to a review of the literature on the possibilities of radiodiagnosis of dysbarogenic changes in skeletal bones in specialists whose work involves being in conditions of high environmental pressure. The article highlights the results of a literature review of English-language and Russian-language publications presented in the databases of PubMed and scientific electronic libraries of Russia (eLIBRARY.RU and CYBERLENINKA.RU). In order to determine the optimal methods of radiation diagnostics, the etiological and pathogenetic aspects of the development of dysbarogenic degenerative and necrotic changes in the bones of the skeleton, as well as the experience of scientists in determining the corresponding radiation semiotics, were analyzed. Considering that the worst manifestation of bone pathology of dysbarogenic origin is dysbaric (aseptic) osteonecrosis, we studied the literature on the issues of its clinical and instrumental diagnosis. One of the directions in scientific research was the work of authors exploring the possibilities of early instrumental diagnosis of changes in bone tissue, in particular the possibilities of magnetic resonance imaging in the diagnosis of dysbaric osteonecrosis. In addition, data on modern x-ray methods were analyzed, which may be promising as a screening diagnosis of dysbarogenic degenerative and necrotic changes in the bones of the skeleton.
