The concept of chronic nonspecific back pain (CNBP) as a pathology of the spine (osteochondrosis, spondylosis, intervertebral disc herniation, facet syndrome) is extremely outdated and has not justified itself, first of all, from the therapeutic view point. Numerous studies, including meta-analyzes and systematic reviews, have convincingly shown the ineffectiveness of the methods of CNBP treatment, aimed only at solving the problems of the spine itself and / or surrounding tissues. A substantial amount of special imaging studies have proven the dissociation between morphological vertebral changes and the clinical picture of pain. CNBP is the overall result of the interaction of numerous factors in the spine tissues (changes in the discs, joints, ligaments, fascia, muscles) and factors beyond the spine. The latter include, first of all, psychological and social factors, cognitive functions, the quality of night sleep, the level of physical activity, concomitant diseases (comorbidity). In each patient, the interaction of these factors determines the development of specific pathophysiological mechanisms of pain and, as a result, an individual clinical picture of pain (phenotype). Understanding these processes will allow for the reconsideration of the approach of searching for an anatomical pain source as the main pathogenetic factor; recognizing the multifocal generation of chronic pain as the result of a complex interaction of biological, psychological and social factors; the development of new principles and therapy algorithms. The authors propose to introduce into practice a multidomain screening approach for evaluating patients with CNBP, which would take into account the phenotype of pain, factors affecting its perception, and allow personalized treatment for each patient based on the biopsychosocial approach.
