The conditions for adaptation of long bones to persistent changes in the functional load have been clarified. Based on the data obtained, it was established that the influence of the mechanical factor is realized through the hydrodynamic effects of elastic deformations, which are considered as an important physiological mechanism for the regulation of intraosseous microcirculation, and, consequently, bone tissue trophism. From these positions, the significance of the functional factor in the physiological restructuring of the bone, the occurrence of certain types of orthopedic pathology, and its role in the rehabilitation of patients with diseases and injuries of the musculoskeletal system are explained.</p>structural organization of the bonetrophic influencemusculoskeletal systembone deformityструктурная организация коститрофическое влияниеопорно-двигательный аппаратдеформировании кости
