Результаты работы показали, что изменение плотности различных отделов бедренной и большеберцовой костей до и после удлинения имело нозологические особенности, органотипическая перестройка удлиненной кости завершалась через 1-3 года с колебаниями в зависимости от этиологии заболевания, степени патоморфологических и биомеханических изменений, функции конечности. Плотность кортикальной пластинки во время удлинения и в периоде фиксации снижалась на 200-300  HU, а после снятия аппарата увеличивалась на 300-400  HU, что свидетельствует о нормальном течении процессов ремоделирования костной ткани после удлинения.</p></abstract><trans-abstract xml:lang="en"><p>116 patients with limb shortenings and deformities of different etiology have been examined to study the condition of maternal bone before and after lengthening using the techniques of computer tomography (CT) and those of magnetic-resonance one (MRT). The results obtained demonstrated that the change in the density of different femoral and tibial parts before and after treatment was characterized by nosological features, the organotypical reorganization of the bone lengthened was completed within 1-3-year period with variations depending on disease etiology, the degree of pathomorphological and biomechanical changes, limb function. The density of cortical plate during lengthening and in the period of fixation 200-300 HU decreased, and after fixator removal it 300-400 HU increased, thereby demonstrating the normal processes of bone tissue remodeling after lengthening.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title></ref-list><fn-group><fn fn-type="conflict"><p>The authors declare that there are no conflicts of interest present.</p></fn></fn-group></back></article>
