Also, there are no accurate age indications for surgery. The conducted research has shown that the course of CPC is accompanied by clavicle shortening as well as by bone fragments deformation in 60% of the cases, which has a significant effect on the planning of surgery.</italic></p> <p><bold><italic>Purpose</italic></bold><bold><italic> of study: </italic></bold><italic>to</italic><italic> develop a differentiated approach to the treatment of congenital pseudoarthrosis of the clavicle in children, taking into account the clinical and radiological picture.</italic></p> <p><bold><italic>Patients</italic></bold><bold><italic> and methods. </italic></bold><italic>27 patients with the congenital pseudoarthrosis of the clavicle (CPC) aged from 4 up to 16 years old were operated. In 6 observations bone fragments deformation of the clavicle was absent, and in 21 observations various deformations occurred. The surgery included restoration of clavicle axis, replacement of bone tissue defect with bone autograft, fixation of bone fragments with a needle.</italic></p> <p><bold><italic>Results</italic></bold><bold><italic>. </italic></bold><italic>After</italic><italic> the first surgery, bone fragments consolidation of the false joint was reached in 82% of the cases </italic><italic>(22 patients); the recurrence of the false joint was observed in 18% (5 patients). Repeated surgeries were successfully performed on four of them; one patient is being observed on an outpatient basis.</italic></p> <p><bold><italic>Conclusion</italic></bold><bold><italic>. </italic></bold><italic>The</italic><italic> results of the surgical treatment have shown that for the union of a false joint it is necessary to use differentiated approach to the adoption of surgical technique with regard to bone fragments deformation. Partially eliminated deformation and clavicle sternal bone fragment high standing served as the main reason for the recurrence of pseudoarthrosis.</italic></p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Введение. </italic></bold><italic>Вопрос о показаниях к хирургическому лечению врожденных ложных суставов ключицы (ВЛСК) вызывает дискуссии среди врачей-ортопедов. Отсутствуют четкие возрастные показания для хирургического вмешательства. Проведенные исследования подтвердили, что течение ВЛСК сопровождается укорочением ключицы, а также в 67% случаев — деформацией костных фрагментов, что весьма существенно при планировании оперативного вмешательства.</italic></p> <p><bold><italic>Цель исследования: </italic></bold><italic>разработать дифференцированный подход к лечению врожденных ложных суставов ключицы у детей с учетом клинико-рентгенологической картины.</italic></p> <p><bold><italic>Пациенты и методы. </italic></bold><italic>Прооперированы 27 пациентов с ВЛСК в возрасте от 4 до 16 лет. У 21 пациента имели место разные варианты деформации фрагментов ключицы. Хирургическое вмешательство включало восстановление оси ключицы, замещение дефекта костной ткани костным аутотрансплантатом, фиксацию костных фрагментов.</italic></p> <p><bold><italic>Результаты. </italic></bold><italic>Консолидация костных фрагментов ложного сустава после первого вмешательства была достигнута у 22(81,5%) пациентов. У 5(18,5%) больных констатировали рецидив ложного сустава, из них 4 были успешно выполнены повторные оперативные вмешательства,1 пациент наблюдается амбулаторно.</italic></p> <p><italic><bold>Заключение. </bold>Для сращения ложного сустава необходим дифференцированный подход к выбору методики хирургического вмешательства, учитывающий вариант деформации костных фрагментов. Основными причинами рецидива ложного сустава являлись неустраненная деформация и высокое стояние стернального костного фрагмента ключицы.</italic></p></trans-abstract><kwd-group xml:lang="en"><kwd>congenital false joint of a clavicle</kwd><kwd>congenital pseudoarthrosis of the clavicle</kwd><kwd>bone fragments deformation</kwd><kwd>bone plasticity</kwd><kwd>differentiated approach</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>врожденный ложный сустав ключицы</kwd><kwd>деформации фрагментов ключицы</kwd><kwd>костная пластика</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Fitzwilliams D.
