However, these surgeries pose a serious problem due to the large number of unsatisfactory results.</p> <p><bold>The aim of the study</bold> is a comparative assessment of the effectiveness between standard techniques and 3D visualization technologies in the surgical treatment of patients with elbow contractures caused by ossification.</p> <p><bold>Methods.</bold> Using random number generation, all patients (n = 71) were randomized into two groups. The first group included 34 patients with elbow contractures caused by ossification that underwent surgical intervention using 3D technologies to assess the ossification process. The second group enrolled 37 patients with a similar nosology that underwent standard examination and surgical treatment. The results were evaluated intraoperatively and 180 days after the surgery. The data were obtained from primary medical records and further survey.</p> <p><bold>Results. </bold>The application of new planning technology and tactics for onstructive plastic surgeries made it possible to reduce the surgery time by 1.2 times (p&lt;0.05), reduce blood loss by 1.3 times (p&lt;0.05) and increase the relative number of patients with sufficient movement volume by 10.6% (p&lt;0.05). The assessment of various performance parameters (range of motion, pain syndrome, quality of life etc.) showed that after 6 months in the main group, the relative number of patients with problems related to the operated joint was significantly lower than in the control group: 20.5% vs 84.7% (p&lt;0.05).</p> <p><bold>Conclusions. </bold>The data obtained indicate that the use of the new technique for planning and performing reconstructive plastic surgery in patients with elbow contractures caused by ossification contributes to a less invasive intervention and achievement of better intraoperative and medium-term treatment results.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность.</bold> Открытые реконструктивно-пластические операции являются наиболее радикальным методом лечения пациентов с контрактурами локтевого сустава, обусловленными оссификацией, однако ввиду большого количества неудовлетворительных результатов представляют собой серьезную проблему.</p> <p><bold>Цель исследования</bold> — сравнить эффективность реконструктивно-пластических операций по стандартной методике и с использованием 3D-технологий при лечении пациентов с контрактурами локтевого сустава, обусловленными оссификацией.</p> <p><bold>Материал и методы. </bold>Все пациенты (<italic>n</italic> = 71) с помощью программы генерации случайных чисел были рандомизированы в две группы. Первую группу составили 34 пациента с контрактурами локтевого сустава, обусловленными оссификацией, у которых оперативное вмешательство было выполнено с использованием нового метода визуализации на основе построения 3D-модели. Вторую группу составили 37 пациентов с аналогичной нозологией, оперированных по стандартной методике. Результаты оценивались интраоперационно и через 180 дней с момента вмешательства. Данные были получены из первичной медицинской документации и последующего анкетного опроса.</p> <p><bold>Результаты.</bold> Применение новой методики предоперационного обследования и тактики выполнения реконструктивно-пластических операций позволило сократить время вмешательства в 1,2 раза (<italic>p</italic>≤0,05), уменьшить кровопотерю в 1,3 раза (<italic>p</italic>≤0,05) и на 10,6% (<italic>p</italic>≤0,05) повысить количество пациентов с достигнутым достаточным объемом движений. Оценка различных параметров эффективности (амплитуда движений, болевой синдром, качество жизни и т.д.) показала, что через 6 мес. в первой группе количество пациентов, имеющих проблемы, связанные с оперированным суставом, было статистически значимо ниже, чем во второй группе: 20,5% против 84,7% (<italic>p</italic>≤0,05).</p> <p><bold>Заключение.</bold> Применение новой методики предоперационного обследования и выполнения реконструктивно- пластических операций у пациентов с контрактурами локтевого сустава, обусловленными оссификацией, способствуют более щадящему режиму выполнения вмешательства, достижению лучших интраоперационных и среднесрочных результатов лечения.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>elbow contracture</kwd><kwd>ossification</kwd><kwd>3D visualization technologies</kwd><kwd>reconstructive plastic surgery</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>контрактура локтевого сустава</kwd><kwd>оссификация</kwd><kwd>3D-технологии</kwd><kwd>реконструктивно-пластические операции</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Слободской А.Б., Прохоренко В.М., Бадак И.С., Воронин И.В., Дунаев А.Г.
