They share their experience in using loop threads for tendon suturing in zones II, III, IV, V including tendon end reinsertion in zone I again with a loop thread. The primary task of surgical treatment of children with injured tendons of finger flexors is their restoration. In order to prevent secondary tendon ruptures, finger contractures, infectious complications and scarring of the tendon with surrounding tissues, it is recommended to use optimal suture material and surgical sutures that meets the basic requirements for tendon suturing . Specific pediatric anatomy must be taken into consideration as well. As the authors' clinical experience shows, a new approach to the restoration of injured finger flexor tendons with loop threads allows to avoid complications in 98% of cases.</p> <p><bold><italic>CONCLUSION: </italic></bold>The implementation of loop tendon suturing into pediatric practice in combination with appropriate rehabilitation and motivation for the rehabilitation of a child and his/her parents opens up new prospects for the successful treatment of children with injured tendons of deep flexors of hand fingers.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Несмотря на существенный прогресс в развитии хирургии кисти, на сегодняшний день число неудовлетворительных функциональных результатов лечения повреждений сухожилий сгибателей пальцев кисти остаётся высоким, что подчёркивает важность и значимость проблемы восстановления сухожилий сгибателей у детей.</p> <p><bold>Описание клинического случая. </bold>В этой публикации мы представляем серию клинических случаев применения петлевой нити при выполнении сухожильного шва у детей с травмами сухожилий глубоких сгибателей пальцев кисти во 2–5 анатомических зонах и случай реинсерции конца сухожилия в зоне 1 с помощью петлевой нити.</p> <p>Восстановление сухожилий — первостепенная задача при хирургическом лечении детей с повреждениями сгибателей пальцев кисти. Для профилактики вторичных разрывов сухожилий, контрактур пальцев, инфекционных осложнений и рубцовых сращений сухожилий с окружающими тканями рекомендовано использовать оптимальный шовный материал и хирургический шов, соответствующий основным требованиям и учитывающий детскую анатомию. Новый подход к восстановлению сухожилий сгибателей пальцев кисти с помощью петлевой нити, согласно данным нашего клинического опыта, позволяет избежать осложнений в 98% случаев.</p> <p><bold>Заключение.</bold> Внедрение в практику петлевого сухожильного шва в комбинации с реабилитацией, мотивированностью ребёнка и его родителей открывает новые перспективы для успешного лечения детей с повреждениями сухожилий глубоких сгибателей пальцев кисти.</p></trans-abstract><kwd-group xml:lang="en"><kwd>clinical case</kwd><kwd>deep finger flexor tendon</kwd><kwd>children</kwd><kwd>loop sutures</kwd><kwd>loop tendon suture</kwd><kwd>critical zone</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>клинический случай</kwd><kwd>сухожилие глубокого сгибателя пальца кисти</kwd><kwd>дети</kwd><kwd>петлевая нить</kwd><kwd>петлевой сухожильный шов</kwd><kwd>критическая зона</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Московский центр инновационных технологий в здравоохранении</institution></institution-wrap><institution-wrap><institution xml:lang="en">Moscow Center for Innovative Technologies in Healthcare</institution></institution-wrap></funding-source></award-group><funding-statement xml:lang="ru">Работа выполнена в рамках научно-исследовательского проекта московского центра инновационных технологий в здравоохранении</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Huynh MN, Ghumman A, Agarwal A, Malic C.
