Mean age of children at the moment of procedure was 4 years and 3 months (min — 1 year, max — 14 years).

Patients were divided into three groups depending on extirpation technique: 1)  extirpation from two approaches using a high-speed burr; 2) from a single dorsal approach using the same extirpation technique; 3) from dorsal approach using ultrasonic bone scalpel. Surgery time was 208±72 min in the first group, 187±54 min in the second group, and 170±30 min in the third group; blood loss volume was 181±39, 181±53, 132±73 ml respectively in the groups, or 11.5±4.3%, 9.4±2.8% and 9.6±5.2% of total blood volume, respectively.</p><p><italic><bold>Conclusion</bold>. </italic>Surgical approach and hemi-vertebrae extirpation technique in children have a varying impact on<italic> </italic>surgery time and intraoperative blood loss, and the least values were reported for posterior approach using ultrasonic bone scalpel.</p></abstract><trans-abstract xml:lang="ru"><p><italic><bold>Цель исследования</bold> — </italic>изучить влияние особенностей техники экстирпации полупозвонков при моносегментарной реконструкции на травматичность операции.</p><p> <italic><bold>Материал и методы</bold>. </italic>В рамках моноцентровой<italic> </italic>4-летней когорты<italic> </italic>34<italic> </italic>пациентам были выполнены<italic> </italic>36<italic> </italic>моно-сегментарных экстирпаций полупозвонков с задней инструментальной фиксацией. Средний возраст детей на момент операции составил 4 года 3 мес. (min — 1 год; max — 14 лет).

Были сформированы три группы пациентов в зависи-мости от техники экстирпации полупозвонка: 1) экстирпация из двух доступов с использованием высокоско-ростного бора; 2) из одного дорсального доступа с той же техникой экстирпации; 3) из дорсального доступа с  использованием ультразвукового костного скальпеля). Длительность операции составила в первой, вто-рой и третьей группах соответственно 208±72 мин, 187±54 мин, 170±30 мин, а объем кровопотери — 181±39, 181±53, 132±73 мл, или 11,5±4,3%, 9,4±2,8% и 9,6±5,2% от ОЦК.</p><p><bold> <italic>Выводы. </italic></bold>Оперативный доступ и техника экстирпации полупозвонков у детей в разной степени влияют<italic> </italic>на длительность операции и операционную кровопотерю, при этом наименьшие значения достигаются при операции из заднего доступа, осуществляемой с использованием ультразвукового костного скальпеля.</p></trans-abstract><kwd-group xml:lang="en"><kwd>congenital scoliosis</kwd><kwd>hemi-vertebra</kwd><kwd>extirpation of hemi-vertebra</kwd><kwd>ultrasonic bone scalpel</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>врожденный сколиоз</kwd><kwd>полупозвонок</kwd><kwd>экстирпация полупозвонка</kwd><kwd>ультразвуковой кост-ный скальпель.</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
