All patients underwent surgery using a minimally invasive technique. The Guiding Device Group consisted of 21 patients who underwent osteotomy with the use of the original guide. The Freehand Group included 21 patients who underwent osteotomy without the guide. At the end of the procedure, the duration of the surgery and the radiation dose – measured using the image intensifier sensors – were recorded.</p> <p><bold>Results</bold><bold>.</bold> The median duration of surgery in the Guiding Device Group was 25.00 minutes [25.00; 30.00], while in the Freehand Group it was 45.00 minutes [40.00; 57.50]. The observed differences were statistically significant (p &lt; 0.001). The mean radiation dose was 0.30±0.06mGy in the group where the guide was used, and 0.79±0.20mGy in the group where guidewires for screws were inserted freehand. The mean difference between the groups for this parameter was 0.49mGy (95% CI 0.39-0.58mGy; p &lt; 0.001). Pain intensity assessed by the VAS at 2, 4, and 8 weeks, and at 6 months postoperatively, was lower in patients who underwent surgery with the guide (p &lt; 0.05 for all time points).</p> <p><bold>Conclusion</bold><bold>. </bold>The use of the original guiding device in minimally invasive corrective osteotomies for hallux valgus deformity significantly reduced operative time and radiation exposure for both the patient and the surgeon.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность. </bold>Малоинвазивная корригирующая остеотомия при вальгусной деформации первого пальца стопы является высокотехнологичным вмешательством, отдельные этапы которого могут быть длительными и требуют интраоперационного флюороскопического контроля.</p> <p><bold>Цель исследования </bold>— оценить влияние применения оригинального направителя при выполнении малоинвазивной корригирующей остеотомии первой плюсневой кости на продолжительность оперативного вмешательства, время работы электронно-оптического преобразователя и величину дозы рентгеновского облучения.</p> <p><bold>Материал и методы.</bold> В исследовании приняли участие 42 пациента с hallux valgus, разделенные на две группы. Все пациенты были прооперированы с использованием малоинвазивной хирургической техники. В группу «Направитель» вошел 21 пациент (21 стопа), которым была выполнена остеотомия с применением оригинального направителя. Пациентам группы «Свободная рука» (21 пациент, 21 стопа) остеотомия выполнялась без использования направителя. После завершения операции регистрировали ее длительность, а также дозу рентгеновского излучения, измеренную с помощью датчиков электронно-оптического преобразователя.</p> <p><bold>Результаты. </bold>Медиана длительности операции у пациентов группы «Направитель» составила 25,00 мин. [25,00; 30,00], а в группе «Свободная рука» — 45,00 мин. [40,00; 57,50]. Выявленные различия были статистически значимыми (p&lt;0,001). Средняя величина дозы облучения была равна 0,30±0,06 мГр в группе, где использовался направитель, и 0,79±0,20 мГр— в группе, где направляющие спицы для винтов проводились методом «свободной руки». Средняя разность между группами исследования по этому показателю составила 0,49 мГр (95% ДИ 0,39–0,58 мГр; p&lt;0,001). Интенсивность болевого синдрома по ВАШ на сроках 2, 4, 8 нед., 6 мес. после операции была ниже у пациентов при использовании направителя (для всех сроков p&lt;0,05).</p> <p><bold>Заключение.</bold> Применение оригинального направителя при выполнении малоинвазивных корригирующих операций у пациентов с вальгусной деформацией первого пальца стопы позволило сократить длительность оперативного вмешательства и лучевую нагрузку на пациента и хирурга.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>hallux valgus, bunion</kwd><kwd>valgus deformity of the first toe</kwd><kwd>osteotomy guide</kwd><kwd>minimally invasive corrective osteotomy</kwd><kwd>chevron osteotomy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>hallux valgus</kwd><kwd>вальгусная деформация первого пальца</kwd><kwd>направитель для корригирующей остеотомии</kwd><kwd>малоинвазивная корригирующая остеотомия</kwd><kwd>шевронная остеотомия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Bia A., Guerra-Pinto F., Pereira B.S., Corte-Real N., Oliva X.M.
