    <p>ВВЕДЕНИЕ. Биомеханические изменения, вызванные разновеликостью нижних конечностей, являются предметом изучения, и этот вопрос вызывает разногласия среди специалистов.&#13;
ЦЕЛЬ. Оценка влияния разновеликости нижних конечностей и ее компенсации у детей на амплитуду движения таза во  фронтальной плоскости при ходьбе.&#13;
МАТЕРИАЛ И МЕТОДЫ. Обследован 21 пациент с разновеликостью нижних конечностей. Средняя величина разновеликости составила 2,86% (от 0,23% до 6,12%). Биомеханическое обследование состояло в проведении динамической оптической  компьютерной топографии. Исследование проводилось в стандартной обуви без компенсации и в компенсирующей  разновеликость обуви. Средняя величина компенсации составила 14 мм (от 5 до 45 мм). Группу сравнения составили 19 здоровых детей без разновеликости нижних конечностей. В ходе обследования определялся угол асимметрии фронтальных колебаний таза, который рассчитывался как абсолютное значение разницы наклона вправо и влево.&#13;
РЕЗУЛЬТАТЫ И ОБСУЖДЕНИЕ. При использовании компенсации у детей с разновеликостью нижних конечностей амплитуда движений таза менялась незначительно – в среднем на 1,84°. В группе сравнения (здоровые дети) при имитации  разновеликости авторы также не наблюдали изменения фронтального колебания таза в сравнении с пробами без компенсации. Наиболее очевидным объяснением этого феномена является формирование дополнительных механизмов компенсации разной длины нижних конечностей.&#13;
ЗАКЛЮЧЕНИЕ. Компенсация разной длины нижних конечностей требует индивидуального подхода и проведения  дополнительных обследований пациента при ходьбе. Дальнейшие исследования позволят расширить наши представления о  целесообразности и тактике компенсации разновеликости нижних конечностей, как при консервативном лечении, так и при планировании оперативных вмешательств.</p>

    <p>INTRODUCTION. Biomechanical abnormalities caused by limb length discrepancy are controversial problems of pediatric orthopedics.&#13;
AIM. To assess the influence of limb length discrepancy and its compensation in children on the amplitude of pelvic motion in the frontal plane during walking.&#13;
MATERIAL AND METHODS. We examined the study group of 21 patients with (the average discrepancy was 2,86% (from 0,23% to 6,12%). Biomechanical examination consisted of dynamic optical computed topography. The study was carried out in standard shoes and in shoes with compensation. The average compensation was 14 mm (from 5 to 45 mm). The comparison group consisted of 19 healthy children without limb length discrepancy. The angle of frontal asymmetry of the pelvis was calculated as the absolute difference in inclination.&#13;
RESULTS AND DISCUSSION. When compensation was used, the amplitude of pelvic movements changed insignificantly, by an average of 1.84°, in children with discrepancy of the lower limbs. In the comparison group (healthy children), we also did not observe any changes in frontal pelvic oscillation when imitating variability compared to tests without compensation. The most obvious explanation for this phenomenon is the formation of additional compensation mechanisms for different lengths of the lower limbs.&#13;
CONCLUSION. Compensation of limb length discrepancy requires an individualized approach and additional walking examinations of the patient. Further research will expand our understanding of the role of compensation for limb length discrepancy both in conservative treatment and in planning for surgical interventions.</p>
