has been reported as the most common type of extremity fractures in adults. No treatment method has been introduced definitely for this type of fracture, especially for maintaining hand function in the best state.</p> <p><bold>The aim of this study</bold> — to assess the functional and radiological outcomes following three surgical methods, including external fixation, K-wire and external fixation with pinning.</p> <p><bold>Methods.<italic> </italic></bold>This parallel-designed randomized controlled trial was conducted on adult patients with intra-articular fracture of distal radius. The participants were allocated in three research groups with block random sampling, and were matched for their age and gender. Primary outcome was radiographic parameters, including radial inclination, radial height, ulnar variance and dorsal/palmar tilt. Secondary outcome was the patient’s performance examined with DASH and PRWE questionnaires. All participants were followed 6, 12 and 24 weeks after the surgery for evaluation of these outcomes.</p> <p><bold>Results.<italic> </italic></bold>Totally, 78 patients, including 42 male and 36 female with mean age of 46.94±11.05 years completed the research protocol. Although the four radiologic primary endpoints were in the normal clinical range after the intervention, a significant statistical difference was observed between the three groups (р&lt;0.001). Also, both DASH and PRWE score showed a significant decrease after the therapeutic interventions (р&lt;0.001).</p> <p><bold>Conclusion.<italic> </italic></bold>The statistically significant difference in the research outcomes of the external fixation with pinning can show that this treatment method theoretically preserves the anatomical condition better than the other two methods, and probably has better functional effects on short-term and intermediate-term results following the surgery.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность.<italic> </italic></bold>Переломы дистального отдела лучевой кости являются самым распространенными среди всех переломов конечностей у взрослых. Однако до сих пор не предложено единой методики лечения данных переломов, которая обеспечивала бы наилучшую сохранность функции кисти.</p> <p><bold>Цель исследования<italic> </italic></bold>— оценить функциональные и рентгенологические результаты после трех вариантов хирургического лечения: внешней фиксации, фиксации спицами и внешней фиксации в сочетании со спицами.</p> <p><bold>Материал и методы.<italic> </italic></bold>В параллельное рандомизированное контролируемое исследование было включены взрослые пациенты с внутрисуставными переломами дистального отдела лучевой кости. Методом блочной рандомизации они были разделены на три группы, сопоставимые по полу и возрасту. В качестве первого критерия оценки использовались рентгенометрические параметры: лучелоктевой угол, высота шиловидного отростка лучевой кости, локтелучевой индекс и тыльный/ладонный наклон. Вторым критерием была оценка функциональных результатов по шкалам DASH и PRWE. Контрольные осмотры пациентов проводились на сроках 6, 12 и 24 нед. после операции.</p> <p><bold>Результаты.<italic> </italic></bold>На всех этапах исследования была проведена оценка функциональных результаты 78 пациентов (42 мужчины и 36 женщин), средний возраст которых составил 46,94±11,05 лет. Несмотря на то, что после хирургического вмешательства все четыре первичных рентгенометрических показателя были в пределах нормы, между тремя исследуемыми группами наблюдалась статистическая значимая разница (<italic>р</italic>&lt;0,001). Кроме того, отмечалось значительное снижение показателей по шкалам DASH и PRWE после операции (<italic>р</italic>&lt;0,001).</p> <p><bold>Заключение.<italic> </italic></bold>Статистически значимые отличия в результатах в случае выполнения внешней фиксации с использованием спиц могут свидетельствовать о том, что гипотетически данный метод лечения обеспечивает большую сохранность анатомии сустава, чем два других метода, и, вероятно, способствует получению лучших ближайших и среднесрочных функциональных результатов после операции.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>distal radius fracture</kwd><kwd>surgical procedures</kwd><kwd>pinning</kwd><kwd>external fixation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>перелом дистального отдела лучевой кости</kwd><kwd>хирургические методы лечения</kwd><kwd>фиксация спицами</kwd><kwd>внешняя фиксация</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Babol University of Medical Sciences</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ermutlu C., Mert M., Kovalak E., Kanay E., Obut A., Öztürkmen Y.
