Upon admission, all patients had elbow X-rays in two projections and a CT scan. The patients were divided into 3 groups based on the type of surgical treatment: osteosynthesis with cannulated screws; osteosynthesis with a plate and cannulated screws; and resection. We evaluated radiological treatment outcomes, data from the Mayo Elbow Performance Score (MEPS), elbow range of motion, and medical history data, including the presence and timing of postoperative complications and any re-interventions performed due to these complications.</p> <p><bold>Results. </bold>Clinical results were observed in 99 (90%) patients: 44 (44%) men and 55 (56%) women. The results of surgical treatment in patients with Mason II radial head fractures were significantly better than in those with Mason III fractures, as evidenced by average MEPS scores (93.0±11.3 and 82.7±16.5, respectively), complication rates (4% vs 17%) and re-operation rates (4% vs 12%). Comparative assessment of the surgical treatment methods according to the MEPS showed significantly better results for osteosynthesis with cannulated screws compared to the use of a mini-plate (93.9±8.8 and 81.9±18.8, respectively, p = 0.005), as well as to radial head resection (93.9±8.8 and 86.4±13.1, respectively, p = 0.036). Fourteen complications were identified in 11 (11%) patients. Fracture nonunion after osteosynthesis was observed in 4 cases, secondary displacement of fragments — in 3 cases. Deep infection was diagnosed in 2 patients after 1 and 4 months after osteosynthesis. Heterotopic ossification of the elbow developed in 2 cases.</p> <p><bold>Conclusion. </bold>The findings of the study showed significantly better clinical outcomes and a lower complication rate in the medium term when radial head fractures were treated with osteosynthesis using compression screws compared to the use of a plate or resection.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность. </bold>В международном сообществе до сих пор не пришли к консенсусу, какой метод хирургического лечения предпочтителен при переломах головки лучевой кости II–III типов по классификации Mason: остеосинтез, резекция или эндопротезирование, поскольку каждый из этих методов ассоциирован с довольно высокой частотой осложнений, повторных операций и неудовлетворительных функциональных результатов.</p> <p><bold>Цель исследования </bold>— оценить среднесрочные результаты хирургического лечения переломов головки лучевой кости II и III типов по классификации Mason в зависимости от способа хирургического лечения.</p> <p><bold>Материал и методы. </bold>В исследование было включено 110 пациентов, прооперированных с 2008 по 2023 г. по поводу перелома головки лучевой кости со смещением. Всем пациентам при поступлении выполнены рентгенограммы локтевого сустава в двух проекциях и компьютерная томография. Пациенты были разделены на 3 группы по типу хирургического лечения: металлоостеосинтез канюлированными винтами; металлоостеосинтез пластиной и канюлированными винтами; резекция. Оценивали рентгенологические результаты лечения, данные опросника Mayo Elbow Performance Score (MEPS), амплитуду движений в локтевом суставе, анамнестические данные, включая наличие и сроки послеоперационных осложнений и повторных вмешательств, выполненных по поводу данных осложнений.</p> <p><bold>Результаты. </bold>Клинические результаты удалось отследить у 99 (90%) пациентов: 44 (44%) мужчин, 55 (56%) женщин. Результаты хирургического лечения у пациентов с переломами головки лучевой кости (ГЛК) типа Mason II оказались значительно выше в сравнении с переломами типа Mason III, о чем свидетельствовали средние показатели опросника MEPS (93,0±11,3 и 82,7±16,5 соответственно), частота осложнений (4% против 17%) и повторных операций (4% против 12%). Сравнительная оценка способов хирургического лечения по шкале MEPS показала значительно более высокие результаты при остеосинтезе канюлированными винтами в сравнении с использованием мини-пластины (93,9±8,8 и 81,9±18,8 соответственно, p = 0,005), а также с выполнением резекции головки лучевой кости (93,9±8,8 и 86,4±13,1 соответственно, p = 0,036). У 11 (11%) пациентов было выявлено 14 осложнений. Несращение перелома после остеосинтеза наблюдалось в 4 случаях, вторичное смещение отломков — в 3 случаях. У 2 пациентов диагностирована периимплантная инфекция по прошествии 1 и 4 месяцев после остеосинтеза. В 2 случаях развилась гетеротопическая оссификация локтевого сустава.</p> <p><bold>Заключение. </bold>Результаты исследования показали значительно лучшие клинические результаты и меньшую частоту осложнений в среднесрочном периоде при остеосинтезе переломов головки лучевой кости компрессионными винтами в сравнении с использованием пластины и резекцией.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>radial head fractures</kwd><kwd>plate fixation</kwd><kwd>radial head</kwd><kwd>resection of the radial head</kwd><kwd>cannulated screws</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>переломы головки лучевой кости</kwd><kwd>металлоостеосинтез головки лучевой кости</kwd><kwd>резекция головки лучевой кости</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Burkhart K.J., Wegmann K., Müller L.P., Gohlke F.E.
