Patients were divided into two groups: the osteosynthesis group (O, n = 23) and the arthroplasty group (A, n = 25). In both groups, 12 months after the surgery, we conducted a survey using a specially developed subjective assessment system.</p> <p><bold>Results.</bold> No significant difference was found between the groups in the subjective assessment of treatment outcomes one year after osteosynthesis of PHF and reverse shoulder arthroplasty. However, in patients from both groups, different criteria were identified as more significant in subjective assessment of the fracture treatment outcome. In A group, following criteria were significant: restricted range of motion in the upper limb and the percentage of functional recovery of the upper limb. In O group, the most prognostically important criteria for treatment assessment were the VAS point and the patients’ self-assessment of their contribution to the rehabilitation of the operated arm after surgery.</p> <p><bold>Conclusion.</bold> In four-part fractures of the proximal humerus, plate osteosynthesis can be expected to yield treatment outcomes comparable to those of reverse shoulder arthroplasty. Our study highlights the importance of subjective assessment of quality of life and patient satisfaction, which have become key components in clinical decision-making in the treatment of four-part fractures of the proximal humerus.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность. </bold>Четырехфрагментарные переломы проксимального отдела плечевой кости (ПОПК) представляют наибольшие трудности при выборе метода лечения.</p> <p><bold>Цель исследования </bold>— сравнить среднесрочные клинические исходы хирургического лечения пациентов с четырехфрагментарными переломами хирургической шейки плечевой кости после неосложненного остеосинтеза и неосложненного эндопротезирования с использованием разработанной системы субъективной оценки результатов лечения.</p> <p><bold>Материал и методы. </bold>В ретроспективное исследование были включены пациенты в возрасте 18–90 лет с четырехфрагментарными переломами и переломовывихами ПОПК давностью до 14 сут. Пациенты были разделены на две группы: группа остеосинтеза (О, n = 23) и группа эндопротезирования (Э, n = 25). В обеих группах через 12 мес. с момента выполнения операции был проведен опрос с использованием специально разработанной системы субъективной оценки результатов лечения.</p> <p><bold>Результаты. </bold>Значимой разницы между группами в субъективной оценке результатов лечения через год после остеосинтеза ПОПК и эндопротезирования плечевого сустава выявлено не было. Однако у пациентов в группах были выделены разные критерии в качестве более значимых, которые влияли на субъективную оценку результата лечения перелома. В группе эндопротезирования ими стали ограничение движений в верхней конечности и процент восстановления функции верхней конечности. В группе остеосинтеза прогностически важными в оценке лечения стали уровень боли по 10-балльной ВАШ и личный вклад в реабилитацию оперированной руки после операции.</p> <p><bold>Заключение. </bold>При выполнении накостного остеосинтеза у пациентов с четырехфрагментарным переломом проксимального отдела плечевой кости можно ожидать сопоставимых с реверсивным эндопротезированием плечевого сустава результатов лечения. Исследование показывает важность субъективной оценки качества жизни и удовлетворенности пациентов, которые становятся важными компонентами принятия клинических решений при лечении четырехфрагментарных переломов проксимального отдела плечевой кости.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>proximal humerus fracture</kwd><kwd>reverse shoulder arthroplasty</kwd><kwd>plate osteosynthesis</kwd><kwd>ORIF</kwd><kwd>quality of life</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>перелом проксимального отдела плечевой кости</kwd><kwd>реверсивное эндопротезирование плечевого сустава</kwd><kwd>накостный остеосинтез</kwd><kwd>ORIF</kwd><kwd>качество жизни</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Roux A., Decroocq L., El Batti S., Bonnevialle N., Moineau G., Trojani C. et al.
