Subtalar arthrodesis is indicated after calcaneal fractures with progressive osteoarthritis. Distraction subtalar arthrodesis is recommended in cases of severe depression of the posterior articular facet to restore hindfoot alignment.</p> <p><bold>AIM:</bold><italic> </italic>The work aimed to improve the surgical management strategy for post-traumatic calcaneal deformities.</p> <p><bold>METHODS:</bold> Between 2021 and 2024, 27 patients with severe post-traumatic calcaneal deformities underwent surgery at the Department of Traumatology and Orthopedics No. 4, N.N. Priorov National Medical Research Center of Traumatology and Orthopedics, Moscow, Russia. The cohort included 7 women and 20 men, with a mean age of 35 years (22–56 years). All procedures were performed by the same surgeon. The mean time from injury to surgery was 24.8 months (9–72 months).</p> <p><bold>RESULTS:</bold><bold> </bold>Treatment outcomes in patients included in the study were assessed 12 and 24 months after surgery. The mean follow-up period was 26.2 months (12–56 months). The mean preoperative visual analog scale (VAS) score was 5.1 (2–9), which decreased to 0.8 (0–3) postoperatively, indicating a significant reduction in pain (<italic>p</italic> &gt; 0.001). The mean AOFAS hindfoot score was 42 preoperatively (39–72) and 85 postoperatively (60–92), with an improvement in questionnaire scores (<italic>p</italic> &gt; 0.001). Complications were reported in 13 patients; two patients required revision surgery. Dynamic pedobarography showed an increase in peak and mean pressure integrals across the foot. The mean heel contact time decreased significantly from 640 ± 166 ms preoperatively to 515 ± 141 ms postoperatively (<italic>p</italic> &lt; 0.003). These values were comparable to those of the contralateral healthy foot: 530 ± 177 ms, respectively.</p> <p><bold>CONCLUSION:</bold> Distraction subtalar arthrodesis was performed in patients with severe post-traumatic calcaneal deformity (talus inclination angle &lt;8°). Distraction was essential to restore the height of the calcaneus and normal anatomical relationships of the hindfoot as a whole. Patients were satisfied with the outcomes, which were confirmed not only clinically and radiographically, but also biomechanically via dynamic pedobarographic assessment.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold><bold> </bold>Переломы пяточной кости, внутрисуставные, импрессионные со смещением отломков после консервативного или неадекватного хирургического лечения, могут привести к серьёзной ортопедической проблеме. Артродез подтаранного сустава выполняется после переломов пяточной кости с развитием прогрессирующего остеоартроза. Дистракционный артродез подтаранного сустава показан при выраженной депрессии задней суставной фасетки для восстановления нормальных взаимоотношений заднего отдела стопы.</p> <p><bold>Цель.</bold> Оценить эффективность и безопасность новой тактики хирургического лечения посттравматической деформации пяточной кости.</p> <p><bold>Материалы</bold><bold> </bold><bold>и</bold><bold> </bold><bold>методы.</bold> В отделении травматологии и ортопедии № 4 ФГБУ «НМИЦ ТО им. Н.Н. Приорова», г. Москва, в период 2021–2024 гг. было проведено оперативное лечение 27 пациентам с тяжёлой посттравматической деформацией пяточной кости, из них 7 женщин и 20 мужчин, средний возраст которых составил 35 лет (от 22 до 56 лет). Все пациенты оперированы одним хирургом. Среднее время от момента травмы до оперативного лечения — 24,8 мес. (от 9 до 72 мес.).</p> <p><bold>Результаты.</bold><bold> </bold>Оценка результатов лечения пациентов, принявших участие в исследовании, проводилась в интервале 12 и 24 мес. после операции. Средний период наблюдения составил 26,2 мес. (от 12 до 56 мес.). Средний показатель визуальной аналоговой шкалы до операции составил 5,1 (от 9 до 2), после операции — 0,8 (от 3 до 0), отмечено значительное снижение болевого синдрома (<italic>р</italic> &gt;0,001). Средний показатель AOFAS заднего отдела стопы до операции составил 42 (от 39 до 72), после операции — 85 (от 60 до 92), также отмечено улучшение показателей опросника (<italic>р</italic> &gt;0,001). Осложнения наблюдались у 13 пациентов, 2 пациентам потребовалось повторное хирургическое вмешательство. По результатам динамической педобарографии отмечено увеличение показателей пикового и среднего интеграла давления для всей стопы, среднее время контакта пятки значительно уменьшилось — с 640±166 мс до операции до 515±141 мс после операции (<italic>р</italic> &lt;0,003). Эти показатели были схожи с показателями здоровой стопы — 530±177 мс соответственно.</p> <p><bold>Заключение.</bold> Дистракционный артродез выполнялся пациентам при тяжёлой посттравматической деформации пяточной кости (угол инклинации таранной кости менее 8 градусов). Дистракция необходима для восстановления высоты пяточной кости и нормальных взаимоотношений заднего отдела стопы в целом. Пациенты были удовлетворены результатом лечения, который был подтверждён не только клинически, рентгенологически, но и путём биомеханического исследования, при помощи динамической педобарографии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>calcaneal fracture</kwd><kwd>post-traumatic deformity</kwd><kwd>reconstruction</kwd><kwd>subtalar arthrodesis</kwd><kwd>distraction</kwd><kwd>calcaneal osteotomy</kwd><kwd>bone grafting</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>перелом пяточной кости</kwd><kwd>посттравматическая деформация</kwd><kwd>реконструкция</kwd><kwd>подтаранный артродез</kwd><kwd>дистракция</kwd><kwd>остеотомия пяточной кости</kwd><kwd>костная пластика</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Shkuro KV, Zeinalov VT, Arapova IA, Levin AN, Vasiliev DO.
