The patients were divided into two groups: group 1 — those with degree I-II contracture (n = 31), group 2 — those with degree III-IV (n = 69). Histomorphometry of 122 Vater-Pacinian corpuscles, in which the cut plane passed through the central nucleus, was performed in paraffin and semi-thin sections of the patients’ surgical material.</p> <p><bold><italic>Results. </italic></bold>At the time of the disease onset, the difference in age medians in the groups was not statistically significant. The age median at the time of surgery (group 1 — 56.0 years; group 2 — 61.0 years, p = 0.001) and the median of the disease duration (group 1 — 5.0 years; group 2 — 9.0 years, р = 0.006) were higher in group 2, the variability in the disease duration was comparable. As it has been established, Vater-Pacinian corpuscles undergo successive reactive-destructive changes in the form of death of the central axon, stratification of the capsule, inflammation, fibrosis, deformation and destruction. The number of corpuscles is greater (р = 0.040) in group 1 — 1 (0; 3) than in group 2 — 0 (0; 6). In group 2, the corpuscles have larger diameters (group 1 — 0.85 mm; group 2 — 0.96 mm, p = 0.072), more layers of the outer capsule (group 1 –17; group 2 — 20, p = 0.032).</p> <p><bold><italic>Conclusions. </italic></bold>In patients with Dupuytren’s contracture, along with compensatory and adaptive changes in Vater-Pacinian corpuscles (hyperplasia and hypertrophy), their irreversible destructive changes develop, which, when the disease progresses to grade 3-4, lead to a loss in the number of bodies.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Введение. </italic></bold>Данные мировой литературы свидетельствуют о вовлечении телец Фатер-Пачини в патогенез ладонного фасциального фиброматоза, но сведения об их патоморфологических изменениях и гистоморфометрических характеристиках противоречивы.</p> <p><bold><italic>Цель</italic></bold> <bold><italic>исследования</italic></bold> — сравнительный анализ качественных и количественных изменений телец Фатер-Пачини у пациентов с контрактурой Дюпюитрена разной степени.</p> <p><bold><italic>Материал и методы.</italic></bold> Проведен анализ историй болезни и резецированного во время операций материала от 100 пациентов с контрактурой Дюпюитрена, распределенных на две группы: группа 1 — с контрактурой I–II ст. (<italic>n </italic>= 31), группа 2 — III–IV ст. (<italic>n </italic>= 69). В парафиновых и полутонких срезах операционного материала пациентов проведена гистоморфометрия 122 телец Фатер-Пачини, в которых плоскость среза прошла через центральное ядро.</p> <p><bold><italic>Результаты.</italic></bold> На момент начала заболевания различие медиан возраста в группах статистически незначимо. Медиана возраста на момент операции (группа 1 — 56,0 лет; группа 2 — 61,0 год; <italic>р </italic>= 0,001) и медиана давности заболевания (группа 1 — 5,0 лет; группа 2 — 9,0 лет;<italic> р</italic> = 0,006) больше в группе 2, вариативность давности заболевания сопоставима. Установлено, что тельца Фатер-Пачини претерпевают последовательные реактивно-деструктивные изменения в виде гибели центрального аксона, расслоения капсулы, воспаления, фиброза, деформации и деструкции. Количество телец больше (<italic>р</italic> = 0,040) в группе 1 — 1 (0; 3), чем в группе 2 — 0 (0; 6). В группе 2 тельца имеют большие диаметры (группа 1 — 0,85 мм; группа 2 — 0,96 мм; <italic>р</italic> = 0,072) и большее количество слоев наружной капсулы (группа 1 — 17; группа 2 — 20; <italic>р</italic> = 0,032).</p> <p><bold><italic>Заключение. </italic></bold>У пациентов с контрактурой Дюпюитрена наряду с компенсаторно-приспособительными изменениями телец (гиперплазия и гипертрофия) развиваются их необратимые деструктивные изменения, которые при прогрессировании заболевания до III–IV ст. приводят к потере численности телец.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>Dupuytren’s contracture</kwd><kwd>Vater-Pacinian corpuscles</kwd><kwd>morphology</kwd><kwd>morphometry</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>контрактура Дюпюитрена</kwd><kwd>тельца Фатер-Пачини</kwd><kwd>морфология</kwd><kwd>морфометрия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kelenjian S., Mattjie R.A., Franz R., Biedermann T., Brockow K.
