RESUMO
For the purpose of comparative analysis of the clinical course of fascial fibromatosis and tissue composition of the palmar aponeurosis in patients of different age groups Ñase reports and histological surgical material from 179 Dupuytren's contracture patients treated in 2014-2018 were analyzed. Patients were distributed in age groups: the 1st - younger than 50 years, the 2nd - 50-65 years, the 3rd - over 65 years old. In all groups four variants of Dupuytren's contracture clinical course were noted: swift, fast, benign and deffered. The rates of third-fourth levels of contracture in age groups were 50, 54 and 76% respectively. In groups 2 and 3 the volume per cents of hyperplastic connective tissue and adipocytes in palmar aponeurosis were decreased though body mass indexes were increased in comparison with group 1 (p<0,005). The signs of fat tissue vascularity and perivascular inflammatory infiltration were most pronounced in group 1, in group 3 per cent of vessels with adventitial fibrosis was significantly increased. The obtained data may be used for age-oriented treatment protocols and individual prognosis of fascial fibromatosis recurrence and spread.
