[Comparative electronmicroscopic research on normal palmar aponeurosis and adulterated palmar aponeurosis in Dupuytren disease].

This article represents a comparative research between the normal palmar aponeurosis seen with the electron microscope and adulterated palmar aponeurosis in Dupuytren disease. For that reason, we harvested normal palmar aponeurosis from 5 patients hospitalised in emergency in our department with different posttraumatic hand lesions, and adulterated palmar aponeurosis from 15 patients with Dupuytren disease. The samples were prepared to obtain sections visualised with the electron microscope. Comparative research of these sections lead to the conclusion that in the normal palmar aponeurosis the fibroblast is visualised in its resting functional form (fibrocytes), and in the adulterated palmar aponeurosis in Dupuytren disease the fibroblast is visualised in its active, secretory, form. In Dupuytren disease we found an increased, anarchic, collagen production, clinically demonstrated by nodules and fibrous strips. This paper is just a preliminary stage of a research looking for alternative, noninvasive, therapeutical methods in Dupuytren disease (ex. : effects of electromagnetic field made by millimeter waves on the adulterated palmar aponeurosis cell structure).
