The Mechanical Properties of the Palmar Aponeurosis and their Significance for the Pathogenesis of Dupuytrens ContractureFrom the Ludwig Boltzmann Institute for Experimental Plastic Surgery, Vienna, Austria Correspondence: o. Univ. Prof. Dr H. Millesi, Ludwig Boltzmann Institut für Experimentalle Plastische Chirurgie, A-1090 Wien, Lazarettegasse 14 (Bauteil 82), Austria. Normal tendons and palmar aponeuroses from patients with carpal tunnel syndrome and tissues of the palmar aponeuroses from patients with Dupuytrens contracture were subjected to biomechanical tests. Several parameters characterizing the viscoelastic load response of the tissues were investigated. The tissues from patients with Dupuytrens contracture were classified according to their macroscopic and histological appearance into apparently normal palmar aponeuroses, thickened fibre bundles and contracture bands. There were biomechanical differences between the normal palmar aponeuroses and the apparently normal palmar aponeuroses indicating that biomechanical changes occur before thickening of fibres or cellular proliferation can be observed. Significant biomechanical changes occurred between apparently normal palmar aponeuroses and thickened fibre bundles.
