Biomechanical Characterization of Tissues in Dupuytren’s Disease:

摘要: The aim of this study was to characterize mechanical properties tissues Dupuytren's disease and attempt identify changes due cellular activity. Tensile tests confirmed the heterogeneity tissue with distinct stress-strain curves for three types normally present, namely, cord, transition zone nodule. tensile strength cord nearly twice that nodule tissue, but latter as stretchable cord. In contrast, had stretchability It found loading stimulated a response demonstrated by an increase in creep strain rate at 37°C compared 4°C using vitro culture test. more than seven times nominal stress 0.75 MPa.
