ABSTRACT

Pathophysiology A number of different theories exist addressing the pathophysiology of Dupuytrens

disease: 1. Murrell’s theory is that Dupuytren s contracture is initiated by multifactorial

vascular compromise of the palmar vessels. The ischemia causes liberation of endothelial xanthine oxidase-derived free radicals. The ensuing cycle of cell dam­ age, fibroblast proliferation and collagen deposition ultimately leads to a further narrowing o f the vessels with more ischemia (and therefore explains the chronic and progressive nature of the disease).
