WebIn experiments to be funded separately and conducted at the Laboratory for Experimental Surgery in Davos, Switzerland, Perren and co-workers will provide an in vivo model for the investigation of this hypothesis. The mid-diaphysis of sheep tibiae will be osteotomized and fixed with a modified internal fixation plate to produce a uniform 2 mm gap. WebBy providing a modern perspective on Stephan Perren’s strain theory, reverse dynamisation perhaps holds the key to tipping the balance in favour of a more rapid and reliable union when treating acute fractures, osteotomies, non-unions and other circumstances where it is necessary to regenerate bone.

Webformula (PERREN, 1979; PERREN, 2002): This theory suggests that the strain which causes healthy bone tissue to fail is the upper limit of tolerable deformation for this tissue’s regeneration (JAGODZINSKI; KRETTEK, 2007). The amount of deformation that animal tissues can withstand while ε = ΔL x 100 L maintaining its function varies widely.
