Biomechanics of «Femur-Bliskunov’s distractor» system in various osteotomies

Abstract

Bimechanical models of force interaction in femurBliskunovs distractor system, biomechanical basis of various osteotomies (transverse, oblique, oblique transverse, Z-shape, Z-shape oblique) quantitative evaluation of osteotomy firmness parameters are done. The majority of osteotomies was performed with special device on the side of bone canal. Thirteen years experience of lengthening of 213 femurs (187 patients) confirms the calculated parameters. The authors prefer the Z-shape oblique osteotomy.
