[Correction of extensive defects of long bones by using bi- and multifocal distraction-compression osteosynthesis].

Replacement of extensive defects in long bones on the basis of one or more osteotomies is analysed. The authors substantiate the principles and the new methods of +multifocal distraction-compression osteosynthesis which allow healing of the fracture to be combined with accelerated replacement of the bone defect. The errors, complications, and the results of treatment of 104 patients are discussed to evaluate the efficacy of the applied methods and confirm the drawn conclusions. Particular attention is paid to the significance of a complex of optimal mechanical and biological factors in the formation of the regenerative tissue in accelerated replacement of the bone defects on the basis of several osteotomies. It is shown that the advantage of the new variants of the methods of replacement of long tubular bones on the basis of several osteotomies consists in combination of the healing of open fractures with accelerated restoration of the length of the extremity.
