title: [Biochemical and anatomic changes in the muscles after leg bone lengthening by the Ilizarov method].
abstract: In process of crus lengthening, following the method, given by Ilizarov G. A., with 22 adult patients have been studied the peculiarities of metabolic processes of muscle tissue of the lengthened segment as well as the muscle tissue structural changes. As the tests were used; determination of lactate dehydrogenase content and its isoenzymatic spectrum in the blood serum, the residual products of lactic and pyruvic acids glycolysis, relating to the higher indications of the internal medium of an organism; carboxylase activity detection. Energy provision of an organism was estimated according to the ATP content; anatomical state of muscles of the lengthened extremity segment and muscle tissue structure were estimated by means of contrast myography. Dynamics of biochemical indexes suggests that the sparing character of an operation, patient mobility from the first days, preservation of locomotive and supporting function contribute to prevention of metabolic disease and ensure earlier transformation of catabolic reaction to anabolic one. Carboxylase and lactate-dehydrogenase activity increase indicates the biochemical adaptation of an organism. Metabolic changes well correlate with the detected structural changes in the lengthened crus muscles.
