[Description of rearrangement of distraction reclaim in the extension of the lower extremities and elimination of their deformity in patients with various etiology of shortening].
The data of X-ray and computed tomographic studies of a long tube distraction reclaim were analyzed in 80 patients who had limb shortening and deformity of varying etiology. The analysis has shown that during distraction there is a positive correlation between the increase in the connective-tissue interlayer area of a distraction reclaim and the overall increase in the area of the distraction reclaim (their ratio is not greater than 30% under the optimal elongation conditions). During fixation there is a decrease in the ratio of the area of a growth zone to the total area of a reclaim and in its total density with a parallel increase in the density of cortical laminae of a newly formed bone. Complete organotypic rearrangement comes to the end in the range of 1-3 years depending on the magnitude of pathomorphological and biomechanical changes and limb function.
