[Roentgeno-densito-planimetric evaluation of the bones after correction of the defect].

In an experiment with 52 dogs (2 experimental series) there were studied, by means of a roentgeno-densito-planimetric method, changes of bone substance in the process of the upper half of tibia defect compensation with the aid of transplant, displaced within the defect, and distraction regenerate, formed therewith. The data obtained indicated that formation and mineralization of new bone substance have been accompanied by intensification of the transplanted bone osteoporosis. Osteoporosis manifestation has been determined by an amount of newly formed bone substance and increased with the increase of the distraction regenerate size. Osteoporosis manifestation decreased with application of large bone transplant that allows to preserve in greater degree the transplanted bone strength in the process of restructuring.
