Abstract


Purpose. To study the possibility of using gamma-scintigraphy for evaluation of bone tissue vascularization and formation in the zone of regenerated bone in order to determine the proper rate of distraction, the periods of bone fragment fixation, and to analyze the efficiency of acupuncture point (APP) stimulation effect on the process of regeneration.
Materials and Methods. The features of vascularization, formation and remodeling the distraction regenerated bone substance of forearm bones in the rabbits when inserting transosseous elements through APP studied experimentally using gamma-scintigraphy. One of the forearms underwent 1-mm lengthening by the Ilizarov method.
Results. The prolonged APP irritation with the inserted transosseous elements has been demonstrated to result in acceleration of vascularization of the regenerated bone, as well as in intensification of formation of the bone substance, both of which by their characteristics are most similar to the parameters of intact animals’ structures.
Conclusion. The results of the study using gamma-scintigraphy of distraction regenerated bone of forearm bones are an objective measure of its vascularization evaluation with the help of which combined with the known techniques (radiography and multispiral computed tomography /MSCT/) the degree of regenerated bone maturity and the process of osteogenesis can be evaluated.
