Clinical and experimental researches were conducted to study the possibilities for enhancing the efficiency of treatment of open composite comminuted and crushed fractures of long bones with the help of repercussive action of electrets. The results of roentgenomorphometric, clinical and biomechanical researches have shown the efficiency of electrets that could shorten the healing time of the infected wounds, stop the inflammatory reaction and promote the repairing process of bones. The application of electrets using the repercussive methods in complex treatment of complicated open fractures in cases with multiorgan and concomitant injuries creates favourable conditions for the healing process. This method is simple, atraumatic and economical.
