Summary: | In the experiment on 5 dogs weighing from 6 to 10 kg the results of applying ultrasonic technology of polymer removal and treatment of bone mantle in revision total hip and knee arthroplasty were examined. As a source of high-amplitude low-frequency ultrasound an ultrasonic surgical apparatus «Tier», operating at 42 kHz, and provides the intensity of exposure at the end of the waveguide to 1200 W / cm2 was applied. The physical parameters of the influence of ultrasound on the bone were studied. The analysis of the rate of removal of the old plastic mantle was performed. The results of experimental and clinical studies proved that the use of ultrasound frequency of 42.5 kHz facilitates the removal of old bone cement in revision arthroplasty of large joints, reduces the duration and severity of the operation. |
