Original Research: Basic Science in Medicine
We have already shown that low intensity pulsed ultrasonic treatment increases
rabbit radial fracture healing. The present experiment was undertaken to
find out the best duration for treatment. A complete transverse fracture was made
in the right radial bones of21 adult male rabbits by a Stanley knife. The animals
were divided into 4 groups: group 1, control groups 2, 3, and 4, experimental
groups, which received ultrasound (0.5 W /cm2, 1MHz, 2 msec on-8 msec off) for
durations of 5,10, and 15 min/day, respectively, from the day after surgery until
complete fusion was observed. Radiological studies indicated that mean duration
of healing was longer and rate of healing was lower in the control compared with
those of the experimental groups (p<0.05). However, group 3 showed the least
mean healing duration and group 2 and 3 showed the highest healing rate. Our
results revealed no deleterious effects of ultrasound on treated and untreated ipsilateral
and contralateral bones during the experiment or one month after complete
fusion of the bones, at which time ultrasound treatment was terminated.
