Every bone fracture must be held rigid and, because of the long healing process, infringes on the individual's life-style. Treatment with ultrasound, however, may reduce the healing time 30-50% since the piezoelectric effect of ultrasound acts as a callus stimulator. This book documents more than twenty years of clinical experience with ultrasound treatment of fractures. The authors give statistical evidence and show numerous X-rays to document their success. They also include a summary of experimental studies. The method is described in detail so that the practicing physician can easily learn how to apply it.
