An apparatus and method for healing bone fractures, pseudoarthroses and the like with the use of ultrasound. An ultrasound transducer, in contact with the skin of the patient, transmits ultrasound pulses to the site of the bone defect. The nominal frequency of the ultrasound is 1.5 MHz, the width of each pulse varies between 10 and 2,000 microseconds, and the pulse repetition rate varies between 100 and 1,000 Hz. The power level of the ultrasound is maintained below 100 milliwatts per square centimeter. Treatments which last no more than about 20 minutes per day have been found to heal defects in a wide variety of cases in less than two months.
