Abstract: A method of ultrasonic bone-therapy subjects a bone to an ultrasonic excitation pulse signal of finite duration, supplied to a transducer next to the bone, and involving a sinusoidal signal in the ultrasonic region to approximately 2 MHz peculiarly modulated by a sinusoidal signal with frequency between about 0 Hz and about 25 kHz; the excitation signal is repeated in the range of 1 to 5000 Hz. The exposure time for therapy is chosen to be in the range of 5 minutes to 1 hour, for 1 to 3 times a day, for a period of days as necessary for healing or for promoting bone growth and ingrowth. An apparatus for implementing the above method for ultrasonic bone therapy is disclosed comprising a transducer having a transmitting and a receiving element, a special waveform signal generator, and a computer for performing the necessary operations defining a preferred treatment regime.
