Abstract
The invention relates to a method for stimulating bone growth in a mammal. The method comprises the step of exposing a bone zone where bone growth is to occur to cavitation for bringing forth haemorrhage and/or microfissures and/or to at least partially loosened bone chips at said bone zone.
Claims8
A method for stimulating bone growth in a mammal comprising the step of applying acoustic rarefaction pulses to a bone zone where bone growth is to occur, said step of applying generating at said bone zone and producing at least one symptom of the group consisting of haemorrhage, microfissures and at least partially loosened bone chips at the bone zone.
A method for stimulating bone growth in a mammal comprising the step of applying a series of positive acoustic pressure pulses each followed by a decrease of pressure to a bone zone where bone growth is to occur, said step of applying generating at said bone zone and producing at least one symptom group consisting of haemorrhage, microfissures and at least partially loosened bone chips, said series of positive acoustic pressure pulses having a repetition frequency for superimposing cavitational effects at said bone zone due to the decrease of pressure of a plurality of successive ones of said pressure pulses.
A method for stimulating bone growth in a mammal comprising the step of applying ultrasound waves having both positive and negative half cycles to a bone zone where bone growth is to occur, said step of applying generating cavitation at said bone zone and producing at least one symptom of the group consisting of haemorrhage, microfissures and at least partially loosened bone chips.
